4/6/2009 Inactive Carassius auratus 3/26/09 Goldfish... period 3/15/09 Goldfish laying over--but not in the way I have read in the FAQs 2/10/09 Hi Crew, <Hello,> I have been searching and reading your website for several days trying to figure out what is going on...I have had no luck finding a post that is similar to what I have going on. It is a two fold problem Here are the details: We have/had three fancy goldfish--two Orandas and some sort of grey double-tailed goldfish all about 3 inches nose to tail-- in a 50 gallon tank. We have a small pond pump that is set up to filter through ammo-Carb. <Do understand that neither of these products is terribly useful here. A good biological filter is what you need. Ammonia remover (zeolite) "dies" after 2-4 weeks, tops, and needs replacing. Carbon serves little purpose at all, and to do anything useful needs to be replaced every couple of weeks. Goldfish need a decent size filter, 6x the volume of the tank in turnover per hour. So you'll need a canister filter rated at around 300 gallons per hour.> We also have large pea size gravel and large rocks on the bottom of the tank Our nitrites and ammonia have been consistently 0 ppm. <If you really are filtering through just zeolite and carbon, I'm surprised if this is the case, unless of course you are replacing the zeolite regularly or have some other type of filter installed as well.> Our nitrates have been consistently below 20 ppm and our pH is around 7--I use the color charts so I am guessing on exacts--but they are always the right color. The temperature is also consistently about 68 degrees. We feed all fresh food: peas, grapefruit, zucchini, some dried Nori, blood worms, and sometimes a bit of egg. I am also usually very good about not giving them more than they can eat in just a few minutes. <OK.> The first part of the problem is that one of the Orandas, when we first purchased him about 6 months ago presented with some sort of whitish fuzz/fungus while in isolation. We treated him with salt and Melafix (which I have heard conflicting reports about the utility of). <Neither Melafix nor salt are reliable treatments, though both do have mild anti-fungal properties.> The white fuzz went away and we introduced him into the main tank. About a week ago the fuzz reappeared and we isolated and treated him again. During this time I read lots of posts on WetWeb and searched all over but couldn't find a satisfactory treatment option besides what we did--any thoughts on that front would be appreciated (I read about various antibiotics but was hesitant to treat so aggressively when I wasn't even sure what it was. He seemed to get progressively worse and died about 7 days after first showing up with the fuzz. <Par for the course when people use Melafix, I'm afraid. It's like treating a stroke with aspirin. Whatever beneficial properties Melafix may have, the simple fact is that it is easily outgunned by any established infection. As for treating "aggressively", what would you ask your doctor to do if you had what was effectively gangrene? Use an antibiotic, or ask him to stick with soapy water? Balance risk against benefit: fungal infections can kill, and kill quickly, so while copper or organic dyes are toxic, the risk of causing death through their use is a fraction of the risk from not treating at all.> The second part of the problem is now my other Oranda is showing some very slight signs of fuzz (basically just a slight opaqueness on his pectoral fins and anal fins). For the last few months he has seemed to have some sort of narcolepsy as well. He will be swimming along and then suddenly seems to forget what he's doing and just sink down to the bottom. Not violently or crazily, just gently down to the bottom. Now though, he has begun tipping over when he does this. He will gently float down to the bottom and then gently over onto his side. After a while he will "wake up" and start swimming around again. Additionally it seems that his swimming is more hectic than it used to be--sort of dashing around. This behavior started last week. He still seems to be eating normally and interacting with his tank mate normally. This usually wouldn't worry me too much--I have noticed goldfish are kind of odd little guys--but he seems to stop breathing or breath really slowly when this happens. <May be genetic, or due to the deformed anatomy of the fancy Goldfish in question. But could equally easily be a reaction to water quality, temperature or diet. Ammonia and nitrite should be zero, but often aren't. Given your filter system as described, I'm dubious water quality is as good as you think it is, especially given one fish has already died from a fungal infection, something commonly related to water quality. The temperature is perfect for Fancy Goldfish so not worried there. Diet should be okay, though would avoid egg because it does cause constipation in some animals (not sure about fish).> So the two part problem is this: could you please recommend something that I could have done to save the first Oranda for future reference and please tell me if there is something I can do to save this second Oranda. I really like goldfish, don't mind the weekly water changes and water testing, or the feeding of possibly better food than I eat myself--I am just getting frustrated at my little buddies dying and want to be a good goldfish steward. Thanks for any help you can give me, Kate <Hope this helps, Neale.> Goldfish chasing after meals 2/1/09 Hi guys, It was really interesting browsing your website, great stuff! I have a comet and a common, about 8 cm each, in a 25 gallon tank. They seem to get along pretty well most of the time, schooling and stuff, but every time I feed them, the common will chase the comet around the tank for maybe 10 minutes afterwards. Any other time of the day, they're fine with one another, it's just after mealtimes that the common decides to bug the comet. I feed them two small meals a day, just enough that they finish in under a minute, so I don't think it's that they're hungry. Any ideas as to why he chases after feeding? Thanks a lot! Katie <Hi Katie. There's an assumption that fish in schools are mindless. They're not. Although we don't see it, schooling animals are constantly engaged in pretty intense social behaviours, jockeying for position. My metaphor for explaining this is (unfortunately) based on my niece and her high school career as a cheerleader. From the outside, the girls all formed a coherent team, but spend any time listening to them, and boy, it was knives out! Constant battles over who was the head girl, which girls were her lieutenants. Just the same in a school of fish. What you're likely seeing is nothing more than energy being spent as the Common (what a poor name for a beautiful fish!) Goldfish chases the Comet, asserting his (or her) dominance in the pack. It has to be said that schooling fish tend to settle down best in big groups, and when kept in twos or threes there's always a risk of bullying. So watch out. Cheers, Neale.> Re: Goldfish chasing after meals 2/1/09 Hi Neale, Thanks so much for your reply, it certainly seems like he's just jockeying for dominance now that I think of it. Oh and I totally agree that 'Common' is a terrible name for such a cute fish, his real name is Oscar Shakes and my Comet's name is Captain Chance. Have a great day :) Katie <Glad to help. For what it's worth Common and Comet Goldfish are easily my two favourite varieties, and surely among the best aquarium fish out there. If Goldfish sold for $500 a piece instead of 50 cents, I think people would appreciate them a lot more. They're just as pretty as any Arowana, and ten times smarter. Since it's half-past ten in the evening here in England, you mind if I take a rain-check on the "great day" and leave it for tomorrow? Cheers, Neale.> Fantail behaviour. 01/20/09 Hi, <Hello> I currently have a 190 litre tank, there is more than enough room, air, live plants and bogwood for all of my fish. I have 4 Fantails, 3 of which are the problem, My biggest on (scar face) is approx 10 inches long, the other one (spot) is approx 7 inches long and the smallest one (sparkle) is approx 5 inches long. There is a 4th fantail (sharky) and it's about 8 inches long. <This volume... less than 50 gal.s, minus displacement for gravel, wood... is insufficient space for this much goldfish flesh...> The problem is with the first 3, Scar face and Spot seem to be bullying sparkle, she is small anyway but this consistent...what seems to be battering, is weakening her. It seems that they're both in cahoots and both go at her at the same time. I've had all 4 fish together for a long time, approximately 12 months and there has always been a bit of chasing about, but within the last 3 or 4 days it seems to have become violent. Is she in season and the bigger 2 are competing or is it a case of bullying? <More likely "season"... though it could be a case of bullying as well> If it's bullying, what can I do about it? <Separate them... with a divider... and start looking for a much larger (at least twice the size) system> I can't let them kill her. Thanks K. Ashton <Welcome. Bob Fenner> Goldfish mouth is all yellow 1/17/09 Hi, I just noticed one of my goldfish is yellow around the mouth and my comet's tail is partly yellow. Is something wrong? Thanks. <Mmm, likely nothing is wrong here... Some goldfishes do have, accumulate a distinctive yellow coloring in these areas... Likely just genetic expression. If all else appears fine... health- water-quality wise, I would not be concerned. Bob Fenner> Introduced new fish, goldfish beh.
11/24/08 Goldfish swimming abnormally 9/29/08 Help... Fancy goldfish... beh./hlth. 8/21/08 Hi, I bought my Son two Fish (Fancy's) last week. One of them have has a long brown stringy something!!! (looks like poo) hanging from its behind, and measures roughly about 3-4cm long. Could you please let me know what it could be, and what I should do, as my Son is very worried. Thanks Claire <Claire, what you are seeing is a symptom of constipation. The "strings" are compacted faeces. I'm guessing you are feeding this fish Goldfish flake. Contrary to what you might imagine, this isn't a good diet for them. They need lots of green foods; please read here: http://www.wetwebmedia.com/FWsubwebindex/gldfshmalnut.htm Short term there's nothing to worry about, but long term constipation makes Goldfish much more prone to serious diseases and problems. Do also make sure you understand what Goldfish need to thrive. Too many people buy them without researching their needs, and consequently a miserably high proportion either die or have grim, short lives. Say "no" to bowls and small tanks, and "yes" to big tanks, green foods, and good water quality! See here: http://www.wetwebmedia.com/FWsubwebindex/goldfish101art.htm Cheers, Neale.>
Goldfish... sys. -- 07/10/08 Hello crew, I have seen a lot of similar questions about peoples' goldfish, but I wanted to make my goldfish's symptoms more specific. He was fine a few days ago, but now he just lays down on his side or stomach on the bottom of the bowl. And it looks like he's making an effort to try and swim but only one of his fins is moving, so when he swims its almost like he's uneven. For example, when he tries to go up near the surface of the water only one fin will move and this causes him to twirl around or something like this. He still seems very aware as well, if my sister or I go sit near his bowl he comes over and sits closer to us. Every once and a while when he goes to the surface it looks like he's a bit better, but its almost as if he gets tired really quickly and just goes back to lay down. Any help would be greatly appreciated. Thank you, Lee <Hello Lee. The problem here is Goldfish do not live long in bowls. Forget everything you have seen on TV. Bowls are "goldfish killing machines" and most die within months of being placed in them. You absolutely must keep Goldfish in an aquarium. Juveniles will do well in tanks around the 75 litre/20 gallon size, while adults (which reach 20-30 cm/8-12 inches in length) invariably need something larger, around 125 litres/30 gallons being a good choice. In bowls they slowly get poisoned by the ammonia they produce, and the lack of oxygen in the water suffocates them. Please also understand Goldfish are sociable, and should be kept in groups of at least two specimens. But don't under any circumstances add another one to your bowl! Instead, read this article on Goldfish care, and then go buy an aquarium no smaller than 75 litres/20 gallons. http://www.wetwebmedia.com/FWSubWebIndex/goldfish101art.htm Otherwise your Goldfish is doomed and will die. Hope this helps. Cheers, Neale Re: goldfish 7/10/08 Thank you very much for all the advice. My fish is doing much better today, I'm not exactly sure what happened. I will definitely buy an aquarium. Thanks again! Lee <This sounds promising. But please don't delay buying an aquarium for too long... if I was you, I'd put it on my "to do" list for the weekend. And don't waste your money on a little 10 gallon system. For Goldfish, you need a fairly big tank because they grow very quickly and make a lot of mess. Cheers, Neale.> My zippy goldfish, pond 7/4/08 Hello - I have been reading your threads, hoping to find an answer to my very simple question... <Did you?> I purchased two "feeder" comets from my LFS approx. one month ago. They currently live in a 40 gallon pond on my deck with several water lettuce, water hyacinth, a vigorous water lily, some parrot feather, moneywort and a hornwort plant. <This is a lot of plant life for such a small volume... likely shifts water quality a great deal... too much, diurnally> I made a filter for them from things l had at hand, and it seems to be working like a dream. The filter/pump empties into a small fish spitter and the little eco system seems to be working quite well. I do a 10% water change once, sometimes twice a week (I use the pond water to water my container garden on the deck), have put a few barley pellets in to keep the algae down (so far, I haven't seen any, at all) and my pond gets about 6-8 hours of sunlight a day. I feed my two gold fish one tiny little sinking pellet a day (they are only about an inch in size, each - but have grown a 1/4" since I got them!) and they seem to be doing well. They especially seem to enjoy hanging out among the roots of the floating plants. My spitter sits on three concrete blocks, which also provides some shade/hiding spots for them. <Sounds good> My question is - when I do see them out from under the plants, they are SUPER zippy. They swim about at an accelerated pace, and I'm wondering if they are a bit stressed, or afraid when they are not under cover. The only time I have seen them slow down is when they are nibbling the worst or nibbling at their food. Although one appears to have grown a bit larger (and I'm thinking its female) and will often push the other around when there's food, they follow each other about the tank and tend to "hang out" under the plants together. I do not have nitrate or ammonia testers, but I do test the ph (its currently at about 7.5-8.0) <This is too large a "swing"... In part what I alluded to at first> These are my first fish (I plan to have a 100 gallon pond for them for next summer when they get a bit bigger), and although I've quite enjoyed the research I've conducted so far, I want to make sure they are doing well, have fish-happiness and are healthy. <I see> Thank you for your assistance. -Leanne (and Hugo and Zero) <Well, the "zippiness" may be nothing to be concerned about. With warm/er water conditions, goldfish tend to be more active. As long as they are eating, appear fine otherwise, I would not be concerned. Do keep up with those weekly water changes. Bob Fenner> My goldfish is flipping out 7/3/08 Hello! <Hello indeed!> New here! <Welcome!> We had two goldfish for about 3-4 weeks. This morning, one was dead. I took him out immediately, checked the filter (looked like it needed to be replaced and so I replaced it), and cleaned the tank. <Be careful here; replacing all the filter media will re-cycle your tank> The fish that is alive has been swimming super-fast all over the tank...not upside-down at all. He swims back and forth, up and down...almost like he is trying to come through the tank. <He may well be trying to escape...toxic water conditions> He also seems to swim in the front of the tank, not in the back at all. His mouth is gaping very very often as well (I don't recall it doing that before). I've put some food in the tank but he doesn't go to the top to eat it as he always has. I noticed him this evening picking at the bottom of the rocks. I don't want him to die either. I feel terrible about the one dying (they were a gift for our daughter when she learned to swim underwater). We are not ready to replace the other fish if this one isn't going to make it and continue a death cycle! Here are some specifics: 2.5 gallon tank (I know now after reading other posts), <In this case rather than replacing a fish, consider replacing your aquarium. A goldfish needs at least 15-20 gallons to prevent rapid build-up of nitrogenous wastes, and swimming room, etc.> whisper filter- medium, he doesn't have cloudy eyes nor does his body look damaged or discolored, the food we have is Wardley Goldfish Flake food, <Do read re goldfish nutrition on wetwebmedia.com; this food will not suffice in the long term.> I have not tested the water (didn't know about that until reading some other posts), he is about 1.5" long and I did not attempt to give him a minced pea. <The pea is a laxative, generally. Vegetable matter is always appreciated by goldfish, though. I would recommend purchasing some test kits if you wish to continue with aquaria- avoid the dip strip variety, as they tend to be of widely questionable accuracy. Also continue to do some reading on WetWebMedia re aquarium husbandry, water changes, feeding, etc.> We are not familiar with caring for goldfish and thought that it wouldn't be daunting aside from feeding them and cleaning the tank. With one dead, I want to make sure the other one doesn't die because of something I did wrong. <Understood. Many of us come in to this hobby without the faintest of what we're doing- who thought keeping ecosystems in glass boxes could be so complicated, eh?> Any advice you can give is greatly appreciated. I read lots of posts before bugging you so I apologize if you answered this for someone else already. If you have, do you have the direct link to that posting? <I would just use the index to find some of the pages on basic freshwater aquarium keeping. Do a few small water changes on your goldfish's tank to keep him alive in the meantime, and research, research, research before setting up an appropriate aquarium for the fish you and your daughter ultimately wish to keep. You will find the time and money invested will repay you thousandfold times in enjoyment and health- both for the fish and your sanity!> Many thanks for your time and consideration, <No problem, Lisa. Why don't you drop by our forum at bb.wetwebmedia.com as well; many knowledgeable people there who would no doubt be happy to answer setup questions, product questions, etc as you continue on this odyssey> Lisa <Benjamin> Re: My goldfish is flipping out - 7/3/08 7/7/08 Hello! <Hello again!> Thank you for your speedy reply! I meant to update you earlier than this on the goldfish. He seems absolutely fine now. Perhaps I was freaking myself out about his behavior being that I haven't own fish in 16 years (and that was one angel fish and two kissing fish). He hasn't been swimming at the speed of light and is now using the whole tank (I use the term "whole" loosely being it's small). Maybe he was freaked out that the other fish died. <Glad to hear things have calmed down> He is IN LOVE with peas. I gave him a little bit of one pea one night and he couldn't wait for more! I also bought some sinking pellets. I saw him swim immediately to eat one but spit it out just as quickly. I'm not sure if that is because it's too hard. I don't see them the next morning which makes me think he waited for them to soften before eating them (does that make sense?). <Goldfish are quite fond of their veggies. Check information on wetwebmedia.com, or ask for recipes for goldfish foods on our forum at bb.wetwebmedia.com to learn how you can produce your own nutritious, economical foods for your fish that he will relish as much as the peas> Anyway, I know you said peas are a laxative to fish. Does this mean he should not eat them regularly? He really loved the pieces I put in the tank and if he can eat peas regularly, I am happy to give them to him (or other vegetable matter). I'm going to look at the area of your site you recommended to see if the answers about peas and other vegetable matter is discussed there. <Yes, information about goldfish nutrition is available> I'm asking the questions in more of a rhetorical form...however if you're looking for a way to kill a few minutes and want to reply, that's fab too! :-) Thank you so much for all of your advice and your website!!! <You're most certainly welcome> Lisa <Benjamin> My Oranda's very strange behavior 6/27/08 HI, My name is Whitney. I have a 30 gallon tank operating on a TopFin filter system. I have always kept Oranda's in the tank with a couple of plecostomus. I was having some trouble with the fish, and discovered that all of my toxicity levels were off, <What do you mean by this?> so I started over with the tank. Once it was clean, cycled and all toxicity levels were back to normal I purchased a new Oranda. He is small but quickly adapted to the water. A week later I purchased another one, but this one is about 3-4" long (our small one is about one inch). At first the small one was a little scarred, but in no time they were both doing great, in fact they seemed like friends. I then noticed that the plecostomus was being aggressive towards the large Oranda <Happens> and had removed a couple of scales, so I immediately removed the plecostomus and put in some MelaFix to help the fish. <This may arrest biological filtration> Once he got better I did some water changes to get the MelaFix residue out and ensure that all toxicity levels were appropriate. I test the water frequently, and with the exception of the hard water here in Las Vegas, everything checks out perfectly every time. So here is my problem.....the large Oranda, who prefers to eat sinking pellets, and loves them, apparently also loves to do headstands. <Mmm, not good> He does not float, sink or have any problem swimming, but he likes to put his face against the pebbles and stick his fin in the air, perfectly vertical. At first I just figured this is how he sleeps, but now it is happening very frequently. When he chooses to swim, he swims fine and looks good, but he rarely does. The other fish is perfectly fine, and often lays next to the other on the bottom of the tank. There is still no aggression, no other signs of a problem, and all water toxicity levels are perfect. I don't know what to do and it seems to be very strange. Anything you could tell me would be great. Thank you! <This sort of "gas bladder" anomaly can be due to "just" genetic disposition, but is very often linked to improper nutrition. Please read here: http://wetwebmedia.com/FWSubWebIndex/gldfshmalnut.htm and the linked files above... BobF> Calico fantail goldfish fighting, env. 6/24/08 I had four calico fantail goldfish in a 10 gallon tank for about a year now. <Need much more room... had you read...> One of them had been sick for a long time, and eventually lost his tail? <Env.> And died about two months ago, leaving me with three in the tank. Recently, I have noticed the two bigger fish bothering and pushing around the fish who is a little smaller natured. I immediately felt bad and put the small fish into a separate, 2 gallon tank, which is way too small. <Yes> I was wondering if it was common for fish to do this? They have been living in the same tank for a year, and this just started happening. Should I try and put him back in the tank with the other two? <Due to crowding mostly... likely nutrition secondarily. Read here: http://wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm They, you need a larger world. Bob Fenner> HELP! Black Wen going see through! 6/10/08 Hello, <Howdy> I am in need of some professional advise asap! I have a forty gallon tank with a 60 gallon filter with four fancy goldfish. One of my goldies is a panda Oranda with a black Wen. A couple days ago I noticed his Wen was becoming see through and I could see some red underneath the flesh of his Wen. It has slowly gotten worse and now a lot of his Wen is now see through. I searched and searched but could not find anything that would cause this. In a panic I went to the LPS and I bought some anti-parasite medicated fish food and parasite clear tabs and the ladies said I could use them together. My gut said to only use the food so that's all I've done tonight as I have an off feeling about using both at one time. Any suggestions would really help! Thanks! <Mmm, this loss of coloration in hoods is actually not that uncommon... is NOT pathogenic... I would remove whatever medication you're using... pronto... by water changes, carbon use... as this/these are more deleterious than useful here. Many such instances are simply a matter of genetic/developmental expression... and will pass (re-color) or not depending on deterministic principle/s and environment... Otherwise, optimizing water quality, reducing metabolite build-up and maintaining good nutrition is all that can be done. You are not likely to find much detail re this condition on the Net, but there are references to it in good books on fancy goldfish culture. Bob Fenner>
Goldfish sitting on the bottom!? 6/3/08 Hey everyone, I have a 30 gallon goldfish tank with two stunted comets and two fantails (I wrote in a question a little while ago about the stunted fish, and you guys were great. I'm really sorry for bugging you again). My question is about one of my fantails. He was sold to his previous owner as an Oranda and was kept in a filthy ten gallon with five other fish. I've had him for about seven months and in that time he has not grown at all. He's about an inch and a half long, with no hood, huge eyes, a funny shaped body, a bent back, and two dorsal fins (or one that was split, I can't tell). Kind of a funny looking little fish. Although odd, he has always been one of the most active of my goldfish, always cruising the tank looking for food. For the last couple of days he hasn't been nearly as active. He just sits on the bottom of the tank for a couple of hours, then gets back up. In fact, he is spending more time each day laying on the bottom. He is not gasping, his fins are up, and is eating regularly. I'm wondering what is wrong with him. I had another fantail a couple months back that exhibited the same behavior and ended up passing away. All of the other fish are normal, happy and healthy. I just did a 35% water change and he is still spending a lot of time laying on the bottom. <Mmm... this sitting... is not a good sign> I just checked the water and the ammonia and nitrites are at 0ppm. The tank gets a 30-50% water change once a week. <Good> They are fed a small amount of pellets twice a day, as well as treats like romaine, brine shrimp, and marine algae. Any help would be wonderful. He may be funny looking, but he's a great little fish. Also, I have an African cichlid tank (lake Malawi). It' gets a 25% water change once a week. Right after the change, I notice a spike in the aggression among my fish. They go at each other for a while and then calm down, especially my largest male. By night time, they all have at least one rip in a fin or a missing scale. Is there any way I can cut back on this spike? By the time they all heal, it's time for a water change again! <Good observations and relating... I do see the same behavior in/with my African Cichlids and water changes as well. The goldfish I suspect are having trouble with gas exchange... basically a lack of oxygen... Likely due to increased temperature with the warm season and a "coating" of oil on the surface of the water caused by foods... I would add aeration/circulation, particularly something that will disrupt the surface (like an added outside hang-on power filter).> Thanks so much! Jessica <Welcome. Bob Fenner> Stunted goldfish questions. 5/28/2008 Hi everyone, First off, you maintain a wonderful site here. It's been amazingly helpful. <Ah, good> I have a 30 gallon tank with two small comet goldfish and two fantails (one pom pom and one small, very odd looking Oranda). The tank has 0ppm ammonia and nitrite and gets a 30% to 50% water change once a week. <Very good> They get fed a small amount of pellets twice a day, as well a treats like romaine and brine shrimp occasionally. All my fish seem active, happy, and healthy. <The best> My question relates to the two comets and the Oranda. Their previous owner kept them in a ten gallon with three other goldfish. The water was changed very infrequently and I can only guess at the state of the water quality. Needless to say, it wasn't very good. When I got the three goldfish, they were about and inch and a half long. I've had them in the 30 gallon for about six months, and the only thing that has grown is their tails. They have not put on any weight or length. I was wondering if they ever would? Do you think they were stunted? <Is indeed possible. I have encountered both situations... in which previously "challenged" goldfish (et al. species) did not grow much further at all, and where they did resume> I am in the process of setting up a small pond in my backyard that I would love to put the comets in, but I worry about leaving such small goldfish outside. <Mmm... not likely a problem. And if anywhere, they will resume growth in a pond setting> Also, one of them sometimes gulps at the top of the tank. <A natural behavior. Not to worry> Like I said, my ammonia levels are at 0, and none of the other fish in the tank ever do this. Do you think his gills were damaged by the time spent in a dirty habitat or am I just over reacting? <Perhaps a bit of both> I've gotten way too attached to these little guys and any advice would be wonderful. Jessica <You're doing fine... Enjoy your aquatic charges. Bob Fenner> Don't understand my goldfish's behaviour and... Reading 05/23/08 Hi, I have been looking for answers for a few days now and I think yours is the site to help me. I have a small tank 20 litres tank with 4 small ( 2" maximum length) goldfish in it. <... needs more room/volume...> Before these little guys I had 3 large ( 4"fish ) and they were doing really well, never any problem, but were too big so I found them a new home. <Good> Now my small fish, whom I thought would do better, due to the fish / water ratio are poorly. 1 of them stays all the time in the plant we have , head down, hardly moving but comes up for food. No idea why it is doing this, could it be spawning , or trying to spawn ? <No...> Secondly, 2 of the fish have a milky, mildewy look to their skin and their tales are shredding ( the skin between the 'ribs is disappearing ) and they can 't swim very well as a result. What could this be and how do I treat it? <Environment... water quality...> Any help and advice is most welcome as I am attached to little beasts. Thanks in advance Susanne from Portugal <Read here: http://wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm and the linked files above. Bob Fenner> Odd behavior 5/16/08 My son has two regular/feeder goldfish. We have had them for 3 years. One has grown very large, and the other one has only one eye (It came this way from the store). Both are very interesting and enjoyable to watch. Three days ago, the large one started picking up a rock, that is about 2 inches around, and "throwing" against the tank. Some facts: he has always picked up gravel from the bottom of the tank and spit it out, never "throwing" it against the tank. The tank is 55 gallons. The fish get fish treat pellets and regular goldfish flakes. Nothing has recently changed (tank cleaning, moving, food, etc.). The first day this behavior started my husband eventually moved the rock. The next day that rock, in addition to two more rocks, were back to the corner of the tank where he continued to "throw" the rock. This goes on throughout the day. I want to know why he is doing this? Does he enjoy it? Is he bored? Is he nesting? The one eyed goldfish just watches and swims around him. The big one also often chases the small one around the tank. Help. I would hate for anything bad to happen to these fish. They truly are like family, they have been with us for so long. <Greetings. Nothing to worry about here, though very, very odd for Goldfish. Cichlids are notorious for their landscaping abilities, and will often move surprisingly large amounts of sand or pebbles about the aquarium. Goldfish don't build nests, and normally scatter their eggs about during a rather frantic spawning dance through the plants. Contrary to myth, Goldfish are relatively smart animals, and widely used in animal behaviour experiments. So this may simply be a "play" behaviour of some sort, or perhaps a displacement behaviour. Your tank is nice and large, but you might consider adding some big plastic plants (tall ones, ideally) and perhaps a few rocks so that the fish have places to explore and investigate. In addition, you might try hand-training your fish: this teaches your fish to interact with the people outside the tank (by begging for food, usually!) and also you can try feeding them in a more fun way, moving food about so they have to chase it or swim to the top. Anything that makes life more fun is a great idea with large fish, because they often are quite smart animals. You could also add a couple more Goldfish: the more pals they have, the less bored they'll be. Cheers, Neale.>
My Chameleon fish, Goldfish colour change/beh. 4/13/08 Hello, This is more a general enquiry than a worried owner. I have two fish one Oranda and a Fantail, we've had then for round a year they live in a well maintained 40L tank and appear to be extremely happy with gorgeous colouring. When I bought them the Oranda (George) was a beautiful coffee brown colour all over and the more lively and playful (bordering on annoying George) Fantail (sharky) was a vibrant orange with a brown stripe down his back and brown lips....However now the fantail (sharky) has lost his brown stripe but remains orange with brown lips, whilst my Oranda (George) has completely changed his colouring he is now? orange with brown lips exactly like his partner in crime sharky....Is this normal??? Thank you Bea <Bea, It is quite common for Goldfish to change colour. Provided the fish is otherwise in good health and doesn't show any signs of background problems like split fins or excessive mucous production, I'd not worry about it. Cheers, Neale.> Goldfish behaviour problem... env. 3/9/08 Hi WWM Crew! My name is Nikola and I'm writing to you from Belgrade, Serbia. Thank you for your help in advance! <Welcome Nikola> The problem is this: I got a fish tank for my birthday (20 litres) and a goldfish (a little one by the way), now I know it is a small tank, but it was a gift so I kept it and bought 2 more goldfish (from the same tank in the store-fantail all 3). <These fish need more room than this my friend> After a while the 2 new fish seemed to get along extremely well with one another but not so well with the little one. At first, after feeding the 2 used to get really hyperactive, searching the pebbles for food and used to chase the little one away. Then they started chasing it. Little by little it got really aggressive, they seemed to be pushing it around hard. Now I don't know if it's because of them or did the little one get fin rot, but he got sick and died. Now I bought a new fish (also fantail) and now they're aggressive toward it too. Can they truly hurt it? <Yes> What should I do? I would appreciate it if you could answer me to my e-mail. Thank you! <The agonistic/aggressive behavior is largely due to crowding... These goldfish need much more room...

Bob Fenner> Goldfish swimming in formation 3/7/08 Hello, I stumbled across a video of 4 goldfish swimming in formation, and responding to hand signals. I am skeptical that fish can be trained in this way. Here is the video: http://www.youtube.com/watch?v=Qbei8_tRNS8> Jeremy <What a hoot! BobF> Redcap- goldfish, colour fading 2/9/08 Hi This is the first time that I have ever asked for advice online. <First time caller!> I have a large tank with a variety of 6 goldfish ranging from 4 to 2 years old. One of my fish is a red cap with pot belly fish ( not sure if that is the correct terminology). <Proper terminology is likely something in Mandarin or something... but anyway.> I am guessing it is around 3 and a half years old and has a very thick raised cap. That changed about a year ago. About 4 days ago I noticed that the red cap was fading in colour. <Does happen, usually because of excess mucous (grey stuff) or fungus (fuzz) covering the "cap". Usually a sign of water quality issues, e.g., inadequate filtration, over-feeding, or insufficient water changes. In any case, your first task is to do a water test for nitrite.> Prior to this it was a nice deep orange red. It now has patches with the colour missing and in fact it almost seems transparent. Is this normal, aging or is there something I should be doing to help it? <Certainly NOT normal, no. Sometimes genetics can be at the root of the problem, especially if water quality appears to be good and all the other fish are in sparkling health. But if the "cap" is not only losing colour but also exhibiting a change in texture or has visible signs of mucous, rot, or fungal infection, then genetics aren't likely the key factor.> thanks for your help, Lyn <Do read here: http://www.wetwebmedia.com/FWSubWebIndex/gldfshdisease.htm Cheers, Neale.> Goldfish lack of growth 2/7/07 I have perused the goldfish FAQs but have not found a response to my question yet. I have chiefly planted tropical tanks, but in our living room we have 2 goldfish. One is a calico Ryukin, the other (we think) has some Wakin and some Comet in him... he's got a Comet's finnage and a Wakin's body shape. They're in a 29 gallon tank, which is lightly planted with some Anubias and Java fern. There is also a small algae crew in there... largely Taiwan Blue Shrimp (Neocaridina denticula sinensis.) <Sounds very nice> We use an Aquaclear filter which circulates around 350 gph. We feed our goldies Hikari Oranda Gold as a staple, which we soak for 3 minutes before feeding. They also get frequent fresh snacks including duckweed, Riccia, Water Sprite, lettuce, spinach, zucchini, tiny bits of baked squash and yam...in short, lots of veggies. The water comes out of the tap at about 8.0; we (religiously) do 20% water changes 2x weekly. We don't really have any floating problems. We've had them for over 6 months,! and while they seem healthy and active, I'm just not seeing a lot of growth, and I'm wondering why. Am I not feeding them enough? <Mmm, maybe this... could be a lack of useful nutrition... might be a metabolite feedback issue at play here as well. But, in all desired forthrightness here, I would continue as you're doing... Much better for your goldfish to (apparently) grow slowly and live long, healthy lives. They will seem to grow more during the summer> They don't look underfed, they're just not much bigger than when we got them. I'd estimate that they're about each about 2.75-3 inches long not including the caudal fin. Any advice is appreciated. Thanks! Rus Wilson <Mmm, again, if it were me/mine, I'd continue as you're doing... If you want to speed their growth, higher percentage water changes weekly, dropping the pH (likely through blending in some "cleaner" water... with less alkalinity), adding a bit of higher protein foods... will do this. Bob Fenner> Goldfish help - 1/24/08 Hello, I'm hoping you can help. 3 days ago my goldfish all of a sudden started swimming strangely. Its like it can't keep control of its right side and has begun swimming on its side, every so often going in to spinning when it tries to swim normal. Its eating habits haven't changed, but it does have problems getting to the food and has to try and come down on top of it to suction it up. I did notice a red line on its right gill, though I don't know if its a scratch. He rests either completely on his side on the bottom of the tank or tries to prop himself up against a plant. The symptoms have gotten progressively worse, where he has very little control of the swimming. And every so often he starts getting a curve in him towards the right. Though the worse symptoms are in between spurts when he has a little more control. So the "bad times" keep getting worse I should say. The tank is a 5 gallon Aqua-Tech 5 with a carbon filter. I tried to doing research and immediately changed out a third of the water and changed the filter. I also stopped feeding him for a day and gave him skinned cooked peas yesterday and today just in case it was constipation. I put in a Mardel LiveNH3 detector yesterday, and its stayed at the safe color. Today I got a Mardel 5 in 1 test strip. Nitrate was at 40, Nitrite was at 0, Hardness was at 250, Alkaline was at 180, Buffering was at 120, and the pH was at 8.0 I also started Jungle Fish Care's Lifeguard All-In-One Treatment for external fish diseases (bacterial, fungal, viral, parasitic). Its a 5 day treatment. I'm attaching a video <<RMF could not open>> I took with my cell phone of the fish, so you can see how it's behaving. Hopefully this is enough info, and I appreciate any help. Marty <Hello Marty. The usual reason Goldfish swim poorly is constipation, caused by poor feeding. When Goldfish are given flake food day-in, day-out, they often become constipated and this messes up their buoyancy. See here: http://www.wetwebmedia.com/FWSubWebIndex/gldfshmalnut.htm Looking at the video though, your fish may be constipated, but I suspect something more serious, either poisoning, bad genes, or a systemic bacterial infection. Poisoning is surprisingly easy to do: things like paint fumes, bug sprays, and other organic chemicals we use around the house are toxic to fish, and in small tanks especially they can quickly reach concentrations that harm or kill fish. I've done this myself by accident, and the death-throes of the fish are rather similar to what your Goldfish is doing. Bad genes is something we find difficult to spot when shopping, but suffice it to say that a lot of fish breeding on farms is for quantity rather than quality, and a certain proportion of the fish produced are sub-standard. Swim bladder problems are very common deformities in these fish, and that's what might be going on here. Still, if the fish was deformed in some way, I'd expect it to have always swum badly, rather than suddenly losing swimming ability. The third option is a bacterial infection. Aeromonas and Pseudomonas bacteria are harmless in healthy tanks but in tanks with variable to poor water quality they can cause all sorts of problems, one of which is a systemic infection including the swim bladder. Consequently, I think the 5-in-1 treatment is a waste of time. You need something antibacterial or antibiotic. Maracyn-Two is the usual antibiotic recommended for this, but (as far as I know) it is only traded in the US. If you're outside the US, then you might be able to use an antibacterial such as Interpet #13, but in all honesty these tend only to work with early to mild infections, and your fish is so sick that you'll likely need to get a prescription antibiotic from your vet. I am somewhat concerned that this fish is being kept in a 5 gallon tank -- this is completely inappropriate for Goldfish, and while unlikely the immediate cause of the problem, such a small tank won't be doing anything to help the fish either. Small Goldfish can be kept in 10-20 gallon tanks, but once they get above about 8 cm/3", they really need something around the 30 gallon mark. Cheers, Neale.> Re: Goldfish help - 1/24/08 Hi Neale, thanks for the response - Is here anything to be able to tell for sure if its this [chemical fumes, poisoning], or anything that can be done if it is? It has a closed lid and the tank sits on a serving window (that opens from the kitchen in to the living room (we live in an apartment). So it sits elevated with the sink behind it, and doesn't really get anything around it. <No way to test. Cooking smells and steam generally aren't dangerous to fish. But certainly cleaning chemicals might be if they got into the tank. It's really a case of common sense -- is it possible anything got spilled into the tank? Sometimes children and house-mates "accidentally" put things in fish tanks, such as beverages.> Yes, we got him in June and this just started happening a few days ago. >I agree, bad genes doesn't sound likely.> What about something like Fish Mox (Amoxicillin)? <No personal experience. Amoxicillin can be used against Aeromonas, but some strains of Aeromonas are Amoxicillin-resistant, so your results could be less than perfect. Definitely worth a shot though if you have some lying around. But I think Maracyn-Two has a better reputation for Swim Bladder infections, so if you haven't spent the money yet, I'd try that one first.> Well, it doesn't make sense to look in to changing the tank size until I find out what's wrong and treat it. 30-gal tanks are a bit expensive for me (average of $200 on up), especially to spend on a single goldfish that might be dying anyway. Marty <Put simply, in a 5 gallon tank, Goldfish health is never very good. Even if you get the right medications, this fish might not recover when kept in such a tank. Fish kept in such small tanks are always more likely to get sick, and less likely to recover, simply because small volumes of water are less stable and more rapidly polluted than big volumes of water. I agree $200 (US) would be an insane amount of money to spend on a 30 gallon tank. But you should be able to get a basic system for much less than that. If you're saying to me that if this fish dies, you won't ever keep fish again, that's one thing, and I can understand your reticence over spending more money. But if this fish dies and you go straight out and buy another fish, that's not acceptable. It's not fair on the fish, condemning it to a grim life in a stagnant puddle of water; and it's ultimately not fair on you, because you'll sooner or later have to deal with another sick fish. Your move. Cheers, Neale.> Aggressive goldfish... just too crowded, not reading 1/7/08 Hello! I'm KJ! First of all, thank you for having such a helpful site, I have really learned a lot from it! <Ah, am glad KJ> I have a question about my crazy goldfish (they aren't actually crazy, it is probably more that I'm crazy about them). <Insightful> Anyway, I rescued two goldfish, a comet and a fantail, from my swim team's coach's office over the summer. I became very attached to them, and wanted a better home for them than a small bowl. I don't know exactly how many gallons were in the bowl, but I *know* there was no way any number of fish should have been in it. So, for a Christmas present, my parents gave me an Eclipse 12 Gallon tank (Yay!) that I planned on moving my two lovely fishies into. However, a week or so before Christmas, I noticed symptoms in my fantail that resembled dropsy (I've had a beta fish die from it as well). I tried to help him/her, but I think it only extended his life a little. Sadly, he died on Christmas Eve. So I set up my new tank on Christmas morning, and my parents were ready to move my yellow fishy, as I call my comet, into his new home. I made them wait three days to let the tank mature a bit, because that was the time most people suggested. <Need more time than this...> Before I woke up on the 28th, my parents ran out to Petco to surprise me and bought FIVE new fish, 3 more comets (all very small, about 3/4 o f an inch), a red-cap Oranda, and a calico fantail. The largest fish in the tank is yellow fishy, my old comet, but only by about a quarter inch. <Yikes... the 12 gallon isn't large enough for one goldfish in time...> So the whole point of that story is that today, I was procrastinating from my homework and watching my lovely fish when I noticed that the calico fantail had the uppermost right tip of its tail missing. It doesn't look like rot, I already checked that out, but it looks like it was cut off. At first I suspected the pump that draws water into the filter, but I looked into my tank with horror as my beloved yellow fishy was nipping the fantail! <Yes... too crowded> So, I have removed yellow fishy, and put him in his bowl (only temporarily, of course). My main question is, however, even though there are too many fish in one tank, why did my yellow fishy only go after the one fantail? <Crowding... easier target> And he has more room than in the bowl with my old fantail?! How should I deal with my yellow fishy and my calico? He really just ignored the other fish in the tank, but he chased the poor fantail... Oh, and should I treat the calico's tail? <Mmm, indirectly... by making more room...> In some earlier responses, it says to treat for fin rot, but others say just to watch it and keep the water clean. I really hope I haven't wasted your time and I appreciate your response. Why can't we all just get along? :) KJ <For about the same reason/s... Please read here: http://wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm and the linked files above. Please follow directions and look before writing us. Bob Fenner> Re: Aggressive goldfish... lack of values 1/8/08 Thank you for your prompt response, but I believe you misunderstood me. I know and understand that there is not enough room in my tank for so many fish. I guess I did not make that clear. However, I did not buy my fish, my parents bought them for me. <... I understood/stand this... nonetheless... what will you do?> As four of them were apparently only 29 cents, I would feel stupid asking to return them. In addition, I did not buy my tank, it was also a gift, because I only have a summer job as I am still in school. <... impertinent> My question was more along the lines of why my fish disliked only one of his tankmates, not whether my tank was too crowded or not. <It... fishes... don't dislike anything (at least to my perception), but many are rather autistic... do "pick" on things that are "in the way"> I did read your site, I know I have too many fish, but I cannot do anything about it at the moment. <Then your fish will suffer and die> Also, most questions that involved aggressiveness in goldfish involved multi-species tank, and I have only goldfish. In an email dated November 25, 2005, it was the opposite situation, with a fantail bullying a comet, but they did not mention tank size. I find it slightly offensive that by providing more information I received a rude reply with no answer to my question. Again, I still like your site, and maybe you were just in a bad mood. *I really just want to know how to keep my fish safe*. I cannot afford a larger tank, and I do not want to offend my parents by asking them to return my fish. <... then... see the above. RMF> Goldfish behavior...please help 1/5/08 Hi there! <Hello,> I'm not quite a fish brainer, but I've read a little bit about fish and their breeding, specially mine. <Very good.> I have a 42 gallon tank and I have a red cap and an orange fantail. Today my orange fantail began chasing all around the tank my redcap and I supposed well, it's a common behavior and then I looked for the male tubercles but I couldn't see them. So my question is, can the tubercles appear later? or are my 2 fish are males? <The breeding tubercles should be visible on sexually mature males in breeding condition. If you can't see them, then chances are your fish are either females or else aren't in breeding condition.> And, if they lay eggs, when I separate the eggs to another tank to avoid getting ate, do I have to provide more oxygen or with the surface oxygen is OK? <You will likely need to remove the eggs to another tank to prevent them being eaten. It's just not practical in most cases to leave the eggs with the parents. You can certainly try putting the eggs in a floating breeding trap to see what happens before you invest in a 10 or 20 gallon tank just for rearing fry (which is how experienced breeders rear baby fish). This said, Goldfish are notoriously difficult to spawn anywhere other than a pond, where they tend to breed like rabbits. In an aquarium, you need to provide conditioning foods (bloodworms and mosquito larvae for example) and then cool down the water for a few weeks (to simulate winter) and then warm it up again (to simulate spring). Goldfish spawn in the morning, and the tank should receive some early morning sunlight to "trigger" spawning.> Thanks. <You're welcome.> P.S. I don't know exactly how old are my fish cause when I bought them they where a little big, not too much but they weren't fry. And now they are quite big about 8 cm o more I'm not sure <May be a bit small for breeding still. Cheers, Neale.> Black Moor... beh., hlth. 1/3/08 Hi, I have just bought two black Moors and although one seems very happy one of them is staying at the top of the tank and the fin on his back is not standing up, also the two wispy fins that come from the body are flat to the body until he does venture for a little swim down from the top. Is there something wrong with him or is he maybe just adjusting to his surroundings? Many Thanks Alice <Hello Alice... it's difficult to answer this without seeing the fish. While fish can react badly to being moved, they should pep up within 24-48 hours. Do water tests to check the nitrite and pH especially are where they should be (i.e., zero nitrite, and the pH around 7.5). Also keep an eye out for signs of Finrot and Fungus, both quite common on Goldfish when stressed or kept under less than perfect conditions. Do review Bob's article on Goldfish requirements, here: http://www.wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm Let it be noted that the more space and better the filtration, the healthier your fish will be. It's hard to keep Goldfish happy in tanks less than 30 gallons in size and without a decent electric canister filter. Cheers, Neale.> Fantails harassing black moor -- 1/2/08 I had 2 fantails and a black moor in an outside aboveground pond of cca. 200 litres (80 gallons, I guess). As we get quite cold winters, this October, I transferred the fish in a makeshift aquarium inside (in several steps to get them acclimatised to the temperature (the garage, the screened porch than the hallway, finally the heated room). <Good... and good technique> The makeshift aquarium was about 50 litres <Needs to be larger than this...> and the fantails seemed to be harassing the black moor, so I had them separated (the black moor on its own in one, the fantails together in another. <Good> I tried to improvise the system which would cycle the water among the two aquaria, hoping that the larger amount of water would be more easily balanced. This didn't work out very well: it was impossible to maintain equal water levels, so I had run the setup with separate air pumps to drive small DIY filters. It all sent seemingly fine and 2 months later I decided to buy a larger glass aquarium (120 litres - around 30 gal), <Needs to larger...> which I set up using existing filter media and gravel, hoping that it would be better looking and give more space to the fish. When I put them together, the fantails started harassing the moor. The moor would "hide" on the bottom or upside down in the corner. I had hoped that the larger space would be enough to prevent such behaviour. <If it were large enough...> The question is: will they stop fighting eventually and If not, is it better to keep them separated in different tanks or try a tank divider. <I would first get a large/r enough system...> I really like the large tank and the water quality is great in it, so I feel sorry for the moor to be left in a small tank and having to endure larger water changes. Thanks a lot for your help. Kata <Please read here: http://wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm and the linked files above. The behavior you observe is quite common... and you do need to address it... by separation, or providing suitable space. Bob Fenner> Re: fantails harassing black moor 1/2/08 Dear Bob, Are you saying that I need more than 120litres for 3 tiny goldfish (around 5 cm)? <Mmm, no... sorry for the assumption on my part... I thought your fans would be much larger than this> I read somewhere that I need a gallon for every inch of fish and I have much more than that. <A poor "rule"... imagine a ten inch fish in a ten gallon system...> Even your "rule" of several gallons per young fish and even 10 gallons per fish still hold. How much more would you say I need? Thanks. Kata <You should be fine here after all... until these fish are much larger... in a cool (temp.) garage setting, with adequate biofiltration. I would just put in a partition to keep the gold fans from the Moor. Cheers, BobF>
Redcap Oranda problem 11/6/07 Hello, I have a red cap Oranda named snookums for about a year now and is quite healthy and just recently ive noticed the large red cap growth has grown to an extent where it covers the top of its head completely. it also has some kind of clear tissue/membrane growth by its cheeks which doesn't look like any disease at all but looks more like parts of its face... my question and concern is that the membrane by its cheeks is slowly growing and beginning to creep near its eyes. what would be the best thing or method to counter that? <Mmm, there are times, folks who advocate some sort of surgical removal... I do not... I would just wait, allow the fish to develop other senses to finding its way about, food...> ive seen a picture of it in a book (cant remember the title) where they would use a scalpel and remove the membrane quickly while the fish is out of the water for a few seconds? <Yes> I know this sounds barbaric, but they mentioned that this is the only thing that can be done to save it. <Can, will adapt as is...> this is exactly what happened to my brothers goldfish until it was too late and the fish couldn't see where it would swim too, then it just stayed in one place helpless... I really don't want this to happen to my fish, so any help would be appreciated. thanks in advance, Ryan <Try to not worry, anthropomorphize... All will likely be fine. Bob Fenner> Black Moor Behaviour 9/16/07 Hello :) <<Hello back. :) Tom here.>> Sorry to bother you. <<Bother away! That's why we're here!>> I have 3 baby black moors, 2 in one tank and 1 in another smaller tank. <<How large are the tanks?>> Of the two sharing a tank, one likes to swim around all the time and the other likes to lie on the bottom in the black rocks about 50% of the time. <<Swimming around all the time is good. Lying on the bottom isn't, even when it's only 50% of the time.>> The one in the tank by himself likes sitting on the bottom about 80% of the time. <<Trust me. He doesn't 'like' it. He's laying on the bottom because something's not right.>> They are not 'head-standing' rather just resting on their bellies in the middle of the tank. Should I be worried about this? <<Yes, you should. Do me a favor and write back with the specifics about the tanks, i.e. size, filtration, water parameters (if possible), cleaning regimen/schedule, etc. It's a good bet that your Moors are in tanks that are either too small, which is a very common mistake, or, the water conditions are out of line with their requirements. (Don't be afraid to include your name. :) ) Thank you! <<You're welcome and, I'll look forward to hearing back from you. Tom>> Weird lionhead behavior 9/11/07 Hi, <Howdy> I recently
purchased a lion head goldfish, and it has a really odd behavior. In
one particular section of my tank, it would first float vertically with
its mouth and head at the bottom of the tank, and then it would
eventually flip over and "sleep" on its side as if its dead.
It would do this for a period of time and "wake up" from its
sleep and swim around like nothing has happened. When it does
"wake up" it acts fine like nothing is wrong and continues to
swim joyfully around the tank with its other buddies. Is this normal
behavior lionheads? Or is there something wrong with it. Thanks for all
the help! sleeping fish <Mmm, like too many fancy goldfish, this
reads as if this one is suffering imbalance problems from genetic,
possibly to likely nutritional, and perhaps traumatic influences...

I've had a smooth running goldfish tank for over a year now, but a new resident is making me worry. He was a birthday present from my little sister and although she meant well, she picked a dud. Dwight, as we call him, is not a beautiful fancy goldfish. In fact, he's rather a mutant. He seems to be a cross of breeds but due to his awkward appearance, I have no idea which two. Dwight has one eyeball larger then the other, which leads to difficulty feeding, and small fins which means he has to swim twice as hard as everyone else. Although he does eat and has grown to a healthy size, he seems to have a problem with his swim bladder. Usually at the end of the day little Dwight just kind of float with his back against the surface of the water. He moves around the tank but sticks to the surface. <Not good> Every now and then he dives, but quickly bobs back up. I was worried the first few days, but every morning he's right as rain again. Since none of the other fish are affected I'm pretty sure it's not water quality, and since it's regular I have a feeling it's just a down side of Dwight's interesting physic. <Well put... Is likely a big factor here> I was wondering if this home-grown hypothesis makes sense and if there is anything I can do, changing his diet of TetraColor Sinking Goldfish Pellets or adding some kind of organic food item, that will help with his swim bladder problem. Thank you so much for your help. <Please read here: http://www.wetwebmedia.com/FWSubWebIndex/gldfshmalnut.htm and the linked files above... till you understand the inputs (about the same as you state above) along with the dried food issue for this fancy breed... and options for treatment. Bob Fenner> The Finks continued... 9/5/07 Dear Crew (and Neale), <Hello,> I wrote to you a few weeks ago about Molefink and Batfink, the 1.5" double-tails who were languishing in a 14 litre starter kit and I thought you'd be pleased to know that as of a week ago, they were upgraded to a whopping 40 gallon monster-tank (a Juwel Rio 180) courtesy of my other half who felt that one trip to the petshop for a big tank was better than fifty trips for medicine. <Indeed! I have the Rio 180 myself, and a very fine aquarium it is too. I did add a second filter though, and eventually a third, because I have a Panaque catfish in there who could poop for England in the Olympics.> I've put the foam from the little starter kit filter into the big filter to hurry up the cycling and in the past week they've shown dramatic improvements; we seem to be winning the war on diseases. <Big tanks = healthier fish = easier fishkeeping. No-one believes us when we say this, but buy a tank twice the size you planned on, and you'll end up cutting the work and expense in half.> However, Molefink has done something weird to his mouth. To explain, on the upper lip, the inner part that telescopes out and picks up gravel etc. seems to have come out too far and the little upside-down V has caught the outer skin. As he's closed his mouth, it's pulled the outer skin up. <Yes, seen this before in goldfish. It's a slight dislocation of the jaw.> I've been watching for a couple of days hoping that he'll do a big yawn and that the outer skin will pop back over the V and sit back where it should, but so far no joy. <Sometimes it does, sometimes it doesn't. Either way, it isn't anything to worry about unduly.> He doesn't seem particularly upset about it but I was worried that if it stays like that, from all the eating and gravelling and just general breathing, the skin might get sore and become infected or even split, and I didn't want to try wrestling it back into place myself because he's so tiny and I'm a ham-fisted giant in comparison. <Agreed; manipulating fish is possible but needs to be done extremely carefully because their bones aren't nearly as strong as you would think (because, of course, water carries they weight, not their skeleton). In all honesty, while it *might* be possible for a fishkeeper to re-locate a dislocated jaw, I can't help but feel this is something best left to a vet.> Is there anything I could (or should) do? <No, not really. So long as he's feeding, just let him be.> Or should I see how it goes? <Yes.> Thank you very much again, and for your help before. It's immensely appreciated. Claire and The Finks <Good luck, and good to hear things are working out. Cheers, Neale> Goldfish Behaviour: Odd? Crowded, uncycled, reading 8/30/07 Hi, great website, I've learned loads in the last couple of hours! I've had as good a look as I can, but haven't been able to find an answer to my specific question. Apologies if I'm just too blind to see it! <Okay> I bought a 18x10x10 inch tank (I can't figure out what that is in gallons ... math is not my strong point) <... there are about 231 cubic inches per gallon...> last week, and put a goldfish and a comet in a few days ago. <Won't be enough room...> I'm gathering from your site that the tank is too small (although the pet retailer said the tank was adequate for three goldfish, which is irritating) and I will upgrade once the fish are bigger. They're about 4cms at the moment and it doesn't look cramped, but: <...> Yesterday I noticed that every time they bump into each other (which is often as they seem to loiter in the same areas all the time) they sort of rub against each other and chase each others tails, rather like puppies would if they had fins and scales ;). I'm new to fish keeping, and while it doesn't look serious I can't decide if it's playing, mating behaviour, or a minor form of fighting which will get worse as they grow bigger. I really don't want unhappy fish and I'm not sure whether I'm worrying over nothing or if my concerns are genuine. I'd much appreciate any advice you could give me! Ellie <... this system is not cycled... The fish are poisoning themselves... may be other issues... Read here: http://www.wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm and the linked files above. Bob Fenner> Hi, just a couple of questions about Goldfish,
please... Sys., beh. mostly 8/26/07 Hi! You really have a
great website! <<Hello, Kim. Tom here.>> I just have a
couple of questions. I have 2 black moors and a goldfish. <<Not
being 'picky' about this at all, Kim, but your Moors are
Goldfish, too. I understand the distinction you're making,
though.>> I just changed out the rocks in their tank (I read the
rocks could be bad for them) to sand & the moors have been lying on
the bottom some. <<Goldfish do have a habit of picking up rocks,
which can sometimes get stuck in their throats. From this standpoint,
yes, rocks can be problematic for Goldfish.>> They still come up
to eat immediately & don't look sick at all, so wondering if
they are just sleeping? <<Goldfish aren't noted for sleeping
on the bottom of their tanks. This behavior is usually associated more
with some type of stressful situation/condition going on.>> Or if
it is constipation- (they do look fat). They do eat like they are
ravenous though, since I changed from flakes to worms. I don't
really have the opportunity to watch my tank during the day, but I
can't think of a time I've seen them poop. <<A
high-quality Goldfish-blend of flakes shouldn't be causing
constipation, Kim. The worms -- depending on what type of worms
we're talking about -- might contribute to this, though. Greens in
their diets should alleviate the problem as will brine shrimp, for what
it's worth.>> I have two snails to help clean & the sand
is white so I would be able to see it if there was some there.
<<Well, you may have given us a clue here with the white sand.
First, a white, or very light, colored substrate is unnatural for
Goldfish (and a lot of other fish, as well). The light reflecting off
of the bottom is disorienting for them. By that I mean that your fish
tend to 'orient' themselves in the water by seeing
'light' above them and 'dark' below. When they see
light above AND below, they lose their sense of positioning and become
stressed, the same way you or I would if we had no sense of up from
down.>> It has only been a week since I changed to sand though -
maybe not enough time for build up. I tell you what - those snails
really scour that tank though! So, should I try the Epsom salt for
constipation (1T/5 gal) or would it hurt if there were no problems? Is
lying on the bottom at all normal or should they just be swimming
constantly? <<The Epsom salt can be effective as a saline
laxative, Kim, but I'd rather see you try a variation in diet
first. Moors as well as some of the other fancy-variety Goldfish have a
naturally 'plump' appearance, anyway. Without a fair amount of
experience with these fish, the difference between a fish that needs a
membership at the gym and one that's legitimately bloated from
constipation might be a tough call to make. I'd also like to see
you purchase some black sand and try to darken up the substrate.
Ideally, I'd really like to see you change this out completely to a
dark substrate but it might be worth the trouble to see if a mix of the
two is enough to alter your Moors' behaviors. Hanging out at the
bottom of the tank is not normal for these fish so there's
something here that needs to be fixed.>> FYI- I have been feeding
them dehydrated worms lately. I have had a lot of trouble with the
water changing colors/clouding (even when the label said it
wouldn't) with other foods & can't really afford the
expensive stuff online. I have been trying peas - which they ate -
& romaine - which they didn't think too much of.
<<Zucchini and spinach are a couple of other items you might try,
Kim. Vegetable matter, at any rate, is the best way to go.>>
Second question. My goldfish has been nudging the belly of one of the
black moors, I don't know if this is bullying or trying to get her
to spawn? <<More likely trying to get her to spawn rather than
bullying her. Might also account for some plumpness in her belly if
she's carrying eggs.>> We did have a slight change in water
temperature, but not for a long period of time to encourage spawning.
Not really trying to have babies, but that would be cute.......little
tiny goldfish (: Let me know if I should trade the goldfish or give it
to a friend and get another fancy one. <<One thing I don't
know, Kim, is how large a tank your fish are in. If the
'Goldfish' is a Comet or Common variety, you require a much
larger tank than you would for the smaller fancy varieties. Even with
the two Moors and a 'Fancy', you'd really need a 40-gallon
tank, or larger, to accommodate them long-term. Given ample room to
grow and thrive, the move to trade/donate your Goldfish for another
variety isn't something I would recommend one way or another. Kind
of like telling you how to decorate your home if you see what I
mean.>> Any help would be appreciated! <<Summing this all
up, Kim, I would, first, darken up the substrate substantially. Second,
keep experimenting with vegetables until you find some (the peas are
good) that they'll take to regularly and, finally, evaluate the
size of your tank to ensure that your fish have the appropriate amount
of space. In this last regard, if your tank is 'small', i.e.
less than 40 gallons, I'd move this upgrade higher up on the
'priority ladder' to avoid bigger problems.>> Thanks! Kim
<<You're welcome, Kim. Good luck to you. Tom>> Discoloured Shubunkin 8/16/07 I am currently extremely concerned about my Shubunkin. <OK...> Approximately two weeks ago he developed a red lump on his side that then developed a fluffy white head. Within an hour of the fluffy white head's emergence it was gone. The next morning I went down to the local aquatic specialist and asked what should be done, the man there said that it was probably a parasite and now that the head was gone I should leave it a week to heal unless he started to deteriorate in which case they would examine the fish for me. <Hmm. Not what I would have done. Any time there is a mysterious growth on a fish that could be either fungus (which is fluffy) or finrot (which is red), I treat at once. Both these diseases are easy to cure early on, but virtually untreatable when advanced. Since medications are cheap and safe when used properly, there's nothing to be lost by "jumping the gun".> However we got onto the subject of the tank that I was keeping my fish in. I had bought a 25litre tank at another local pet store and had been assured that it would safely hold 4 goldfish, and was more than spacious enough for my goldfish and shubunkin. I was informed that this tank was far too small for my fish and ended up buying a 65litre tank. I fully intended to cycle the tank before I used it but was told that as long as I added all the water from the previous tank that there should not be a problem, in-fact the extra water would help the parasite problem which it did and now the red lump has disappeared. But that I should wait a few days before adding plants. <Even 65 litres is borderline for 2 goldfish. Regular goldfish are really pond animals, and need something around 100 litres each; fancy goldfish are certainly aquarium fish, but need only marginally less space. The problem is goldfish are [a] big and [b] messy. In a small tank they can't swim about much and their constant sifting of the substrate overwhelms the filter and makes the water murky. You might be fine for a couple of years with what you have, but once the fish reach around 15 cm long (and they will) you'll see very clearly where I'm coming from here. Retailers are UTTERLY useless on goldfish. Many retailers would happily sell goldfish in bowls without filters and a little pots of ants' eggs for food. So read, learn, and make your own mind up.> When I went to add the plants I was told to remove the bubbler from the filter, however the fish started surfacing a lot more than usual (especially the shubunkin) so I decided that I would rather lose the plants than the fish and decided to put it back in which seems to have alleviated the problem. <When the fish gulp for air, it means water quality has dropped. Do you have a filter?> However the shubunkin has now developed a red discoloration on his main body and along the base of his dorsal fin, which I am assuming is down to ammonia poisoning because the tank was not cycled properly. <Correct. Treat for finrot and fungus immediately.> Normally I would perform a large emergency water change. However we have had extensive flooding in our county which has meant that all the water in the treatment plants has been contaminated and the water has been cut off for potentially 7-14 days so it is hard enough to get hold of 2 litres of water let alone 20 and I don't think that the emergency services or armed forces that are currently assisting us would provided me with that kind of amount on the basis that I think my fish might be sick. So I was wondering if there was any substance that could be added to the water already in the tank that might help temporarily neutralise the ammonia and the damage that it is doing to my fish until I get the opportunity to perform said water change? <Non-iodised cooking salt can be used to detoxify ammonia over the short term, at a dosage of around 3-5 grammes per litre. Increase the salinity in the aquarium gradually, perhaps by adding the salt in batches across 4 days. A better solution is to buy some zeolite ("ammonia remover") and fill a bubble-up box filter or similar with the stuff. This removes ammonia directly. You will need to replace it every couple of weeks, but it's cheap, and as a stop-gap, very effective.> Any help would be appreciated Tamara x x <Hope this helps, Neale> Goldfish hanging on surface 8/12/07 I have noticed
from quite few months that one of my goldfish hangs on the surface. It
also never goes down at night and sleeps on the surface only. <Mmm,
not good> It's other activities are fine. It eats properly swims
properly etc. But it just floats on the top. Now from last one month my
another fish is doing the same thing. What is the reason. Is there any
problem. Because rest all other things they do perfectly fine. Pls give
remedies <Please read here:

Fenner> Goldfish... beh. 8/5/07 Hi, I bought two goldfish a few days ago. One of them has just begun to float upside down. Its gills and eyes still move though. Once in a while it will go swim around but end up floating again. When we first got it were thought it was pregnant because it is so huge. Now I am not sure if it is dying or pregnant. Any help would be appreciated. Thank You! <Greetings. I can't really offer any advice here because you don't give any information. How big is the tank? What sort of filter do you use? How long has the tank been established? What are the nitrite and ammonia levels? What is the pH and hardness of the water? What do you feed your goldfish? How often do you do water changes? How much water do you change? Do you use dechlorinator with each water change? All these are factors that need to be considered. Usually the problem is people stick their new fish into an immature aquarium and the poor little creatures end up being poisoned to death by the appalling water quality in the tank (or, God forbid, bowl). Make sure you read the articles here at WWM on goldfish. Goldfish *aren't* easy to keep, and far too many people forget they are animals and treat them with no more compassion than a pair of shoes. Cheers, Neale> Goldfish gulping air after eating 5/25/07 Hello! <Hi there> Hopefully you can shed some insight on this for me. 75g tank, 0 ammonia, 0 nitrite, 20 nitrate, <Borderline high... I would not let this get any higher...> 8.0 pH, 300+kH, 300+gH, 75* temp. My goldfish gulp air after eating for 1-2 hours. They ONLY do it after eating. <Mmmm...> All of their food is pre-soaked and they do not eat from the surface as it sinks as soon as it's put into the water. They do not gulp air during feeding but rather after a feeding. I have tried more food, less food, different foods, killing the air stones during and after feeding (thought they might have been confusing bubbles for food) and they still do it. They also yawn throughout the day. When gulping, they allow the air to bubble out thru their gills while at the surface. <Sounds/reads like they're either getting too fat, too much food, and/or there is insufficient gaseous diffusion> This is not being caused by gill parasites (have been tx'ed with formalin/malachite green and also Praziquantel). This is not low 02 sat as I have tons of surface agitation. This is a problem specific to my 75g tank. Two recent additions were quarantined for a few weeks in a 20g QT tank. Neither fish yawned or gulped after a feeding. They were being fed the same foods as the fish in my 75g. Within a day of being in the 75g they BOTH started yawning and gulping after meals. <Interesting> The only difference between the 20g QT and 75g display is the gravel and the 75g has a bunch of hornwort and java moss in it (which the little piggies graze on constantly). I also have a diatom problem in my 75g that I can't get rid of (have tried Ramshorn snails, silicate and phosphate mitigation via Phos-Sorb). <I'd try growing some purposeful aquatic plant/s... to use the same nutrient, light, compete chemically... My fave (the one I use with my goldfishes): Hornwort, aka Coontail, Ceratophyllum...> I have never, ever had a diatom problem in any of my three tanks for the 8 years I've been in this hobby. I am convinced it is the gravel leaching silicates (hence the diatoms) and something else (hence the yawning and gulping) into the water that is irritating the fish's gills. <Again, very interesting> This gravel was bought at Wal-Mart (Aqua-Culture brand IIRC) and was packaged and labeled for aquarium use. I am just about ready to go bare-bottom in my 75g to see if it stops the gulping. I have been removing the gravel slowly so as not to shock the biofiltration in the tank. I now have a single layer of gravel and can safely remove what remains in one fell swoop. Before I rule out the gravel by removing it............can you think of anything I have missed? Mike <Well... I would first try switching the food... my choice here is the Spectrum brand of pellets... And the plant... either the species mentioned above, or Egeria/Elodea/Anacharis... Bob Fenner> Shubunkin/comet very lethargic please help 5/20/07 good morning, <Yawnnnn!> I have looked around the www and couldn't find a definite answer and I need help. Thankfully, I found your site, but couldn't find this issue. We have a 30 gallon tank with a small catfish and a shubunkin/comet. I am not sure what he is. But I know something is wrong. He likes to clean the gravel in the tank and spit it out. I am worried he has a piece of gravel stuck and he is very lethargic. He props himself up on one of my tank decorations and just sits on the bottom. When I fed him yesterday he seemed disinterested at first, swam to the top, and returned to the bottom by drifting down. I don't know if he is lonely or if he has in fact swallowed a piece of gravel. I have been wondering if gravel was a problem for these, but the fish store had him in a gravel lined tank. I keep the tank extremely clean and have never had this problem with him since we got him 5 years ago. If it is gravel stuck, what do I do? <Perhaps nothing... wait and see if it is gravel, if the fish does/can spit it back out... Or, be a bit more active, catch the fish, hold it in place, probe gently, try to extricate the gravel (with forceps, tweezers, a wooden toothpick...)> I know the first thing is to get it out, but how? Then get rid of the gravel and go for marbles? <Mmm, no... The real/root problem here actually may not be gravel... but the environment... likely metabolite accumulation... Do you have water quality test kits? Even just measuring, relating ammonia, nitrite and nitrate concentration here will be helpful...> I don't want him to suffer and the catfish seems fine. So it is definitely something with him. Please help... Many Thanks, Cathy <Please help yourself by reading here: http://www.wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm and the linked files above. Bob Fenner> Goldfish behavior problem 5/11/07 Hello Crew! I had just written to you about the black moor goldfish, and asked some general questions, however I have a slight problem that has just occurred within the last two days. I own two black moors, in a 20 gallon tank, <Will need more room than this> water is filtered, all chemicals check out, etc. The fish are both approximately 1.25-1.5 inches long (nose to end of tail), and have only lived in this aquarium for less than one week. <Is this system cycled?> They have been taken from the same aquarium at the pet store. I set up the tank, let it settle, etc. and introduced only one black moor the first day (accompanying fantail died upon arrival, and was never introduced), and introduced the second black moor on day two (after return of fantail). The first, Zircon, is bullying the second, Onyx. He nips at her anal region, and it almost seems like it could potentially be a mating thing? <Mmm, no> Because these fish seem relatively young, I didn't think this was the case - what else could it be? <Environmentally driven agonistic behavior...> Just a mean fish? Not really knowing the gender of these fish, is there a way to tell? <Not at this size, no> I have not located any tubercules (sp?), most likely because of age. <Correct> Is there anything that I can do to stop this behavior? <Check your water quality... for ammonia, nitrite, nitrate mostly> Both fish seem completely healthy, are both eating well (love peas!), and Onyx does not show any signs of bitten off fins. Please let me know if there is a solution (adding more plants?), <Might help> or if it's just a mean fish. Thanks! Megan P.S. Water temperature ranges from high 70s to low 80s. <A bit high on the upper side... Do you have a thermostatic heater here?

Just for a reassurance, the tank has been cycled (or is at the very very end), <Any ammonia, nitrite presence will damage and have damaged the fishes health... change their behavior> and all water quality issues are currently out of the picture! :) However, is it normal for a "black" moor to actually be on the verge of bronze/black in terms of coloration? Will he ever be black again? Thanks again! Megan <Can be normal, but also can be stress-induced... and can recover blackness with time, good care. Bob Fenner>
Goldfish with frayed, blackened fins 4/30/07 Hello fish experts. I have two goldfish in a 6 gallon <Too small a volume...> tank which have developed fraying fins (fin rot?), <Environmental...> but also these frayed edges have begun turning black. I have only found one question on this, but it was after the fish was dead! My fish seem to be behaving normally. I changed about 30 percent of the water and tested it. Everything was normal, except the water was quite hard and alkaline. I also put in a product called fungus clear. That was three days ago and I have seen no improvement. How long should this take to clear up and is there something else I should do?

When I came home today (lights were out) and they were thrashing through the tank after each other. Mostly after the red cap and then breaking into pairs chasing each other. Is it mating season? <<It's an over-stocked tank.>> My red cap seems exhausted, I caught it in my net and have it floating to give it a break, although the comets are still chasing each other, they keep coming up to the net and sniffing around her tail and mid section. Should I get a divider for the tank as I have no room for another tank (or for that matter more fish). The kids won the comets at a carnival 2 yrs ago. HELP! <<I'm sorry, but your tank is just too cramped. Perhaps offer the fish to a friend with a pond, where your fish will grow to their normal 1-foot plus in length. Lisa Brown.>> A missing fish, goldfish gone 4/14/07 Hi, <David... Am sure you're aware of your famous namesake... in our, other interests... the first president of Stanford...> I have four little goldfish in a tank that I am starting to realize is too small. (10 gal, for 4 2" fish.) <Ah yes... too crowded> It's your typical tank with a top-light, cascade type tetra filter (sucks the water up, puts it through carbon filter, cascades it back in). One of my fish, who has seemed perfectly healthy, has simply disappeared. I have searched the area all around, and don't find a corpse anywhere near the tank. I have checked the water levels and they are right in line. How can he have simply disappeared?? If he died while I was at work would the others have eaten him? <Mmm, not that quickly... likely did "jump out"...> There are several inches of clearance to the top of the tank, <Mmm... makes the leaving more difficult...> plus a lid, and I can't imagine him jumping it. <Do you have an "algae eater" here?> Please let me know that I am not going insane! thanks, -David <Perhaps a thief? Bob Fenner> Separating aggressive goldfish 2/14/07 Hi There, <Sossy> Thanks for all the great info... I'm always on the site learning new things! <Me too!> I have a 25 gallon tank that only had one black moor in it. It's now become large enough that I know it's a male. I was told that goldfish love companionship <Mmm, are actually sort of "autistic"... don't particularly need, yearn for company> so I went and got another (albeit smaller) orange fantail. I didn't know the sex of the fantail until the second day it was in my tank when it suddenly developed tubercles on it's gills and fins, so now I know it's also a male (I was hoping for a female). Anyhow, the moor was chasing it non-stop, and to the point that it was ignoring it's own pellets when it was feeding time. It just swam alongside the fantail trying to nip at it's pectoral fin while the fantail was going on about it's business. <Yikes... a good idea to separate> I immediately put a clear separator in the tank to stop the aggressive behaviour. <Good> My question is, do goldfish get used to each other or will I never be able to get rid of the separator? Is there anything else I can do? <Sometimes do learn to "get along"... only trial can/will tell... and time going by. What you have done... the clear separator... is best to allow them to see and smell each other... Perhaps try its removal when you can be around to observe... a week or so from now> Thanks for any/all your help. Sossy. <Bob Fenner> Re: Hello again, goldfish beh. 2/27/07 Hi there WWM Crew, <Hello> Thanks for your recent advice about separating my older moor and my new fantail. They are getting along well without the clear divider. <Ah, good> I do have another problem now, however. Recently (before I introduced the fantail) my moor, who is about 1 year old and gorgeous, somehow got one of his eyes deflated. <Happens... most often from a physical injury> I wasn't sure what caused this, but I followed the advice you had given someone else in an article I read on your site by putting dissolved salt in the aquarium. Nothing happened. His behaviour did not change at all - he was still active, appetite was fine, his colour clear and fins were perky, so I left it alone. I guess I shouldn't have because now he's totally lethargic, breathing rapidly, AND his eye is still deflated. His fins are clasped so I know something is really wrong. <Mmm, the most likely trouble is the bio-filter bacteria were disturbed by the salt...> I have a 25 gallon tank which I religiously clean once every 2 weeks (20% water changes as prescribed). I medicate it with Nutrafin cycle and tap water cleanser. I have real plants which I feed iron to each time I clean the water. My gravel is very clean, the water is clear, and I always test my water weekly... all is well. So what can the problem be? <You test it for what? Ammonia? Nitrite?> In terms of diet, they get Hikari Lionhead sinking pellets (about 5-7 each twice daily) and there are many plants and a little green algae for them to nibble on. I hope the information I have here is enough for you to help me figure it all out!

The gold Fantail (Minnie) is suddenly much larger in the back side than Mickey. <Minnie got back> It's like she ate two balloons and shoved them behind her gills. Now I know fish don't get pregnant but I suspect she may be full of eggs <Mmm, no... not at this size> as she is otherwise happy and healthy and just as sprightly as ever despite her bulbous condition, always begging for food as soon as you look at her. And Mickey is chasing her everywhere and has been for about a week. <Not atypical goldfish behavior... and not a worry unless "excessive"...> He is also in perfect health. I have bought some very leafy plants in the case that she needs somewhere to lay her eggs (forgive me I am a goldfish moron and am going purely on every fact (I use the term loosely) I have ever heard about goldfish). <No worries> If she is pregnant (so to speak) will I notice the eggs when she lays them, how long before that might happen, do I need to banish Mickey to avoid him snacking on his children? <Again... likely the development is simply "expression" of genetic potential... the fish doing what it's going to do... Do take a read on WWM re Goldfish Systems... and take care re maintenance of this small volume... too easy to get into trouble.> Thank you!!! Fish lover and fish idiot. Chanelle. <You're in good company here. Bob Fenner> Shock!!!!!!!!!!!!!!!??????????? Goldfish beh. I recently changed my two goldfishes tank, and both of my fish just laid on the bottom of the tank, is this shock due to water temperature? <Mmm, maybe... but most any type of stress, difference in water conditions might lead to this behavior> Is it possible for them to survive? Is there anything that I could to help them out? Please get back to me ASAP... Thanks. Mike <Please read here: http://wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm and the linked files above. Bob Fenner> Fish help! Goldfish comp., beh. 1/30/07 Hi WetWebMedia crew member, <Jennifer> First of all, thank you for your information on pet fishes. I was learning <Was? No longer?> a lot, and it helped me to take care of my two Black Moors. But now I have some issues I'm not able to find much answers on. The two Black Moors' names are Chocolate and Pudding (together, they're chocolate pudding). <Clever> The first problem, Chocolate is a much thinner goldfish with very long full fins. It seems like no matter what he eats, all the nutrition goes straight to his fins. <Heee!> I've had the two Black Moors for about a year now, but Chocolate has not grown a bit unless you're measuring the fins (2.5 inches in length, but its 30% body, 70% fin, and 1.5cm in width). On the other hand Pudding has grown nearly 1.5 times as big (now he is about 3 inches in length, and 1 inch in width). <Perhaps in retrospect these Goldfish might have been named Laurel and Hardy...> Chocolate has such a small body, with long fins. I mean the volume of both of his eyes is as big as the body. I'm just wondering is that normal? Is there anything I can do to enhance Chocolate's growth? <Is likely normal... All goldfish "breeds" are resultant from a cross... are the same species... some with longer finnage, some of the fins split/doubled, some with bulbous eyes, some with more roundish bodies... differing color...> The second problem, during December, I went on a family trip. I left Chocolate and Pudding with my boyfriend. Now that I have gotten them back, Pudding seems really violent towards Chocolate. <Not good... happens at times when "not so fancy" varieties are mixed with fancier (rounder) ones> At first there was just one split fin, I just thought it was an accident. But just last night I discovered that Chocolate has many split fins (total of 5). Then just today I saw Pudding bumping into Chocolate. It wasn't like swim into each other bump. it was more of tackling. Chocolate panicked so badly, he spent the rest of the day wedged behind the filter (where pudding can't reach him). Chocolate only comes out to eat, then he hurries back behind the filter afterwards. I don't know how long that's been happening, but it's making me nervous. I was going to separate them, but I don't have a spare tank. Is there an explanation for this? Sincerely, Jennifer <Mmm, I do hope this is only a temporary, likely breeding behavior-related incident... Otherwise and just the same, I would separate these two for a week or two... a bit of rigid screen (perhaps a piece of louver (see Home Depot, Lowe's) broken into a partition in the tank> PS: Thank you for helping me! <Welcome my friend. Bob Fenner> Bubble-eye behavior 1/29/07 Hello, This is an odd question for which I can't seem to find the answer. I have had 2 goldfish for a year now (1 Ryukin & 1 bubble-eye) in a 10 gallon tank (which after much research I now realize is much too small). <Yes, good> The sacs on my bubble eye goldfish are much larger than any other bubble-eye I've ever seen. The width of the sacs is longer than the length of his body. When at rest "Mr. Bubbs" largely remains at 45 - 80 degree angle at the bottom of the tank. He is able to swim normally, but has been spending a larger amount of time "resting". He appears healthy in other respects. <Is a pretty typical situation> I am wondering if this resting behavior is due to a swim-bladder problem or if it is due to the weight of his sacs. Thank you very much! Heather in NY <I think your guess at the eye sacs... along with this "breed"... all goldfish are the same species (actually di-hybrid cross)... I don't think there is anything to be concerned about here... other than regular/good maintenance and getting a larger system. Bob Fenner> Goldfish bullying ! Time to thin out the pack 1/29/07 Hi Bob, <No...Adam_J with you tonight.> We bought a Bi Orb tank a month ago along with one single goldfish as instructed. <Much too "dirty" a fish (produces a lot of waste) for such a tank design.> Yesterday, a month later we bought two more ( a fan tail and a Ryukin ) and introduced them to their cell mate. <Hehe, interesting...but appropriate analogy.> After a very short time , the Ryukin who is slightly bigger, started chasing the other two and nibbling their tails and bashing them against the tank. Please help us sort out this thug ! We do not tolerate bullying in this household !! Should we return it to the shop - guilty GBH (Gold fish Bodily Harm !) <Yes remove two/three....in fact a single Betta or a duo/trio of white cloud minnows would be better off than goldfish in this tank.> Sally W <**AJ> Goldfish fins turning black fairly quickly 1/21/07 Hey there,
I love the site and always check it when I have any questions but I
have an orange Oranda goldfish about 2 inches long not counting the
tail. I was hoping you could give me some advice on what I should do
(if anything) with a color change that the fish is going through.
<Mmm, these changes do "just happen"... not likely
anything you actually "can do"... other than provide good,
consistent environment, nutrition> The top and bottom tips of one
side of the tail and also the tip of the caudal fin on the same side
are turning black fairly quickly. The fish has been doing great for the
last 3 weeks since we successfully treated the tank for an outbreak of
ich with Nox-ich at that time. <Mmm... well, the Malachite Green may
actually have triggered something here... still, largely a genetic
pre-disposition> The ich cleared up right away, and the goldfish and
it's tank mates - a big snail, <Surprising this wasn't
killed by the med.> 4 small panda catfish and 1 small Pleco - are
all doing great. Fins are perky and everybody is excited to eat. We had
just got a 10 gallon quarantine tank up and running and were hoping to
introduce 3 new goldfish after a week or two but now we are worried
that there may be something wrong in the main tank. <Not that this
color change would portend... but the fact that the snail survived the
Malachite exposure indicates to me that the ich is likely still
present, sub-clinical... that it could easily be expressed> The
stats are as follows: 55 Gallon tank with 2 live plants in it and an
Aqua Clear 70 filter Temperature appx. 73 degrees pH is 7.8 Ammonia is
about 0.1 - 0.2 Nitrite is < 0.1 The General Hardness is 120 mg/L
The Carbonate Hardness is 130 mg/L Is everything here OK or could there
be a problem? Thanks so much for you time, as we are eager to keep our
fish healthy. They were originally a compromise when we decided we
didn't have time or space for a dog. It's amazing how much you
get attached to the little guys. Cheers, Matt <Ah, yes... I would
proceed as you state, with the careful few weeks quarantine of the new
goldfish... testing for ammonia, moving/changing water out in the new
10 from the extant 55. Bob Fenner> Goldfish in danger???? Beh. 1/19/07 Hi, just a quick question regarding my cold fresh water 3ft tank. I have a 15cm comet and 3 small comets. I have been told that the large one is a female. My problem is that the 3 smaller fish seem to attacking? the larger one. <Mmm... likely a sexual drive...> I have noticed that the large fish has a hole just under its tail fin area and that there seems to be tiny white particles coming from it.. <Likely unrelated... but possibly instigated by damage, and/or stress> this also seems to be where the smaller fish are attacking. Just wondering if the large fish is been attacked or could it be that it is spawning or something else?????? <Spawning... but possibly furunculosis, Anchorworm... Many possibilities... please use the search tool on WWM to search the terms, Goldfish spawning, breeding, disease, furunculosis, Anchorworm... altogether. Bob Fenner> Thanks you Goldfish beh., sys. 1/14/07 <<Hi, Susan. Tom with you.>> I have a fancy goldfish in a 30 gallon tank. <<Good, good, good! (Can you tell I'm pleased with the size of your tank?) :) >> He is 2 years old and 8 inches long. I installed a magnum 350 canister filter yesterday. Since than he is not eating and will not stop swimming around (he especially likes to play swimming nose first in the out current) Is this too strong a filter for a 30 gallon tank? Why is he not eating? <<Well, you've got 11+ water changes per hour going, Susan, which is actually optimal for Goldfish. In a community tank, I'd say this is a bit much but not in your case. As for his eating, or lack thereof, is his food getting tossed about vigorously? He's going through a re-acclimation, if you will, and might not be accustomed to working 'hard' at eating. Could be that he's simply uninterested right now what with the new developments in his home. Once he's gotten used to the change in his environment, his appetite will rebound. We use the term 'stress' typically in a negative connotation but this occurs in varying degrees any time a fish is subjected to something other than what he/she is used to even when it's for the better. When he figures out that the increased water movement is 'normal', he'll be back to his old self. No worries.>> Pls. help...Susan <<Good job on the tank and filter, Susan. Tom>> Listless goldfish... No useful info. 1/11/07 Hello WWM Crew! I've been searching online for about 3 days now, trying to figure out what's wrong with my fish. I've tried to take them to the pet store where I know there's a fish expert, but they don't act the same way when I transport them, so he didn't see anything wrong. So now I'm finally asking for your help. <Okay!> I have three goldfish (two fantails and a comet). I've had the comet for about 3 years, and I just bought the two fantails. I used to have 3 comets, but the other two died because if Ick, Flukes, and finally fungus that were brought in by a diseased fish, which was a case of really bad judgment on my part. <Happens> In any case, since the other fish died, he's been really sad-looking, not swimming alot, <Not a word> and kind of becoming the fish version of a couch potato. I decided to buy him new tankmates in case it was loneliness. I made sure that the new fish were healthy by keeping them in a separate tank for about a week, and I treated both tanks with an all-purpose medicine to make sure any outer parasites/fungus/bacteria were killed off. <Good plan... but I'd make this quarantine period a good two weeks> When I introduced the new fish to the comet's tank, they were really lively for about a day, perked up my comet, and I assumed that everything was fine. The next day, they were all just sitting at the bottom of the tank. There's no signs of outward disease, I've been doing water changes for about 4 days now, and they seem to be fine at feeding time as well, which told me it wasn't a swimbladder problem. I've cut the amount I feed them in case it's overfeeding, but that hasn't worked yet. They also seem to sometimes "shimmy", but I'm not quite sure what that's supposed to look like. For the most part they just stay still at the bottom of the tank, barely breathing, but they don't look like they're out of air at all. I'm really worried about these guys, especially the comet. I've had him for so long, and my previous mistakes cost me his first tankmates. I was so upset when they died, but at least I still had one. Please help soon. Thank you! ~~Kit <Kit... what re water quality? Testing? The size, filtration of this tank? The types of food offered...? Well, you may have nothing other than cumulative stress going on here... but could have a pathogen (not apparent) acting as well... Or just some aspect of environment out of kilter. Please read here: http://wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm and the linked files above. Bob Fenner> I'm a little curious. Fading goldfish color, comp. with Mollies 12/25/06 I have a beautiful fish tank filled with aquatic plants and gravel plus along with it is my wonderful fan tail, common goldfish, black moor, Oranda, and finally Ryukins. They all get along fine!! But my question is that one of my Oranda is very healthy but its red cap is starting to fade and turn to a yellowish color and I don't know what to do to help it!!!! <Does happen to some goldfish... genetic, developmental... Good water quality, nutrition, are the roads to maintaining, retrieving color... if possible at all> and my second question is that I really love balloon mollies and I did a research on them and found out that they are really peaceful fish just like the goldfish so I was wondering if pot belly mollies and other mollies can be in the same tank as the goldfish???? <Mmm, can... have similar likes in the way of water quality, agreeable temperaments... Though I still like the "looks" of all-goldfish set-ups. Bob Fenner> Re: On the safe side. Goldfish color change 12/26/06 Hey thanks for answering my questions you really helped me out a lot!!! <Welcome my friend> To be on the safe side, I just wanted to ask "Even though the red cap of the Oranda is fading, but the fish is still healthy...will he remain healthy???? <Yes. Likely no other change to be expected here. Some individual goldfishes do just sometimes undergo such color changes... Might well convert back to something more red here in time. Bob Fenner> Goldfish behavior question 11/18/06 Hi! I have a quick question about a funny behavior my Oranda is displaying. I have a 20 gallon tank with two Orandas and a bunch of live plants. I noticed the other day that one of my Orandas will swim right up to the filter output and swim against the current! <Ah, yes... quite common> The tank is totally cycled and the fish isn't displaying any signs of problems. He just swims around all day eating the plants. <What a life, eh?> I did notice that there is reddish/purple algae that grows on the part of the filter where the water comes out. Is the Oranda trying to eat the algae? <Mmm, doubtful... this algae is likely unpalatable.> If so, is it bad for them? <I would keep it wiped off, during water change days...> I ask this because I have a second tank which is a 30 gallon that also holds two Orandas and has been stable for over a year with no new fish added. One of the other Orandas I have had for 8 months displayed that same behavior and just recently he died. He didn't show any problems, just started staying at the bottom more. The tank tested 0 ammonia, 20 nitrates, 0 nitrites. Then one night he was dead. The other fish looks great and hasn't changed his behavior. I have no idea what happened. <Mmm... might well be "anomalous"... unrelated to the algae, or behavior> Thank you very much for any help you can provide! -Shannon <As much as current media seems to discount play behavior, creativity in all but humans, it is my sensation that many fishes do engage in these "non-fixed point" undirected actions... because... they're fun... and possibly such adventitious behavior has some discernible individual/species "preservation" value. Bob Fenner> Odd fantails... beh. - 11/05/06 Hello from England! <<Hello from the U.S.! Tom with you today, Monica.>> I recently bought two fantails and am fascinated by them but I am not sure about their behaviour. <<Okay'¦>> I was quite worried when one of them started chasing the other round and butting into it and pushing it around also by sticking it's snout up the other one's bottom and pushing it around. <<Aggressive behavior such as this is a good indication of stress.>> Well, I wasn't sure what to do but now the aggressive one has taken to hiding in a cramped spot behind the vase and the pane of glass whilst the mild mannered one swims round freely without any bother. It's very odd because the aggressive one (Frida) will stay in the same position for ages and ages and remain hidden and cramped with it's tail against the vase and it's snout against the glass pane. <<Another sign of stress, to be sure.>> However, when feeding time comes and I approach the tank they become far more lively and swim around the main area of the tank. The mild mannered one (Diego) also has times when he chooses the corner of the tank, to snuggle in there and just sit on the bottom. No idea why they do this when they have space to swim around in. Any help please? <<Monica, you don't say whether, or not, your fish tank has cycled or what your water parameters are. You also don't mention the size of the tank that they're in. Fish certainly require some time to acclimate to new surroundings following a move but I'd be suspicious of their water conditions. Frequently, though not always, poor water conditions will lead Goldfish to spend a lot of time gasping at the surface of the tank. This doesn't seem to be your case but I wouldn't rule out the possibility. Poor conditions can/will lead to abnormally aggressive or reclusive behavior such as your pets are displaying, as well. It could also be that the water temperature is unsuited to Goldfish, specifically if it's too warm. Living in England as you do, this would seem unlikely but something to look into nonetheless. Goldfish will do fine up to about 75 degrees F. (24 C.) but 68-72 F. (20-22 C.) is probably a better target temperature. For now, I would concentrate on water conditions, however, particularly ammonia, nitrite, nitrate and pH levels. If you don't have a water test kit, I'd recommend one but, at the least, your fish shop should be able to test a sample for you. Returning to my original point, if you haven't cycled your tank, there's work ahead. Goldfish are messy creatures and the parameters I've mentioned can go through the roof in no time.>> Many thanks Monica <<Happy to help, Monica. Cheers, Tom>> Goldfish behaviour question 10/4/06 Hello, <Evening> I've been trying to find out information on a habit my Oranda, Angel, has on spitting (?) water but all I can find are topics on spitting food. (which my Oranda would never do, he's a pig lol) <Heeee!> He's been doing it a lot this week also. He'll swim around for a while, go up to the top (usually the corner) and stick the top part of his head out and I'm not sure what he does next because its fast, but he either slaps the top part of his mouth down or closes his mouth real fast and makes a slapping, almost popping sound with the water. Its loud enough to hear on the other side of the room. <Interesting...> This also makes bubbles about as big as his eyes and when he makes enough he'll go down and bite them all. I can't figure out if its just his way of playing or what but I know using the "ignorance is bliss" mentality usually gets fish killed. Whenever he does this my Ryukin, Spike, gets excited and usually joins in. If you have already answered this question then I'm truly sorry. I looked through the FAQ but there are just so many that I cant look through them all at once and I kept forgetting where I was when I would come back. If you don't know what the mouth thing is about I could upload a video on youtube or something so you could check it out. Thank you, Hannah <Would be hilarious. I do think your goldfish/es are trying to get your attention as well engaging in a bit of play behavior. Bob Fenner> Help! Roguish goldfish beh. 9/30/06 Hello, I have a really weird question for you. My mother has a tank full of goldfish, now the problem is that some have started to eat the tails off 4 of the pot bellied gold fish. <Mmm, some types, individuals of goldfish are not compatible with "fancies".... especially if crowded> She feeds them 3 times a day, and they still seem to do it. She has now moved the pot bellied ones out of the tank and put them in a tank of there own. <Good> Now why would they be doing this, to only these certain fish????? <Yes, correct> We are fish people and are now very very stumped. The one fish will not make it to much longer. Please e-mail me back with your answer, whether or not this question can be answered. Thank you Courtney <There are such "rogue" goldfish that learn to pick on, eat others... they need to be isolated, or destroyed. Bob Fenner> My gold fish is at the bottom of my tank but is still alive. What could be the problem and how can I help it? 9/29/06 <? Please read here: http://www.wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm and the linked files above. RMF> Black Moor and lionhead - URGENT 9/26/06 I am so confused by
differing information not just from different aquarium shops but also
by different staff from the main shop I use. <Need to investigate,
educate yourself... make up your own mind...> My tank is 30litres
and at the moment I have one small black moor and a slightly larger
lionhead. <This tank volume is too small...> The tank was set up
on 1st August, the black moor put in a few days later when the water
levels were ok. <Not useful... discrete data please, not subjective
evaluations> 3 weeks later i put the lionhead in. At first the black
moor seemed to bully the lionhead, looking like it was chewing its tail
but not causing damage and I was worried, but it seemed to settle down.
<...> For the past 3/4 weeks I have been having ammonia problems,
<......> (possibly caused by having an additional fish or from
having to feed peas because the lionhead has swim bladder problems)
<.........> necessitating a daily water change of about 10% with
added 'Tap-safe' and also additional bacterial product to boost
production. The levels have now reduced and I thought I was on the
better side and my fish were safe. However yesterday I noticed that the
lionheads tail looked chewed, the aquarium asked me to take the black
moor in to check for bacteria under the microscope, it was clear, so it
seems that the black moor is actually eating the lionheads tail now and
caused quite a bit of damage. I have now started using anti-bacterial
product to help with the healing, but i just don't know what to do
about taking the black moor back to the shop. <Return one or
both> Last time it settled down and I don't want to have to
return a living thing with a name when its something that might rectify
itself. <Highly unlikely in this setting> I bought these fish as
I thought it might give me something else to occupy my time whilst
going thru a break-up, and a couple of weeks ago when i thought i may
lose them because of the high levels of ammonia i was in tears, so I
really don't want to have to take one back. But I do wish now that
id never started with the fish, they are certainly a lot more hassle
than i ever envisaged. Please try and reply quickly as I have to make a
decision tomorrow if I have to remove the black moor. I have no way of
having another tank, ive already spent a lot of money and i don't
have the space. Thanks Lisa (Manchester, UK) <Return one/both...
long walks... new hobbies, contact old friends... Bob Fenner> Lethargic goldfish - 09/14/06 Hi there! <<Hello, and my apologies that you've waited so long for an answer. Tom>> I've just recently acquired two goldfishes from a carnival and not bearing to dispose of them, I decided to give them a home. I housed them in a 2ft x 1ft tank filled with 7 inches of water, which I hope is sufficient for them for now? (They're around 2 inches long each, including the tail.) I placed some pebbles and water plants in the tank but did not include lighting as the tank is placed in a well lit place, away from direct sunlight. I also used box filters in the aquarium setup. <<A quick mental calculation places your new pets in a tank of about 7-8 gallons of water. Honestly? Not enough...>> Initially both fishes looked fine and they both ate healthily and swam actively, exploring the entire tank. After 3 weeks though, one of the fish started behaving lethargically and would rest for long periods on the bottom of the tank without moving. Occasionally it would seem to float with the head pointed downwards as though it has difficulty straightening itself, yet it has no problems swimming around the tank during feeding time. It is still eating though it does seem to suffer from reduced appetite. I tried checking for dropsy, ick, or anything other signs of disease on the fish but the fins and scales look fine. <<Likely your fish is having problems with its swim bladder. Goldfish are notorious "gulpers" when it comes to feeding and your fish might simply have ingested too much air. This is a common cause of this. Without more information, I wouldn't suggest that this condition is based on an internal disorder.>> I feed them with flake food twice daily and supplement it with boiled peas once a week. Water changes are done twice weekly with 20% of the water changed each time as it's a new tank and I'm concerned about ammonia levels. <<Good. In this small of a water volume, ammonia levels are certainly going to be an issue. Excellent that you're keeping abreast of the water changes, though. Very wise in this case.>> I can't seem to get my hands on a water test kit locally and I'm not sure if the water from the tap contains any other chemicals harmful to the fish. I do leave the fresh water from the tap out overnight before any water changes. <<Again, a good practice. Chlorine dissipates quickly and will be in the safe range if left overnight. Chloramine (chlorine + ammonia) is utilized in some areas since it doesn't dissipate like chlorine, alone, does. There are products that treat for both at the same time, just for what it's worth.>> A point of concern is that the water starts to have a tinge of green after 3 weeks even though I don't see algae growing in the tank. <<A "bloom". Nothing, right now, to be concerned about.>> Please advise on the condition of the fish as I'm not sure if it's a normal condition, or if it's suffering from some disease that I can't see. Is there any thing I can do to ensure that both of them stay healthy? <<"Cards on the table", so to speak? Your fish are probably either of the Common, or Comet, variety. (Typical 'carnival' Goldfish.) These can grow to 12 inches in length and are generally best-suited for living in ponds rather than indoor aquariums. An indoor aquarium would have to be in the range of 90+ gallons to see these fish live long and thrive. You've already gone to extraordinary measures compared to what happens to most of these fish but, this is what you're faced with. Frankly, neither will do well for long where they are. My advice would be to find a "suitable" home for your fish. If you're intent on keeping them and, you have the room in your home, they'll need larger quarters.>> Thank you for taking the time to read and answer this long email. Your advice is greatly appreciated. Regards, Chen Yieng <<Please feel free to write back with any further questions you might have. My best to you. Tom>> Goldfish Acting Strange 9/6/06 Bob, I have a 10 gal fresh water tank - excellent filtration and oxygenation. All water levels test at very good to perfect. Over the last few days my goldfish (I only have one in there, about five mos. old) has been acting odd. She's been floating in her plants at the rear left corner of the tank, not eating much, and swimming erratically and very, very fast if anyone approaches - none of which she had ever done in the past. Last week, two of her plants were dying, ammonia levels may have been high. I did a full water change and washed all the tank decorations. I also got rid of the live plants and switched to plastic ones. It seemed to do very little as she's still displaying the same behaviors. Any ideas? Thanks in advance, Jessica < Check the ammonia levels. Sometimes when you do a very thorough cleaning you remove the good nitrifying bacteria used to break down the fish waste. So you may have to cycle your tank all over aging. Check the ammonia and be sure.-Chuck> Summat re goldfish color change 8/28/06 hi I was wondering if you could help me with my goldfish. it's fins are starting to turn silver, is it ok like this or is some thing wrong? <Please read here: http://www.wetwebmedia.com/FWSubWebIndex/gldfshbehfaqs.htm and the linked files above. Could be nothing, might be an influence of poor water quality, nutritional deficiency... Bob Fenner> Goldfish Problems 8/21/06 Hi. <<Hello, Kat. Tom this afternoon.>> I just got three goldfish recently, they're my first pets, and they seem to have something wrong. They are in a 3-gallon (US) tank with a mechanical and biological filter. They are all about 1 1/2 inches long with the tail (I should be getting them a bigger tank...). <<Very much agreed on upgrading the size of the tank, Kat. Glad to hear you're already thinking of this.>> I think all three are fantails (or some hybrid that look like fantails) and two have little white spots on their tails. I think they have ick? <<Sounds likely. Has the tank completely cycled yet? If not, this could be a strong reason for the Ich outbreak.>> They've been chasing around the third one which does not have white spots (one of the first two seems to be poking the third in the butt with its nose...). <<Trying to make points, perhaps? :) Actually, it's safest, from the standpoint of a "bully", to approach from behind. Kind of a Goldfish "sucker punch".>> They've all been eating normally (although the first two are a little more aggressive about getting their food). The third also has a damaged left fin. <<I don't want to accuse either of the other two but from what you describe, this may be due to aggression.>> They all have a line of small dots/holes(?) on both sides of their bodies from the top of the gills to the middle of the base of their tails. Is that normal? <<Absolutely normal. All fish have these. Anatomically speaking, it's called the "Lateral Line". Simply put, it's a sensory organ. Picks up electrical impulses and is useful in "echo-location" to aid the fish in relating to its surroundings. The lateral line is more apparent to us in some fish than others but, basically, appears like a line of "pores", i.e. the dots/holes that you refer to.>> I'm obsessively worried about these goldfish and very sorry for piling all these problems on you... <<No reason to be sorry at all, Kat. Other than clearing up the Ich and getting these fish into larger quarters, I don't see that you have a lot to worry about. The aggressive behavior of the "two" will, almost certainly, subside when everyone has plenty of room. Remember that these two are the ones with signs of Ich, as well. A bit stressful and likely to make them a bit "cranky".>> Is there anything I can do for my goldfish? I am feeding them TetraFin Goldfish Flakes and using Jungle Lifeguard All-In-One Treatment (I've taken out the activated carbon filter). <<The treatment is fine. You might look into the information on our site about Goldfish diet. They want, and need, vegetable matter in their diets and this should make up a big part of what they eat. High quality flakes are very good but all fish like variety just like we do. Also, don't forget about regular water changes. Goldfish are particularly "messy" not only in terms of what they don't eat but in terms of what they do eat...and get rid of, if you get my meaning. :)>> Thanks, Kat <<Any time. If you have more questions, please, feel free to write back. Tom>> Bully goldfish? 8/17/06 Hi, <<Hi, Emily. Tom this afternoon.>> I just got two goldfish the other day and I have been noticing some behaviors that seem odd to me. One of my goldfish (Elmo) is always pushing the other goldfish (Walter) around the tank. This happens mainly during feeding time but I've noticed it happening at other random times during the day. Elmo is slightly larger than Walter but they are generally about the same size. I'm not sure why this is happening or what to do about it. <<Might be "bullying" behavior, Emily. You don't say how large the tank is, which could assist a little. (You did say "tank" so I'm confident you don't have your fish in a "bowl".) Filtration, aeration, water parameters can also play a part here. I can't discount that "Walter" might just be a "Walter-ette" but the behavior would be unlikely at the juvenile stage unless the, hypothetically-female Walter, were mature. Young males are known to rub up against/physically contact females. "Firing for effect", in a manner of speaking. Isolating the "bully" is known to work with some fish. I don't care for the practice of placing the fish in a plastic container inside of the tank because it could lead to potential stress-related problems down the road. Has been known to work, though.>> Please help me. <<My recommendation? Patience and observance. Unless Elmo is a "rogue", I would offer that the 'aggressive' behavior will die down. If it doesn't or, if the behavior becomes even more aggressive, they'll have to be separated completely for Walter's sake.>> Emily <<Tom>> Goldfish changing color after being treated for ick 8/11/06
Hi <Hello> I hope you can help me. After only three years of fish
keeping I consider myself very much a beginner and despite looking on
the web I have not found an answer to this. I have a 55 litre tropical
tank. I have some assorted tropical fish but also two goldfish (they
started off this hobby when someone was throwing them out and I took
them rather than see them euthanized). <Mmm, not a good idea to keep
mixed...> As we have a stove in the room where then tank is located
it became very warm and after a year or so of that we thought we had
better buy a heater to ensure that if the stove went out our fish did
not die (I am just trying to explain why I end up with a mix of
tropical fish and goldfish) Anyway I take great care of the tank and
water quality etc and even just last week when I checked everything
with my test strips ph etc was all fine. However I introduced some new
fish a few weeks ago and I think that the water they came in may have
had ick in it because my two goldfish are now showing symptoms. I have
checked and it is classic ick, not male breeding spots. I read about
adding salt to the water and did so. I also got Jungle ick guard and
after a partial water change and vacuuming the gravel I added it in the
correct dosage last night. <Good> However this morning I notice
that my two goldfish have discoloured tails and fins. Is this normal or
have I done something wrong? <May be stress marking from the
medication... the ingredients are actually quite different in their
effect depending on water quality... rather toxic in more soft, acidic
(and warmer) water> I would really appreciate your help Claire Kelly
<Mmm, but some "genetic lines" of goldfish are also much
more easily given to changing color... Best to continue with the
treatment regimen here... But I would separate the goldfish and
tropicals ultimately. Bob Fenner> Goldfish odd behavior -
8/10/2006 Hey there crew, <Hi - Jorie here with you this balmy
Chicago evening.> My name is Julianne and my boyfriend and I have
two fantail goldfish named Paco and Tyrone. <Love the fish
names!> Tyrone is the one with the black stripe on his head and Paco
is the one with the white wave on the side of his body. The Plecostomus
in the picture died a few weeks ago, so it's just them two in our
5g hex tank. <All of these fish will eventually outgrow a 5gal.
tank. Better to save your money for a larger tank setup than add any
other fish.> Along with the bio filter that came with the tank, we
installed an underground filter for a couple reasons: to keep oxygen
levels high and to speed the growth of good bacteria.
<Overfiltration with messy goldies in a too-small tank is definitely
a good idea.> We've had P&T for almost 5 weeks now. The
hardest part was the initial cycling and controlling the
ammonia/nitrite levels. As first time fantail owners, we are proud to
have gotten this far. Ammonia and nitrites are at zero. Nitrates are at
20ppm. <Glad your tank is cycled. In the future, consider doing it
fishless, with only a bit of fish-food. Much easier on the livestock.
Right now, nitrates are at the high end of OK, so do keep a close eye
and keep up on water changes. As mentioned above, and as you likely
have seen, goldfish are poop machines!> Total hardness is at 120ppm.
Total alkalinity/buffering capacity is at about 100pm. pH is at about
7. <Sounds OK. Remember, too, that stability is better than exact
precision when it comes to water chemistry.> We've been good at
carefully monitoring the guys so that we can pick up on any weird
behavior. <Excellent!> Paco has a little trouble swimming perhaps
because his belly area is slightly bigger on one side. We thought that
he may be having swim bladder issues so we added peas to their diet
(which initially was just flakes). <Sounds good. Although I
don't personally keep goldfish, I understand they have a tendency
to get constipated, and peas will definitely help with this. Hopefully
the fish accept them as part of their diet...> He usually floats
with his rear end up when he's sleeping. Tyrone is the better
swimmer and is overall healthier looking. There has always been a few
gold dots on his backside--is this normal? <I've looked at your
attached picture and don't see any obvious signs of trouble.
Overall coloration is good, too. As long as the fish are swimming and
eating normally, I wouldn't worry - plus, as you indicate, these
"dots" have been present since beginning? The only thing I
can think the dots may be, if not normal, are velvet...but you would
likely have many more than just a few. It would be like a fine blanket
of gold dust on the fish...> He used to obsess over wiggling against
the tank or against the rocks, but he hasn't done that lately.
<Do a search to find what a picture of a fish affected with velvet
looks like - it can cause the fish to scratch against objects. If you
suspect it is velvet, you will want to immediately quarantine Tyrone
and start a treatment with copper sulphate. Also, raising the temp.
just a bit can be helpful. Unfortunately, once a tank is infested with
velvet (or ich), it becomes nearly impossible to get rid of, short of
breaking the tank down. Do you have any other tanks to transfer these
fish to? Basic rule of medicating, as you likely know, though is not to
medicate the main tank.> Today my boyfriend noticed Paco sitting
below our live aquatic plant and sitting on the gravel. He has never
done this before so we were pretty concerned. Is this swim bladder
infection, some other internal infection, or an external parasite? We
did a 20% water change just to be safe--but we still don't know
what it is... <Water changes are always good. Let me as you a couple
of questions: does Paco still appear bloated? Does he sit constantly,
or does he still swim and eat? He could be mildly constipated, in which
case I'd increase the frequency of pea feeding. Also, I've read
that with flake food, goldies can tend to gulp a lot of air along with
the food, since it is sitting on the top of the water...consider
changing to a sinking goldfish pellet. Hikari and Spectrum New Life are
two quality brands of dried fish food that I like to use.> Tyrone
has developed a habit of sucking air from the top of the tank (which I
learned was normal), but because of this, he has air bubbles in his
poo! <Again, the sinking pellets may help relieve some of this.>
So this is our analysis. We just don't want to medicate them until
we know what needs to be treated. <Good plan!> This is where you
guys come in... Thanks so much in advance! I do all my goldfish
research on your website. <I, too, love WWM, but remember that
it's never bad to seek out multiple opinions...I've got a
reference library of about 10-12 fish websites that I check when I have
a question. You'll soon learn, if you haven't already, that
every fish "expert" has his/her own opinion of what's
going on. Basically, I just look for the most common opinion and then
add a little of my own common sense to the mix...> Most of the time
it's helpful, but there are so many of these darn emails to sift
through! <Yes, searching through WWM can be a challenge, I agree! In
any event, look Tyrone over closely for velvet, especially in his gill
area. Based on what you report, it doesn't seem to be this, but
obviously you are there with him and can better tell. Also, consider
the feeding suggestions I've offered above to relieve the
swallowing air problem. Keep up with your water testing and make sure
to keep Paco and Tyrone's water clean. Again, you will need to
eventually upgrade their tank - they will undoubtedly outgrow it.>
Hope to hear back from you soon, Julianne <Hope I've helped,
Julianne. Best regards, Jorie> Headstanding goldfish - 8/9/2006 Hi I have written several times, and the help offered has been useful. I have another problem with one of my fish. Moby the goldfish has not been himself the past 24 hours. He hovers at a 75 degree angle to the base of the tank, head down. <Not good> This morning he has started to rest head down on the top of the pump head. He appears to eat normally (gannet like and first to the top as usual). He is a little quieter than normal. The tank is approximately 70 litres, and contains a comet and 4 minnows. We do a 25% water change each week, with PH, ammonia, nitrite and nitrate all within normal levels, as listed on your site. I add some aquarium salt to the tank each water change, following the correct dosage as on the side of the box. I also treat the tap water with King British Safe Guard, and add Tetra Aqua Easy Balance and Nutrafin biological aquarium supplement in the correct doses. The tank has an undergravel filter <Not the preferred filtration with goldfish> and a pump head with tube attached to aerate the water. I feed the fish on a mixture of goldfish mix (frozen helpings of daphnia, bloodworm, and vegetable matter in a small block), daphnia, spinach, Mysis, and vegetable mix - all frozen and defrosted as needed. <Very nice> I rarely feed flakes, never more than once every 2 weeks, and feed only once a day. The fish also have live plants to nibble on in the tank. <Very good> Any advice would be greatly appreciated. I really don't want to transfer him to the hospital 'tank of death' (named because all fish that have gone in have never come out!!). Paula <It may be that this goldfish has developed some sort of "fatty degeneration" internally from being "too well fed" on high-protein foods... and the cure will be to simply feed less or to turn to foods with a much lower protein concentration (less than 20%)... It could be that the fish is experiencing some form of gut blockage and that the trapped gas is causing a loss in orientation... here I would treat with Epsom Salt: http://www.wetwebmedia.com/FWSubWebIndex/saltusefaqs.htm Lastly in my "best guess" choices will be some type of gas bladder damage... Goldfish, minnows in general, the lower teleosts/advanced bony fishes are physostomous, have the ability to take in, release gas from this bladder via the mouth... but there can be instances of constriction internally... these are very hard to "cure"... but may be related to the first two possibilities. Bob Fenner> Goldfish growth and size question... sys. 7/31/06 Hi, I have not seen this exact question answered on your site but apologize if it's redundant. We have 3 new goldfish, 1 common and 2 comets; they are about 1 inch not including their tail. They are doing well and very active. They are in a 20 gal tank with a "Penguin Bio-Wheel 150" box filter that hangs on the side of the tank. Also a bubbler and gravel, decorations. No real plants yet. I understand from reading your site's info that the tank they are in is too small, <Will be ultimately, yes... But should be "large-enough" to allow dilution, cycling of waste, psychological and physiological space for now...> anyway we knew that they would ultimately outgrow it and we'd have to get them a bigger home. (My son is very attached to these fish so we could not give them away but would have to buy a bigger tank.) How soon should we be planning to get a new tank? <Likely a year or so... growth rates can be sped up, controlled to a point by feeding amount, frequency... partial water changes...> Is this something we need to do immediately or could we put it off for a few months? <The latter> How long do they live and how fast does it take them to get to be 12" whoppers?? <Can live a few tens of years... and won't get this big in aquarium settings... would take a pond, several years there> Also--I read something that said goldfish keepers do a 90% water change once per week, and some other info that says a 25% change once per week-- <Better to limit these chances to this last maximum percentage> and another source advising 10% change at least several times per week while the tank is just getting established. I've been checking the water and changing 10-25% of the water every day or every other day What do you recommend? thanks for answering, Nancy <Please read here: http://wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm Bob Fenner> Help! Jumped Goldfish... 7/28/06 Hi Bob - My poor 2 year old comet, Ali, jumped out of the tank yesterday and I found him on the floor when I got home. He's the only one in a 2.5 gallon tank. <Too small...> I have no idea how long he was there. His gills were still moving and one fin but his body was all stiff and turning white in color. I put him back in the tank immediately. He had a fine white film shedding off his entire body, he seemed to get a bit better through the course of the night. He was able to use all fins and tail again and seemed to be limbering up slightly but seemed to have trouble eating and moving around a lot. He's normally a very hyper fish and jumps a lot. Well this morning we went out to find him against the holes in the tube that take in the water for the filter. It seemed he didn't have enough strength to fight against it so we turned off the filter (the filter is a new addition to the tank so he's used to not having it.) and moved him out of the spot he was in, he seemed to be stuck. When I left him today he was laying on the bottom on the rocks but he was still breathing and looking around. I'm very, very upset. The pet stores have not been helpful at all. Is there anything I can do to save him or was it already too late when I left him this morning? <There is some hope. I would medicate this fish with a bit of aquarium salt> Any information would be so so helpful. Thank you in advance. Saraiel <Please read here: http://wetwebmedia.com/FWSubWebIndex/saltusefaqs.htm Life to you. Bob Fenner> Stunting <Gold>Fish 7/25/06 Hi everyone, <Hi Sarah, Pufferpunk here> First of all, you guys are great. I am finding out loads about everything aqua on here, and am having a blast. <We aim to please!> I have spent hours popping around, trying to satiate my addiction but alas I fear it has grown worse! <Boy, does that sound familiar! I now have 8 tanks totaling 440g & looking to upgrade...> Anyway, while going through things I came up with a question I couldn't quite find an answer to but first, the background: Like many other people, I too started out with goldfish, when I was much much younger. In fact, it was one of the infamous carnival comets! (Doe!) That of course died and I got a couple of fantails which I kept in a small (20 tall) aquarium. Also, when I got these, I purchased a book on goldfish, following my then and still remaining obsessive compulsive nature of wanting to know everything about something that interests me. In that book it talked about goldfish being carp and only growing to the capacity of the tank and did not mention this as being a problem. In fact, if I remember correctly, this quality was listed as being a positive attribute, making it an ideal starter fish. <Actually, GF are extremely poor starter fish. They are messy & produce a lot of waste/ammonia, requiring large tanks & huge weekly water changes. Serious GF keepers do 90% weekly. They can also live up to 30 years, growing over 1', in the proper conditions.> That was many years ago, the aquarium has since been broken down and resurrected again, this time as a tropical aquarium. Those fish died, though of what I honestly do not know since it was over ten years ago. My interest in the hobby has grown and I was toying with the possibility of a small outdoor pond, maybe of the half-barrel variety. This would probably be 30 to 50 gallons, depending on what I might find. <Lots of pond info at WWM.> Now finally for my question: you guys continuously say on this site that goldfish MUST have a very large, over fifty gallons, tank to remain healthy. What changed? <Nothing, I've known this for many years. There is tons of poor info out there.> Have we learned more or is allowing these fish to grow to their full size now considered more humane? <Of course! Would you like to be squished into a closet your whole life? how long could you survive? Don't you think you'd get depressed & eventually just quit eating, wanting to die?> You speak of "stunting" the growth but unless it causes structural abnormalities (besides the obvious dwarfism) why is this really a problem? In many ways, I see it as an advantage that a fish that can grow big but is bought small because "it was just so darn cute" can remain small, rather than the usual death because the fish grows to the size of it's container! <In the words of the wise scientist Robert T Ricketts: "Personally, I think there is a lot more to stunting than just one or two big items. Fish health and the ability to reach full genetic potential depends on a multitude of factors -- including the genetics, a healthy near-environment (basically water quality for fish), an appropriate environment (this includes décor, swimming space, refuge, current, lighting), and suitable food in sufficient quantity but not in excess. You need to know how big the fish should be (Fishbase is a reliable source for this), what sort of water and physical environment the fish lives in and what its lifestyle is -- schooler, lurking predator, active hunter predator, whatever, whether or not it allows or even may need conspecific or perhaps dither tankmates, or none at all. Any of these can and likely will change during development for any given fish. Tank size hits several of these points -- it allows for areas of current, for visually complex setups to explore, and space for swimming. Plus, it plays on PP's signature line of 'the answer to pollution is dilution'. With increased water volume, pollutants of whatever type will be at lower concentration than the same bioload will give in smaller quarters. Many or most fish seem to like areas of current, many do 'play' or exercise in the current. Hunters get some just by exploration of a complex environment. Schoolers (Auriglobus when young, Colomesus throughout their life) absolutely must have it or they will show 'caged animal' stereotyped behavior just to work off activity normal and in effect hard-wired into the animal. Fish need exercise. All mobile animals need exercise. Koi kept in shallow ponds do not develop normal configurations. They are too long and slender. They need depth as well as length and width. Without exercise, muscle mass will not be in normal proportion to frame and internal organs. Fish need to have whatever exercise they are willing to do to allow normal physical development. The space or volume bit has impact here as well. Pollution, whether from metabolites or hormones of general organics, suppresses normal growth and development. What levels of which are important? We do not know. We do that it varies from family to family for various pollutants over a substantial range. It is highly likely to vary from species to species within a family. In the best of all possible worlds, tanks would all be a high multiple of the length of the fish housed there. In reality, we rarely can provide that other than for the smallest fish. But we try to just as much volume as we can. We provide both current and relative calm, without having totally dead areas, in the tank, and we match the décor to the lifestyle of the fish. Naturally, we feed both well and wisely. We meet the fish's nutritional -- and for the special needs of different species-- and physical food suited to the particular fish. We provide enough to allow the fish to grow normally, but not so much that the fish is obese. Obesity is as great an issue for fish as for people and dogs. Too much food, not the best food, and feeding too often, all lead to problems. Water quality I'll assume as a given. Un-oxidized metabolites (ammonia and/or nitrite) are never detectable, oxidized metabolites (nitrate) are as low as is practical for us to provide, but certainly below 40 ppm nitrate, better below 20 ppm, best at or below 10 ppm. Organics are kept low by large water changes at sufficiently short intervals that hobby testable water parameters are never far off from the source water used for the tank (whether tap or processed or otherwise modified). That means the water you remove should be quite close to the water you will replace it with, excepting perhaps the nitrate titer, and the organic (which we cannot measure). IF you can provide all of this, your fish will, on the average, exceed the normal lifespan of the species in the wild, and frequently will be as large as if not larger than the wild counterparts. Anything less is stunting. Anything less will result in lower health and shorter life. To me stunting is insufficient space, improper diet and exercise, and both chemical and physical environmental deficiencies. Any or all of those lacks can contribute. Any or all can result in a stunted fish." Here is the entire thread I got this from: http://www.thepufferforum.com/forum/viewtopic.php?t=4030&highlight=stunting Sorry for the lengthy question, you guys are great for your patience! <Long response for a lengthy Q! ~PP> Sarah Goldfish with laboured breathing 7/19/06 Hi, <<Hello, Kate. Tom>> I have looked at other sites but with fish it is so hard to tell what is wrong. I don't want to treat my fish with the wrong thing and kill it. <<Very wise here, Kate.>> First of all I admit that I could have been more frequent with the cleaning of my tank. The fish is a common goldfish and he is about 13 years old. He is generally quite hardy. I cleaned the tank at the weekend and got some new large (smooth) stones and a plant for his tank. This was on Saturday, he seemed fine until last night. At around 9pm (just over 12 hours ago) I noticed that he was gasping for air near the top of the tank. I thought it was strange because he didn't have his mouth "out" of the water although his back fin was. However later he swam to the bottom and has mainly stayed there breathing heavily throughout. I wondered if he could have a balance problem but he is the right way up and can swim when he makes a big effort. <<By way of information, Kate, oxygen concentrations tend to be higher at the surface because that's where "oxygen exchange" takes place. Gulping for air (sometimes referred to as "piping") is the result of a variety of problems that usually stem from poor water conditions. Something here took several days to manifest itself, though, so I'm of the opinion that something related to but, outside of, the water change/cleaning is responsible.>> The thing is that I know he's sick because normally when it's time to be fed he swims straight to the top of the tank but now he can't move fast enough and is concentrating on breathing all the time. From what I have read could it be bacterial gill infection? <<I can't exclude this. You haven't given specifics regarding how long it's been since you cleaned your fish's tank so it's entirely possible that you "stirred up" a fair amount of "stuff", shall we say, when you accomplished this. The thought of rotting detritus/mulm being "inhaled" by your Goldfish makes me a little queasy so I can only imagine how he must have felt about it. ;)>> It just struck me as strange that once he was cleaned out he was fine but that it came on last night, 3 days after cleaning out the tank. Could whatever is wrong with him have still been caused by the water quality before the tank was cleaned? <<Could be but ask yourself if this situation would have been forestalled if you had waited another week. He was fine until the cleaning so something was precipitated by this. I suspect that I know the answer but, did you "quarantine" the plant? Parasites such as Ich will "hitchhike" on plants as readily as other aquatic life. Also, how thoroughly did you wash the new gravel before placing it in the aquarium? This, frankly, is what I have some suspicions about. pH levels typically drop in aquariums over time. With "regular" water changes, these fluctuations are minimal and have little, if any, adverse affect. However, throw in a large water change along with the addition of new substrate, potentially leaching pH-increasing minerals, into the tank and you've got a good case for pH shock.>> I have removed the new plant and the stones from the tank and have changed a lot of the water. <<Good on the removal of the new items but slow down on the water changes. You didn't mention anything about testing the water conditions so I have no idea what's currently going on in your tank. I'm thinking that you don't either. Invest in a test kit, Kate, or take a sample of water up to your local fish store for testing. Find out exactly what's going on in your pet's aquarium. Adaptive as they are, you're probably putting a lot on a thirteen-year-old Goldfish.>> I will readily admit that I am really not the best fish keeper and to be honest the fish has probably lived this long more because of luck than anything else. I am asking for your help because I don't want him to die and I don't want to do something which could make his condition worse. <<Nothing wrong with a little luck, Kate, but we can certainly "hedge" our bets. Again, find out what the parameters in the tank are regarding ammonia, nitrite and, especially, nitrate and pH levels. Aquarium salt at the rate of one tablespoon/five gallons of tank water can greatly assist in oxygen uptake - dissolved first in fresh, dechlorinated water.>> Many thanks for your help, Kate <<Always happy and ready to do so, Kate. Please get back to us if you need more input. Tom>> Kate Hopkinson Red Cap Oranda - Red is fading 7/15/06 Hello, <<Hello, Dan. Tom with you today.>> I have had a Red Cap Oranda for one year and just recently the "redness" of the cap is fading. In fact, it's almost entirely gone now! Apart from that, the fish seems perfectly healthy - swims well, eats well, etc. I have another Red Cap Oranda in the tank and that one is fine...at least for now. Any thoughts? <<Coloration changes in Goldfish are not uncommon particularly during their first year. While I've not run across your specific situation there are several factors at play including genetics, diet, exposure to sunlight and age. Since your pet appears to be quite healthy otherwise, and your other Red Cap hasn't (yet) shown any signs of the same thing happening, I would suspect a genetic predisposition to the fading and/or loss of color. Something of a more "hands-on" nature might be to investigate supplementing your Orandas' diets with Spirulina algae. The carotenoid pigments in Spirulina have been reported to significantly enhance the coloration in Koi and Goldfish so, if you feel like doing a little "dabbling", it might be worth a shot.>> Thank you very much, Dan Feins Beverly, MA <<My pleasure, Dan. Tom>> Black moor beh., sys. 7/5/06 I made an outside pond over the winter and put in some goldfish, koi, two shubunkins, two fantails and two black moors in April. They all seemed to be doing fine and getting along with each other. <Mmm, "fancies" are best not kept outdoors generally, and most often can't compete with Comet goldfish, Koi over time...> A few days ago one of the moors turned white around the edge of all its fins. Then it developed bleached out looking sides and its head is turning bright orange. I thought it was spawning because several of the goldfish were chasing it all around the pond. That has stopped. It is still eating and swimming well but the bleached out sides and orange on the head seems to be spreading. Any suggestions or advice would be greatly appreciated. <Moors can/do change color at time... more so in "outdoor", changeable water conditions, but the chasing behavior is likely unrelated.... can be trouble, is likely related to breeding... I would separate this one fish, actually both moors and fantails... bring them indoors, keep in an aquarium. Bob Fenner> Goldfish Growth Rates 7/4/06 <<Hello, Paul. Tom>> I'm housing a pair of 3" comets in a 30"x12"x12" tank (~20 gallons) running a Millennium 3000 filter (295 gph) and using 1 tbsp aquarium salt per 5 gallons. <<Having read through your post, I know that you're already aware that a 20-gallon tank is too small for these fish. I commend you on the level of filtration, though. Very good!>> I feed Hikari pellets twice a day, a supplement with blood worms, shrimp, peas, and lettuce. In the two months I've had the fish, they've only grown about 1/2". <<May not be out of the ordinary here, Paul. Temperature and size of the environment are factors that determine growth rates in these fish, as well as their diets. For instance, while we think of Goldfish as "cold water" fish - they are by "tropical" standards - they'll do very well at temperatures in the mid-seventy range (72-76 degrees). In small aquaria, while not stopped entirely, Goldfish growth will be slowed significantly. I might suspect this to be part "evolutionary" since large animals would quickly be poisoned to death in their own waste in "cramped" quarters.>> I've heard goldfish are supposed to grow "quickly" - what are the typical growth rates I should expect from my goldfish? How long will it take before they reach 6"+ and justify the 120 gallon setup I've been eyeing? <<My opinion? Your Comets probably would not reach 6"+ in a 20-gallon tank. That isn't necessarily a "blanket statement" but I think it entirely possible that you could lose them before this size was achieved. The type of fish you have "mandates" a 60-gallon tank, or larger, even at this point of their lives. As for "justifying" the 120-gallon aquarium you already have your eyes on? If that's what you have your heart set on, there shouldn't be any reason to justify it. Besides, your fish will thank you for it! :) Tom>> Paul Uncycled system for goldfish? 7/2/06 hi please can you help me. we have recently purchased 2 goldfish for our daughters birthday. we bought the tank a week before we bought the fish so that it would be ready for when we brought the fish home. however we brought the fish home and they seem to be constantly attacking each other. Is there any reason that the fish should act like this. i am very worried that they are trying to kill each other. Or is it normal and they are playing. i have never noticed anyone else's fish acting in this way. Thank you Kristine. <Perhaps just too crowded, but likely this tank was not, is not completely cycled.

Bob Fenner> Goldfish attack! 7/2/06 Hi, Just before Christmas a Heron ate most of my goldfish in my garden pond. All that was left was a small Koi and a couple of fairly large goldfish. <Happens> This Spring I introduced replacements, quite small Koi carp, goldfish and shubunkins. Everyone seemed to be getting on ok, but now the largest of the goldfish has started attacking one small shubunkin and one small Koi. <Also... unfortunately> It has quite literally eaten the tails of both down to the roots and I fear they will not now survive. How can I stop the big goldfish eating the smaller fish? <Move or destroy this fish> The pond is currently besieged by tadpoles but I can't see this as a factor? <Me neither> There is plenty of space in the pond for all the fish. Appreciate any help you may be able to offer. Many thanks ADS <There are just some "mean", rogue individuals... "Mad dogs" and goldfish... Bob Fenner> Possible Bully Goldfish/ New system - 6/29/6 I encountered an emergency fish situation this weekend. <<Uh-oh!>> A friend literally left the following on my front porch: 3 orphaned goldfish in a Tupperware container of untreated tap water, a reject can of goldfish flakes, and a 10 gallon tank that was filtering sludge and was 60% covered with algae. <<Oh gosh, you must be overwhelmed.>> Prior to Saturday, I had no aquarium. Now, a true novice, I have a 20 gallon tank (with a 30 gallon filter) and 3 goldfish. I realize this is too small for the current stock, but spatially and financially this was my option. It is twice the size they were used to. <<It is certainly an improvement, and will do for some time. http://www.wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm http://www.wetwebmedia.com/FWSubWebIndex/gldfshmalnut.htm>> I was surprised at the size of the fish. From tip to tail, the fantail "Bubbles" is about 3 inches long. The common "Beluga" is about 4 inches. And the comet "Beethoven" is about 6 inches. <<They will get much larger.>> They are beautiful fish and appear to be healthy. A miracle, I'm sure. Because of the urgency of the situation, I assembled the tank, let it run 3 hours, floated the fish in separate bags for 10 minutes, added aquarium water and floated for another 10 minutes, and set them free. <<The tank is not cycled. Please read here: http://www.wetwebmedia.com/FWSubWebIndex/fwestcycling.htm. You're going to have to do mega water changes (75% daily) to keep the ammonia and nitrite from building up. I recommend a dechlorinator such as Prime be used, added to your replacement water.>> They've survived and seem to be doing well. I'm feeding them Goldfish Crisps. Here's the problem: The common is constantly chasing the other two fish. He may nip at them, but I don't see any damage yet. (That comet is really fast and doesn't tolerate the common being very close.) As far as I know, these fish have been together since "the beginning" -- whenever that was (surely several months, by now -- they have quite a history, I won't bore you with the details). I have read many posts concerning bully fish, but this one seems to be unique. Could the size of the tank really be the problem? <<Yes. It likely is in this case.>> Or could a chemical imbalance be causing his aggressive behavior? <<Very doubtful. Hopefully in time, with improving water conditions, things will improve.>> There is a strong ammonia smell near the tank. I have not had the water tested since it's only been 3 days. <<That's not good at all. You should get on those water changes. Also, you really should purchase test kits of your own for at least ammonia, nitrite, and nitrate.>> Help! I don't have a place to put the common if separation is necessary; and strange as it may sound, I've already become attached to the trio. <<That's not strange, they are pets!>> However, I want to do what is best for my fish. Any suggestions would truly be appreciated. Thank you! Krista <<I really do think a larger home is in order, but at least please correct the water parameters.>> P.S. Is it best to simply trash the home they arrived with or is there something worth salvaging? (I already tossed the filter. The hood is covered with mold. The tank is really covered with algae and reeks.) <<A thorough cleaning (no soap) will do. I'd keep it. If you need to, you can use it to move on of the fish if aggression gets too bad, and an extra tank always comes in handy. Happy reading! Lisa.>> Bubble eye goldfish beh. 6/28/06 Hello! I'd like to thank you for all of the help the site has provided over the past year. I do have a problem and have searched with no luck finding an answer. I have a bubble eye goldfish. He's over a year old and huge (about 6 inches). When we first got him (or her) one of his bubbles popped but healed up quite nicely, it inflated again, but it never got quite as large as the other bubble. <Happens> The problem is that the one which has not popped is quite large. He appears to be trying to eat his own bubble! It is very disturbing to watch. He constantly tears at it (the same manner in which he would tear at a piece of zucchini). It appears to be bothering him, well I realize he isn't that smart, he probably thinks its food. Is there anything I can do? Is there anyway to safely "pop" his bubble using a needle. I fear if he does tear it open it will be a more severe tear and will not heal. Any suggestions? I hate the thought of doing this, but he is eating his own face. Thank you, Kris <I don't know that there is an easy solution here re popping the one eye "bubble"... I suggest adding some small fish as a distraction (to "give this fish something else to concentrate on"). Perhaps some platies or Whitecloud (Mountainfish). Bob Fenner> Goldfish questions, young not-yet reader 6/27/06 Hello WWM. My name's Amanda but you can call me Mandii. Everyone does. But that's besides the point. I have just bought 2 Shubunkin goldfish and I have some questions about them. Here we go: What is the life expectancy? <Can live to be twenty years of more given good care, environment, feeding...> [When owner is not neglecting] How can you tell what gender the fish is? <Please read here: http://www.wetwebmedia.com/FWSubWebIndex/gldfshreprofaqs.htm> I think I might have bought one male and one female Shubunkin so: How can you tell if one is pregnant? How can you tell that they are spawning/mating? <See, read the above area> When both of the Shubunkin lay/rest on the pebbles on the bottom of the tank together, what does that mean? <Not a good sign... perhaps just "tired", settling-in... but also an indication of poor environment condition> Thank you so much for reading this message. I await a reply. Thanks again! Sincerely, Amanda J. Schneider [Mandii] ^_^ <And here: http://www.wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm and the linked files above. Bob Fenner> Goldfish chasing: Is it
bullying? 6/26/06 Hi, <<Hi. Tom>> I got my new
fish and 10-gal tank about 2 weeks ago. I've stocked it with a
comet goldfish (3 inches), 2 common goldfish (little over 2 inches
each) and 2 shubunkins (also a bit over 2 inches each). <<Too
little of an environment for one fish of this type let alone five! Six
to seven times larger is needed, minimally.>> The problem is that
the comet is acting like a bully (I think) because he/she chases around
the 2 common goldfish a lot, and now 1 of my c. goldfish is acting like
him and chasing around the only one of the shubunkin and the other c.
goldfish. <<Your tank hasn't "cycled" in two weeks.
Almost certainly, they're exposed to ammonia which is toxic/deadly,
to fish. Soon, if not already, they'll be exposed to nitrites which
are also deadly to fish. The "stress" factor will be enormous
and create behavior that these fish would not normally exhibit.
They've already become susceptible to disease and
infection.>> I need a little help in knowing if this is playing
behavior, some sort of mating behavior or if these fish are becoming
harmfully aggressive. Or maybe do you think my tank is too small for
these goldfish? I could use as much advice as you can give. <<Our
site offers more information than you'll ever need. First, research
"cycling". Then, research each of your fish. After that,
research more. You already sound like you have a "handle" on
behavioral issues with your pets. When you have specifics, we'll
talk more. ;)>> <<Tom>> Blue light & goldfish beh. 6/13/06 Hi Friends I live in India, and has been using your website quiet a lot. Some of the members of our website have reported that their Oranda turn upside down when blue light is turned down. These are apparently healthy fishes and resume swimming 2-3 days after blue light is switched. <Unusual... light/ing should have little effect here> This has been reported by two separate persons, one uses a normal blue bulb and other one uses blue "actinic lights". This happens only with Oranda only and other fishes are unaffected. Thanks S. Raghuvanshi <Something else is likely at play here... most probable is nutrition... the sole feeding of dried-prepared foods.

Bob Fenner> Re: Strange Goldfish Behavior - 06/02/2006 Hello again, Tom. <<Well, hello again, my friend.>> Please excuse me for not including this with the e-mail I sent to you a little while ago. <<I hope others are taking note of your impeccable manners. :)>> I have a couple of questions regarding Mimi's behavior. Is it normal for Goldfish to twitch or display what appears to be tic of sorts? <<Normal? I would say not...>> Ever since I have had Mimi she has, on occasion, displayed such behaviors. A fin will occasionally twitch or beat very rapidly or, when restful, will at times twitch her body to the side, quasi-spasmodically. She also yawns at times; opening and extending her mouth as if whistling intensely. <<A happy tune, perhaps? (I'm teasing you, of course.)>> Other times she opens and closes her mouth as if stuttering. She is otherwise fine. Does this sound alright to you? <<We can't discount her "genetic" make-up, Alfredo. Would I say this is normal behavior for a Goldfish? No. Is it normal for Mimi? Quite possibly and, probably, truth be told. Unless you've seen signs of a problem, I would consider this as "just the way she is". The funny thing is that we like our fish to have different personalities, and behaviorisms, up until we become worried about their health. At that point, we want every fish to be alike so we know exactly what to do for them. All fish aren't alike, though. (It would sure make our jobs easier they were!) I'm inclined to think that Mimi has these "eccentricities" because "that's the way she is". I've an Angelfish in quarantine (again) that doesn't seem to want to get "with the program". Active, attentive and would sit in my lap, if possible, but, is about one-third the size of the other two. Just the way it is.>> I appreciate all your help, Tom. Thanks <<You're always welcome, Alfredo. Tom>> Goldfish Getting Lazy - 05/05/2006 Hello, I was wondering if you could help me. I have a 9" long goldfish that was won at a fair about 3 years ago in a 55 gallon tank. He has always been healthy, until about 3 days ago. I noticed that he has been laying around at the bottom of his tank and won't eat. I tried doing a 50% water change and changed his food. But this morning he is still laying at the bottom and not eating. When I was cleaning his filter, I also noticed one scale in it. But when I looked very carefully at him, I was unable to see where it could have come from. He still has his beautiful orange, black and silver. Do you have any suggestions? Thank you. -Lucy < This could be the beginning of an internal bacterial infection. Do a 50% water change, vacuum the gravel, clean the filter and treat with Metronidazole.-Chuck> Lethargic goldfish hanging around vertically 4/30/06 Hi. <<Hello, Linda. Tom>> I've been reading through some of the posts, and I don't see anything about this. I've had two common goldfish (the kind given away at carnivals and such) for about 7 years. One is golden orange, and the other is almost all white. They have been doing very well (except for a few bouts of high nitrates) in a 25-gallon tank with a TopFin 40 filter, a six-inch airstone, and a lot of frilly live plants. They've grown to about a foot long each. I hang a Nitrazorb packet under the flow from the filter to counteract the nitrates. I also replace about 5 or 6 gallons of water every week or two and replace the filter about once a month. I feed them BioBlend goldfish food twice a day. <<First of all, congratulations on your fishkeeping skills. Generally, I would recommend a tank twice the size of yours for two fish of this size which speaks well of the care you've given your pets. That said, there's something here that caught my attention. When you say that you "replace" the filter about once a month, I normally advise against this opting, rather, to "clean" the media in used tank water to preserve the beneficial bacteria contained in the filter media. Replacing the media outright requires re-seeding the filter with the bio-colonies needed to maintain optimum water conditions and can lead to spikes in ammonia, nitrite and nitrate levels, if only over a short period of time.>> Whitey often gets red spots and streaks and becomes lethargic - just hanging around vertically, nose up, swimming around a few seconds occasionally (especially after a nudge by Goldie) and then returning to the vertical hang. I've found that using StressZyme usually clears up those symptoms. But after I've used it a few days, and Whitey is doing fine, Goldie starts hanging around vertically instead. This has gone back and forth several times over the past year. Although it's not hindering their appetites, I'm assuming the lethargy (and the red spots and streaks) means they are not feeling well. Unfortunately, I can't seem to make them both happy at the same time. <<You don't include specific water condition readings with your posting and these are always important to us when trying to help with problems. Because of the "legendary" hardiness of Goldfish, I suspect that you're experiencing water quality variances that have, within the last year, begun to display themselves. What you describe is almost certainly bacterial hemorrhagic septicemia which is being "cleared up" temporarily by the addition of the water conditioner. Commonly this situation is caused by organics in the water and might easily be expected given the size of your fish in a 25-gallon tank. I would suggest that you stick with 20% water changes each week and clean your filter media rather than replacing it.>> Any suggestions would be welcome. Thanks. <<Hope this helps, Linda. Tom>> Re: Tom: Lethargic goldfish hanging around vertically 5/28/06 Thanks for your help, Tom. <<Glad to do so, Linda.>> The fish are both doing better. I've followed your suggestions, and I've also made one other change after reading some other posts on your site that I think may have made a difference. <<Good to hear about your fish. I'm glad you continued researching, as well.>> My son is a bit of a night owl. He frequently stays up all night with all the lights turned on. <<Uh oh...>> I hadn't thought about it before, but something in one of the posts gave me the idea that, since fish don't close their eyes, they probably need some dark time every day in order to rest. My son had been home on vacation when I wrote to you, and had probably been up all night with all the lights turned on every night that week. It's no wonder the goldfish were lethargic! <<No wonder, indeed, Linda!>> Now I'm wrapping black trash bags around the sides of the tank by 10 at night, just in case the lights stay on. <<Good move. You might also ask your son for some financial help with the electric bill! :)>> I am also cleaning the filter in water siphoned from the tank, as you suggested, but the media is getting rather frayed and the charcoal is not likely to keep the water clean if I don't replace it every few weeks. Is there something I can do ahead of time to condition the fresh charcoal and filter before I change it? <<As to the charcoal, no. Normally we don't recommend the use of charcoal unless it's used to remove medications from the tank after a session of treatment(s). Also, if you choose to continue using it and, there are some credible sources who advocate it's use all the time, you should replace it every few weeks, anyway. The old charcoal can't be reactivated, for those readers who're taking notes. Depending on the design of your filter, my recommendation would be to insert the new media next to the old media in the filter housing to ensure that the new media gets properly "seeded" before giving the old stuff the "heave-ho". If this isn't possible and, you can get your hands on a bottle of Bio-Spira (Marineland), you could simply insert the new media and dose the tank with beneficial bacteria to provide an alternate means of seeding the new filter. If this, too, isn't possible, put the new media in the filter and monitor your water parameters very closely for a couple of weeks.>> Thanks again for your assistance. Linda <<Happy to be of assistance, Linda. Tom>> Mesmerized Goldies... poisoned
4/26/06 Hey Crew, <Christopher> I changed my tank water after
discovering that the ammonia levels were way too high. Prior to this,
the boys swam around like maniacs, munching down each others offerings
& generally looking like they were having a good time. I checked
the water parameters (Temp = 68, 0 ppm for NO2, NO3, pH @ 7.4, ammonia
@ 4.0 ppm that I brought down to 0.50 - 1.0 ppm. <Still deadly
toxic> The end result is that now the boys spend a good part of the
day either at the bottom, transfixed to the end of the tank opposite
the filter. I stopped feeding them, <Good> & they seem a bit
"stoned." They respond to tank tapping, come up for food that
I won't give them. It just seems a little weird. Thoughts? --

04/17/2006 Hello! I searched the old FAQ's looking for a way to
tell if the white spots on the cheeks of a goldfish are ich or breeding
season indicators, <Hopefully the latter!> but wasn't able to
find a descriptive comparison. <We/I do need/want "good
pix" of most all commonly encountered such phenomena. Are you able
to make some digital pix of these and send?> My goldfish who is
about 3.5 inches long has little clear/white spots on his/her cheeks (
3-4 on one, 7-8 on the other) that come to a kind of point. I read in
one post that it is near impossible to tell the boys from the girls,
but just in case, his/her front fins have a sort of
"serrated" edge if that helps in figuring out if little fishy
in a he or a she. <Do think this is a "he"... if the spots
are as you describe, only on the cheeks> How can I tell if he/she is
sick, or if in fact, my fish is a boy, and the other goldfish is a
girl, and they are just about to do what fish do? They have been
swimming around each other and rubbing each other, and chasing too.
<Ahh! Even more evidence> If it is ich, is there a medicine that
can be given with snails in the tank? <Mmm, not as far as I'm
aware. All such treatments are deleterious to snails> Thanks so much
for all of your help in advance. Sorry if these questions are
redundant, I try my best in searching the old FAQs. The site is great,
and I appreciate it very much. xxx kuniko <Doh tashi mashiite my
friend. No worries. Bob Fenner>
