Question about yellow boxfish aquascape: Boxfish
systems\aquascaping 8/8/2009 Boxfish... sys., sel. Hello. I have always loved boxfish but assumed my tank is to <too> small. I have a 55 gallon reef with one Ocellaris Clown fish and a Bicolor Pseudochromis (soon to be removed). I have been looking into Ostracion meleagris, Ostracion solorensis, or Ostracion whitleyi as their size is much smaller than many boxfish. Is my aquarium still to small to keep a contented (one of the above) boxfish and are any of them reef safe (especially with clams)? <Yes> Ostracitoxin- I have heard that it only effects fish and other vertebrates, is this true? <As far as I know, yes> Could the effects of ostritoxin be avoided or at least minimized with a good protein skimmer and lots of activated carbon/a Phosban reactor? <Yes> I know that is the best to hastily remove cephalopod ink from an aquarium. Most places that sell Boxfish list them as "Expert Only," is this only because of their toxin or are they genuinely very hard fish to keep alive and healthy? If so, why? <Good question... likely in a word: stress... Ostraciids just don't adapt well to captive conditions... They're very likely "accustomed" (hard wired) to being in large, open water conditions... And not being able to swim away from troubling experiential phenomena, suffer for it> - Bad shippers, problems with getting them to eat, prone to disease, all of the above, other? <Yes> I'm sorry if I am asking alot <No such word> of questions; but I can not find much information on the subject and I would hate to buy an animal that I am ill equipped to keep, or not have an animal that would have worked smashingly with my system. Thank you for your help. <Thank you for your obvious research, sharing... Bob Fenner> Cowfish Mauled/Cowfish Compatibility 6/26/06 I have a 6 mo. 24g Nano that is running smoothly with various zos, Flower Pot, Cup Coral, Sun Coral, a Cowfish, Percula Clown, Firefish, banded goby, Sally Lightfoot, a Peppermint Shrimp, and various other cleaners. Problem...my Cowfish turned up the other day with a half eaten tail fin. Added some Melafix and he seemed to perk up and be recovering. This morning I discovered the cowfish stuck to the intake with a shredded side fin. Can't seem to get his equilibrium. Who could be the culprit? I thought Sally Lightfoots and Peppermint Shrimps are supposed to be safe. Any thoughts...my cowfish is recuperating in a quarantine tank but want to remove the offender quickly. I did watch the tank the other night, late, didn't see any mischief but the shrimp was standing guard. I will try you jar technique to catch the offender. <I'm putting my money on the Sally Lightfoot if the Cowfish problem isn't disease related. They are not to be trusted with slow moving fish such as the cowfish. James (Salty Dog)> Debra <<A cowfish in a 24 gallon world? Not for long. RMF>> Hashing, Boxfish size/sel., systems - 03/13/2005 Hey, I noticed in 1 of your replies on WetWebFotos that you are a hasher! I'm YIP ... Yes, I'm Pointing from St. Pete Fl, I've hashed w/ tbh3 & tbmah3. <Ahh! And I am Dogfish... a very old timer... who has hashed in many countries...> I'm looking up box fish ... I just started a saltwater tank & catch what I put in it. Just got a 6-8 inch box fish and a 1-1/2 inch box fish ... they are really pretty. How big do they normally get? <Depends on the species... the most commonly available are posted on WWM: http://wetwebmedia.com/boxfishes.htm> Just a "HI" from the other side of the states! Yip <Am actually out in HI (Hawai'i') right now... hashing with the Kona Coast HHH and doing the Lavaman next mo... have mercy! On out! BobF/DF> Puffer/boxfish/lionfish - 3/6/2006 First off I would just like to thank all of you at WetWebMedia for having such a great website with every possible answer to every possible thing which has to do with what we all love most, fish. I'm sure just about everybody asking you a question compliments you on your site, so I will get right to my points. The majority of my questions have probably already been answered. I have a 75 gallon set up right now with a nice 6-7 inch long lion fish (about 10 inch wide fins) and a Striped Dogface Puffer (still rather small 3.5 inches) My first question is how would a 5 inch Spiked Boxfish be in this aquarium? <<Absolutely not. Your puffer needs a MUCH larger tank as it is.>> I talked to my nearest saltwater store and they said it would be a good combination, mainly because all 3 fish tend to be slow moving and not aggressive towards fish that cant fit in their mouths. <<Most puffers find lionfish fins too hard to resist.>> My next question deals with feeding My Lionfish. Can I get by with just feeding him live ghost shrimp? Along with live brine Shrimp as well? <<No, both of these foods are very poor nutritionally.>> I am asking this because as dumb as I sound, I really don't like taking a part in having other fish be killed even though it's what happens in nature. I would just feel better off letting him eat live Ghost/Brine shrimp instead of Guppies/Mollies. I have Guppies and Ghost Shrimp in the tank right now and he probably ate 15 Guppies within a 10 minute period. <<Feeder fish are a bad choice as well. They carry disease, and are malnourished when purchased. Search on WWM for feeding suggestions.>> My next question has to do with any helpful advice you have towards trying to steer the lionfish away from live and start feeding him frozen instead. I am sure you have a link on the website already about this question. So I am sorry I am asking it again. <<Read on WWM>> My last question has to do with the growth rate of the Striped Dogface Puffer. I have had this little fellow for a little over a month now, and he might be getting a little more round but does not appear to be getting any longer yet. I read they reach around 10 to 12 inches in length. <<He needs to be moved to larger quarters ASAP to avoid stunting.>> Again thanks a lot guys for your time and I am sorry about the questions I asked that you have already answered. Hope to hear back from you soon. <<Enjoy your research. Lisa.>> - Peter Hawaiian Blue
Spotted puffer not eating 9/25/05 Purchased a Hawaiian Blue
Spotted puffer from an internet site over a week ago. Looked healthy on
arrival and still looks well with no visible parasites but has not
eaten a thing since arriving. I've tried flakes, krill, plankton,
pellets all with and without garlic added. <Mmm, don't eat dried
food/s... and generally don't eat after being shipped for a
while> He is housed in a 50 gallon FO tank <Too small> with a
small Picasso Trigger, Flame Angel, and Blue Tang. <Too crowded>
No one has been bullying him or troubling him since he's arrived.
<Psychologically... is very crowded> SG is 1.023, Ph is 8.2 and
ammonia, nitrates, and nitrites are undetectable. I have a HOB power
filter rated for 500 gallons per hour, an Aqua C Remora skimmer and 2
1200 Maxi Jets for added water circulation. Temp has been higher than I
would like at 84 degrees and I've ordered a chiller last week that
is yet to arrive. <... I'd cancel the chiller, put the money
toward a reasonable sized system... at least double... better quadruple
what you have> The other fish all appear well and are feeding well.
The puffer has been hiding in a cave but does come out about once a day
and make a slow tour of the tank. Moves slowly but does not have any
visible lesions and doesn't look emaciated yet. He was acclimated
over 3 hours via drip technique and then given a 10 minute freshwater
dip with Methylene Blue added before being added to my tank. <Good
technique> Any ideas what might be wrong here before I lose this
little guy? All comments would be appreciated. Thanks. John <Needs
larger quarters... stat! As they say on teevee... Try offering
whole/opened shellfish... and add vitamins to the system water. Do get
the larger system... ASAP. Bob Fenner> Shaw's cowfish/Arcana aurita AKA Striped Cowfish Hi Bob, <cheers, mate... Bob is away in Indonesia getting his face tattooed, his tongue pierced and his nails done. Anthony Calfo in his stead> My name is Sal and I have read your book many times over now. thanks for all that great info. I hope that you can help me. The fish is Arcana ornata. it comes from western Australia (coral sea). I am having trouble finding information. <www.fishbase.org is one of the best places to begin a search about fish... look here for yours: http://www.fishbase.org/Summary/SpeciesSummary.cfm?ID=14561&genusname=Aracana&speciesname=aurita > I want to provide this fish with an optimum environment at my home. <good, my friend... because like most cowfish it needs a species tank with no other fishes for many reasons beginning with the toxicity of its flesh> I think this fish requires cooler water. if this is true can my live rock and live sand survive? also, what sand stirrers and herbivores can I use in these cool waters? <I would not recommend the keeping of any other fishes in with this species for a casual display> what foods should I feed? <little is known about dietary needs here but a very wide selection of meaty foods will likely be necessary. At least have Gammarus shrimp, Mysids, Pacifica plankton, shredded krill and occasional live ghost or grass shrimp> what other fish are compatible? <none... it would be perhaps irresponsible to keep such tank mates for the severe toxicity of cowfish when nipped or disturbed. You will need to always have water ready on hand for a complete water change too to spare the fishes life if it should ever exude in the tank for other reasons (temp spike, filter trapping, etc)> I know I have a lot of questions. I do trust your information so that's why I come to you. Any info would be greatly appreciated. Thanks a lot, Sal <I would strongly recommend avoiding boxfish and cowfish of any kind unless you are fully interested and prepared to set up a dedicated tank for them. The risk and labor to keep them healthy are significant. Perhaps just admire them from afar :) Kindly, Anthony> Help with cowfish (06/21/03) <Hi! Ananda here today...> Hi I have been reading for days and I guess I am looking for an answer that doesn't exist!!! <Or at least hasn't been written yet....> We have a 29 gallon that we prepared for weeks ,its water is perfect, the temp is perfect.....My husband surprised me with a 2 inch long horn cow... <As much as I usually approve of surprise gifts, surprise fish are generally not a good thing!> Now I know they have trouble eating for the first few days and they can be stressed easy...At the fish store he was told that the cowfish just came in, so we know he has had a rough few days... <The worst time, IMO, to get one of these fish is right after they have come in. You run a much higher risk of losing the fish if it has not had any time to adjust to tank life. After the first few days, the remaining fish will be the strongest of the ones that shipped. This is why many people will put a "hold" on a fish, even putting a deposit down, while letting the fish stay at the store for a week or two -- to avoid getting a weak individual.> We tried live shrimp and black worms...nothing...Today he is swimming on the very top of the tank almost hissing and spitting at us...Now I read they do this ...but he does it for hours... <Well, cowfish will spit water when they hunt. He's hungry! This is a good sign. They usually eat clams, squid, octopus, fish, and other benthic invertebrates. Do wander over to http://www.cowfishes.com and http://groups.yahoo.com/group/CowfishPuffers_andMore/ for more info! Also when he does go to the bottom. he falls to his side. no energy at all.... <I think I have seen this before... do ask on the Cowfish boards about this behavior.> His coloring is fine and his eyes are all clear!! I realize he is dying but what did we do wrong??? Was he too stressed... <Quite possibly.> Is it good to wait a few days while he gets used to a pet shop tank?? I would think not!!! <See my comments above> If there is anything we can do now or in the future let us know.. ps we have live rock and a tiny damsel that's doing fine....The cow fish is the only one not doing well. The damsel does not bother the cow at all. <At least not yet...damsels do get to be much larger, uglier, and meaner as they get older.> THANK YOU....LESLIE. I tried to research this myself and believe it or not I couldn't find a question (or answer ) just like mine.... <Do consult with the good people on the cowfish board mentioned above. They have a lot of experience with the specialized care these fish require. --Ananda> Liverock, Shaw's cowfish, and a temperate aquarium >Hi Bob, >>Good morning, Sal. Marina is here for you this morning. >I hope you are well. >>I will make an assumption that Bob is, indeed, doing well, and I would say that I'm doing well, as well. I hope you are well as well, too. >I'm interested in keeping a Shaw's cowfish (Aracana aurita). He will be in a 75 gallon tank. This tank will have to be kept cool for this cowfish. Can I keep live rock in this tank for the main filtration device, or would 68 degrees be too cold for it? Should I just use a trickle filter? Thank you very much for your advice. >>Hhmm.. good questions, all of them. Well, 68 would definitely be the low end of the temperature spectrum for *tropical* live rock, that is to say live rock that has been grown and harvested in tropical waters. However, being as how that is so close the 70F range, I'd be quite curious to try it, even just a little bit might yield interesting results. Generally, though, we can say with a fair degree of certainty that it would be ineffective to attempt to utilize that tropical live rock in a "temperate" setting (albeit on the high end of the scale). I would go with a deep sand bed for primary filtration, including denitrification, with copious foam fractionation. To get it well on its way *before* I added the fish I would begin a "fishless" cycle--using shrimp or similar tossed into the tank to create a source for ammonia and so on. I hope this has helped, and best of luck! Marina Copepod Temp. Hi Bob, <Hello Sal (my brother-in-law's
name as well)> I am setting up a cold water tank for Shaw's
Cowfish (Aracana aurita). I'm looking at putting one male, one
female and 3 juvenile in 180 gallon tank. <Neat. A gorgeous
species> The temp in this tank will be 66 degrees. The filtration
will be accomplished using an oversized protein skimmer and wet/dry
filter. As a food source, I plan on breeding copepods. This will be
accomplished in a separate tank at a temp. of 75 degrees. Then I will
transfer them to the main tank. Will these copepods survive at this
cooler temp. for a while? <Yes, they should easily> Do you think
they could breed in there? <If not consumed, possibly> I am
asking these questions because if I plan on vacationing I've got to
worry about feeding them. <Not to worry (much) here. I know this
genus can go for many days w/o feeding (they often do in transit from
collection to their "end-user" site)> Also these fish need
algae. Would you use something like Ogo ( temp. concern ) or just throw
some sea veggies on a clip for them? Sorry about all the questions, but
you have all the answers. <I would try live seaweeds and next dried,
reconstituted seaweeds (Kombu, Nori...) and leave off with terrestrial
greens. Bob Fenner> Gratefully, SAL Boxfish! HI! I fell in love with the Ostracion cubicus and I read that these fish get pretty large...what would be a good tank size for one of these fellers?! <At least eighty gallons> Also can you tell me about the white spotted boxfish, I am debating over what the purchase, both are just so adorable! Thanks - Ash <What's posted on WWM is about all I have. Bob Fenner> Lactoria fornasini Hi All, <Tyler> I just bought a 55 gallon tank to go along with my 135 gallon reef. I have always wanted to keep cowfish. My plan is to keep two thornback cowfish (Lactoria fornasini) in this tank along with live rock and sand (no other fish). I am going to run a AquaC Urchin for a skimmer but am lost after that. Do cowfish require a refugium for filtration or would I be okay with just a sump? I want to get everything straight before I start. Thanks a lot. Tyler <They do need, appreciate good water quality... and this species can become very large... see fishbase.org re... and can indeed be very "messy"... a refugium would be best... a sump at least useful... and they will need larger quarters. Bob Fenner> Lactoria fornasini - Take 2 Thanks for the response. You said that this type of fish gets large, but this is the smallest of the cowfish at 5.9", correct? <No... nine inches maximum... you obviously did not look on fishbase.org...> Scott Michaels book calls for a minimum of 55 gallons for these and they will be the only fish in the tank. Is this still acceptable? <For one...> One more question. Where in the heck can I buy these online? I did a search and didn't come up with much. Thanks for the help. <Please see WWM re... Bob Fenner> Boxfish Hi Bob, <Or Maddox, and he's listening to Yahel... :D> Yesterday, I asked you about putting two thornback cowfish in my soon to be 55 gallon. You didn't think this would be a good idea. <Boxfish grow too large for a 55> In your opinion, what is the best all around boxfish to put in a 55 gallon? Things I would like to keep in mind for this would be availability, hardiness, ability to get along with other tankmates. <No boxfish will be able to remain in a 55 gallon indefinitely (I'm not aware of a boxfish species that attains less than 18"), no boxfish is hardy, though Whitley's boxfish is probably the hardiest out of the genus. Boxfish are best housed alone or with other peaceful tankmates that won't outcompete them for food> Thanks. <You're welcome - M. Maddox> Boxfishes Hi Bob, First of all, thank you in providing a truly "pearl of wisdom" on the net : your website is the answer to almost every aquarist prays; it could use a search engine though ; <Hmm, does have one... the Google search is on...> Anyway, I recently fall in love with two box fishes : Ostracion cubicus Ostracion meleagris <Both cuties> I have a spare 15 gal tank.. I wonder if I can setup it up and house a pair of meleagris and a cubicus in there ? Will these species fight ? <In such a small tank... bad proposition... even for just one specimen... really.> I found info about these fishes contradictory : some authors say they are very difficult to keep, others say easy... What's your opinion ? <Easy enough to maintain in a large, stable setting... about sixty gallons per...> In my 180g reef I think I might have a mantis.. I've found that the Labracinus lineatus ( Australian flame Basslet ) preys on mantis ( or is supposed to ). Is this fish considered reef safe ? <As a juvenile yes... as an adult, can be trouble.> best regards my friend, Goncalo Proenca <Be chatting, Bob Fenner> Fast Growing Boxfish I have had a very healthy boxfish (cubicus) for about 5 months now and he is growing quite fast (about 4 inches long now) and eating more and more as time goes on. I'm wondering if he will be okay indefinitely in my tank or if he might outgrow it: the tank is 125 gallon with quite a bit of live rock. My other concerns are that he will get too big to reach the floor between the rocks in order to feed and that he might get so big as to dominate the tank to the exclusion of other fish. What can you tell me? -Pat <Well, Pat, I can tell you that these guys are pigs, like you mentioned, and will swim around at the top of the tank begging to be fed. Adults approach 18 inches, so your fish is eventually going to get rather large for your tank. Diligent attention to a high quality protein skimmer and changes of activated carbon are in order. You can read further of these fish at http://www.wetwebmedia.com/boxfishes.htm -Steven Pro> Boxfishes, and a new SW aquarium... Mr. Fenner... <Hello> I'm a beginner at this but I believe that I have read just about anything there is to know about caring for a boxfish... I am thinking about putting up a new SW aquarium... I'm a little short on cash for now, so I am going to purchase no where larger than a 30-50g tank... to go with the new set-up... I am thinking about purchasing a boxfish (preferably "Ostracion cubicus" or yellow boxfish)... any suggestions you can make on how I should set-up the tank... live sand or live rocks... <Live rock... which will inoculate the substrate, make it live as well> I know that I should not include reef for it would get picked on by the boxfish... any suggestions on what types of fishes or inverts that are compatible with the boxfish.... <All sorts... please read through WetWebMedia.com re Ostraciids, invertebrates...> I know that the tank is not big enough to accommodate the size of the adult boxfish, but I know that a juvenile will suit it fine... therefore I will purchase a much larger tank to accommodate the fishes' growth... will a porky puffer go well with the boxfish... I know that they wouldn't, but because of my love for both.. are there any suggestions you can make to make it work.... sorry for all the questions... any response will be great... <In a large enough system, these fishes can be kept together... good filtration, skimming is called for... and regular maintenance to maintain good water quality... with such high metabolism, meaty eaters. Bob Fenner> gratefully... Sokha |
