Kole tang ich update and macroalgae Hi Bob Fenner, I wrote several weeks ago, several times, about my Kole tang with ich. Well, he has been in his hospital tank for two weeks, with a gradual reduction of spg to now 1.016 and temp at 82 degrees F. He is doing great! As of yesterday, he had no more ich cysts present on his fins or body. He is healthy and his color is really bright ! I feed him brine shrimp in the morning, and a prepared frozen algae (mostly Spirulina) in the evening, then again at night. He actually comes to beg when he sees me come into the room. (Brine shrimp are his favorite food.) I suppose I will leave him at this spg for another 3 weeks since the main tank will have been fallow for 5 weeks at that time. Is this too long to leave him in this low salinity water? (Total of 3-4 weeks in spg=1.016) <No problem> About the main tank,... I have begun to stock the refugium part of my sump with macroalgae (have only actually purchased 2 different kinds, but as of last count have 6 different kinds present,....) Since I upgraded my lighting down there to 64W power compacts (15 gallon refugium area), things have begun to pop up everywhere. I have one kind of Halimeda which has very large "leaves" and is beginning to cover up a small piece of coral which has just began to extend its polyps for the first time. Both are located on a piece of live rock I purchased back in April, they have just never been under sufficient lighting. I would much rather the coral get to growing, over the Halimeda, but is there any way to pick the algae off the rock without harming it and "replant" it somewhere else in the tank? <Best to make a small "chip" off the rock with the holdfast mechanism of the Halimeda intact on it> Thanks for the constant, consistent advice, The recovering pet hospital, Jana <Thank you for the update on your continuing progress, success. Bob Fenner>

Big Mistake - Ich Bob, I think I may have messed up! I purchased a Kole tang, gave him a fw dip, and put him in quarantine. He was there 12 days, but he was losing color and would not eat and was getting real thin. I figured, 12 days, close enough and I thought adding him to the main tank with all the LR would help. So I fw dipped him again and put him in my main tank (90 gal, 90lbs LR, neon goby, some snails and hermits - amm, nitrite/trate = 0, 82F, 1.023). Well, just my luck (ignorance), he came down with ich. So I put him back in quarantine and will begin copper treatment. I'm afraid that in trying to help, I've unduly stressed this poor fish and have also introduced ich to my main system!!! Arghhhh! <I would have very likely done the same...> Should I raise the temp and lower salinity and let the tank go without fish for a month before putting the tang back in (if he doesn't starve to death in quarantine)?  <Maybe... I would wait, see if the fish develop ich there for now> Can I leave the little neon goby in the tank, or would he serve as a host for the disease?  <Would serve as a host if ich virulent enough... as stated, would wait at this juncture> Thanks in advance for any advice/help you can give. Frustrated. <Steady on my friend. Bob Fenner>

Kole tang update Hi Bob Fenner, Hope everything is going good with you. Things are pretty good in my tank world. Here is what is going on and the questions that I have: I had a Kole tang that developed white "ichy" spots on his fins, no other fish (two little damsels) were affected. You suggested I lower the spg of the tank and raise the temp which I began to do (of course this takes several days). I decided this weekend that there was some maintenance which needed to be done to the overflow box and tank itself (you know, small things you want to fix but can't once everything is in place), and I had the time and lots of extra tanks, so I broke the tank down to go fallow for a month. The Kole (his name is Ole since it rhymes) is in a super long, short and wide 20 gallon hospital tank (he's in the best hospital in town) with a little hang on filter with carbon and extra powerhead; and the other damsels, shrimp, and snails are separated accordingly in various tanks throughout the house. This evening all maintenance will be fixed on the main system and it will be up and running again with live rock, shrimp and snails, but NO FISH, in it. All fish are doing great and seem happy. Ole the Kole is eating like a pig (I am trying to not feed him too much right now since he is in a not too good - filter wise - system), and he even got a fresh water dip for 5 min.s. before he went in the hospital. He did great, even let me pet him for a few minutes while I sat with him. The spg of his tank is at 1.020 right now. He still has some, but not as many white specs on him, and he twitches a little every once in a while and ONLY in the morning - weird huh? <Not weird in the sense of unusual> (I watched him for many hours this weekend) Is there any medicine I can use to rid him of this disease completely?  <Mmm, I would lower the specific gravity to 1.015 if it's just Ole... and leave it at that... no "medicines"> Methylene blue is completely unavailable in CA as far as I know. <Really? Don't think so...> And if he still shows signs of these white specs when my one month fallow period is over, DO NOT put him in the main tank, right?  <Correct> And if he is clear of disease, freshwater dip him before he goes back in the main tank, right?  <Yes> Also, should I boost his immune system with a vitamin supplement?  <Good idea> He eats mostly off of the few pieces of algae covered live rock that are in the tank with him, some frozen algae food which mainly has Spirulina in it (sorry don't remember the name brand, etc.), and live brine shrimp every few days or so. Does he even need a vitamin supplement? (I realize that if I treat him with medication then the carbon and the live rock have to leave the tank. ) <Would help> Thanks for any input you might have on this matter.

Please, no lectures, Dad (Kole tang early introduction) Hi Bob Fenner, In view of our country's latest tragedy, if you are not answering emails, I understand, I don't feel much like working right now either, but I have something that needs to be dealt with immediately. <Am of the habit, practice of trying to do "simple things" when in turmoil...> I bought a Kole tang this weekend, and was concerned about handling him since their mouths are so delicate, so I opted not to quarantine him,... or dip him. Alright. Alright. I know, I have read it all. I know what I should have done, but the fact of the matter is that I just couldn't bring myself to watch him come onto the brink of death while swimming around in freshwater. I just figured that the chances of me hurting him were worse than the chance of him coming home with parasites. So I acclimated him slowly to my tank, and there he is. Here are all the specifics: He first had one white spot that sticks out like a grain of salt on one of his fins, now he has a few more little ones close by the first one. He took to my tank quickly. He eats all of the time, and I really don't even have to supplement him, he usually ignores the food I offer (which the cleaner shrimp gladly eats - Nori) and eats things I can't see, and some things I can, off of the rocks. He is very active, not scratching at all, and loves swimming in the strong current I have flowing through the tank. I also have two damsels in the tank. They are completely unaffected, of course. I have seen the cleaner shrimp jump on the Kole tang and quickly clean him, but this has only happened twice. Most of the time the shrimp just hangs out on the Nori eating, eating, eating. All of my animals, even the ones not in water, beg me constantly. There is no lack of appetite in my house, that's for sure. The tank: 55 gal future reef, 75 lbs. live rock 40 lbs. of sand (very thick sand layer), some macroalgae, no amounts of ammonia, or nitrate, has been running since April, 2 yellow tailed damsels, 1 cleaner shrimp, 1 Kole tang, run Berlin method. Everything is pointed to healthy, but he has the white dots and that's it. Should I just wait and let the cleaner shrimp do his job, or should I break everything down right now and get them all separated and treated? Will the shrimp even do his job if he is eating too much? And if I do have to let the tank go fallow to rid it of these Protozoans, can the shrimp still hang out in there or not? Any advice would be appreciated. Jana <I would likely just leave this fish in place. If it had much of a "going" strength pathogen... your system would/will have it by now.

Re: Update of Kole tang with ick Hello again, I am very sorry about bugging you so much on this one. This is all my fault and I have learned my lesson. You can lecture me all you want now, Dad. I deserve it. <No fight, no blame> The Kole tang has, over the weekend developed so many white spots. At least 8-10. I have the water temp up to 82 and the salinity I am slowly dropping,... is at 1.022 right now. All fish are the same, they all seem completely unaffected. I purchased a Lysmata debelius this weekend, and he is doing good and helping clean the tang. But why is it that when both of my cleaner shrimp jump on and clean, they never pick off those little white crystals on the fish? What are they cleaning? <What they can, want... other materials, necrotic tissue> Things I can't see? And as far as lowering the specific gravity and raising the temp of the tank, that's a quick fix for now, but what about when things go back to normal conditions? Will the tomite stage of the Cryptocaryon life cycle still be present in the tank?  <A question of balance. If your fish livestock are "healthier", the system more favorable to them... then no, the ich/Cryptocaryon will not "achieve" epidemic proportions> If I do have to resort to placing the Kole tang in a hospital tank what water should I use for the hospital tank?  <Initially, the system water... this is detailed on the WWM site.> My infected main tank water or my premix salt water outside in the new garbage can? I realize he needs to be in water similar to his own, but does this include infected water? And I realize I have to dip him as well. Freshwater with adjusted pH and temp equal to that from which he is coming and Methylene blue,....? I have some Rid-Ick from my previous freshwater days which contains formaldehyde and malachite green. Would this be safe to use for him as a dip? And if I do have to let the tank sit fallow for a month or so, can my invertebrates still stay and hang out in there? <Yes> I have read nothing to the effect of them "carrying" or contracting these sort of fish diseases. And during this "fallow" period if the damsels were to be in this tank, yet not display any signs of the Trophont stage on their bodies, would this necessarily mean the Trophont stage of the parasite has died since it only lives for a short time if it doesn't find a host?  <No, only that you might not actually see it... the damsels have to be pulled as well> Or is it just safe to go ahead and take them out as well, and truly let the tank go fallow? Also, could you please suggest a scientific journal article or something similar on Cryptocaryon irritans or such.  <A very good general reference: Noga, Edward J. 1996. Fish Disease, Diagnosis and Treatment. Mosby-Year Book Inc., St. Louis. 367pp. Just met this gentleman at the recent MACNA XIII btw. Very complete work> The internet is very helpful, but I really need to learn more about this things life cycle in order to conquer it. (I have a degree in biology and can understand most writings in this field, so fire away.) In fact, since I started all of this marine tank insanity I am thinking of going to get a Master's in the subject. Why not, I already spend most of my free time studying this as it is! <Ah, perhaps I'll re-do my "pitch" on this holociliate (my extant one pre-dates personal computers... circa 1981 if memory serves> Again, Thank you so much for your ongoing support and advice. I am very pissed at myself for not quarantining this Kole tang, now he will be hurt more than he would have been to begin with. And I hate to see any animal suffer for ANY reason. Jana <Translate your agitation into positive action here... You will understand and get beyond this situation. Bob Fenner>
