Poisoned by too much, too long exposure to copper and metal dyes...

pH adjusted dips/baths can work... w/ or w/o formalin.

 

 

 

Golden Puffer... Ridiculous errors in mistreating, no reading About a month ago I realized that my skimmer was not working properly for about 2 weeks. In that time a parasite developed on my fish. I have a golden puffer, imperator angel, two triggers, <Which species?> a clown, and some orange tangs. <?> I noticed a parasite on the angel and higher nitrites. <... how high?> I did a water change and treated with copper. <What type, amount? Not in the main tank I hope> after about a week the parasites seemed gone but my golden puffer stopped eating all together. <Typical... had you read...> Now it has been a month and still wont eat. He also seems to be running into rocks alot <No such word> almost as if he were blind. I have tried putting food near his mouth and he wont bite. Is it possible he will survive this? or do could he have gotten a parasite that caused blindness and complete loss of appetite? is there anything I can do? should I let him ride it out until he dies? or should I at some point euthanize him? thank you.

copper, use in quarantine, on/w/ puffers... Reading      2/11/12
Hi there, I was treating my quarantine tank with copper. I was reading wwm and there are tons of different doses as far as ppm goes. I have my tank at 0.25ppm. Is that alright or should i bump it up to 1.0ppm?
<... 0.2 to 0.35 free copper (cupric ion, CU++), no matter what source/type of product employed...>
 I do have a spiny box puffer in it. Thanks, Jim
<... I would NOT treat puffers (and quite a few other groups of fishes) thus. See, as in read, search on WWM re. Bob Fenner>

Puffer Fading (5/25/04) Thanks Steve! <My pleasure.> Last night I went to the LFS and got some DI water so I will be using that from now on. <Smart. Do consider buying your own system. You will recoup your investment within a year or so.> My puffer seems to be doing worse however. <:(> The Ich is multiplying, his eyes are cloudy and full of Ich, he refuses to eat and hangs out at the top of the tank mostly. I've asked around and someone recommended a freshwater dip (2 others said not to, that it would add to the stress). What are your thoughts on this? <Well, this sounds like a desperate situation. I fear that the stress of a dip could kill your puffer, but he may be too far gone for anything to help and does not seem likely to survive if you don't do something more, and soon. It is probably worth the risk at this point. Do be sure to match pH and temp to the tank. Adding Methylene blue (Available at many LFS) may help him tolerate the dip better by increasing the oxygen and darkening the water. I should also mention that copper can be hard on puffers. Some people oppose using it with them. Search on "copper, puffers" for info. Your puffer may also perk up if you cut the copper concentration way back and treat with hyposalinity instead. See the articles I referenced previously. I'd also add and antibiotic too, because the cloudy eyes may be due to a secondary bacterial infection. Unfortunately, this may increase your ammonia problem by killing even more biofilter than even the copper is already doing. And formalin will do the same. Frequent water changes will be needed. Desperate times call for desperate measures.> thanks again -a <Hope this helps. If you lose him, don't be too hard on yourself, you're doing everything in your power for him.> 
Puffer Hanging In There (5/26/04)
Again, Steve thanks so much for your continued support and speedy reply. <You're welcome.> To update, the puffer looked worse last night so I gave him the freshwater dip with Methylene blue. We caught him with a container (we didn't want to use a net for fear he would swallow air). <Excellent> Pouring off as much of the container water as we could then poured him into the dip; he didn't looked too stressed out, he was in for 2 minutes or so. Unfortunately, none of the Ich came off (maybe too short a dip, also diluted with saltwater). <Straight freshwater for 5-7 minutes is more effective. This treatment is sometimes repeated daily for a few days.> He seemed more lively, and we also then did a 50% water change. I added a poly filter to further reduce the copper. This morning most of the copper is gone, and I'm not sure whether to continue with this treatment. I bought some antibacterial medication too. Do you recommend continuing at low dosage of copper/Cupramine (0.25) or switching to something else? <Did you read the articles at www.reefkeeping.com? Here's the first one: http://reefkeeping.com/issues/2003-08/sp/index.htm > Someone at the LFS swears by this concoction he gave me called 'smurf juice'- a mixture of Methylene blue <hence, Smurf>, formalin and malachite green (add 1 ml/10 gallons for 3 days straight). <I cannot comment on the dosing because I have no idea of the concentrations, but formalin & malachite green are known to be effective against Ich. Like all therapies, they have a downside. You can read more about them at the link provided.> He said not to administer any other anti-bacterial medications if I use this mixture. <My thought on Antibacterials is if the eye clouding seems to be due to bacterial infection.> I fear I'm doing more harm than good because I keep changing medications, but I'm worried about using the copper because it seems to be making things worse (I had read conflicting WetWebMedia points of view using copper with puffers, but decided to go ahead with the treatment because I was told that it's more effective than formalin). <Yes, it is best to go with a plan and follow it through to completion. Copper is indeed controversial, but your experience of worsening suggests that it was probably doing more harm than good in your case.> I need to pick a medication and stick with it, else he's going to starve to death:{ <Agreed. Use the info in Steven Pro's articles to make a decision. BTW, consider joining the forum at http://wetwebfotos.com/talk/ Lots of great folks there who would be happy to share experiences & offer suggestions. I hope this all helps. Steve Allen>
Puffer Getting Better (6/7/04)
  Hi there fabulous WWM crew/Steve, <Hello. Good to hear from you again.> Just a quick question and follow-up.   The valentini puffer is doing very well and has been Ich-free for almost 2 weeks! <Excellent!> The hyposalinity seems to be working. I will keep him in QT for another 2 weeks, almost he looks like he's getting bored-pacing the tank, etc. The 10 g. must be too small. <Yes, but just think how happy he'll be when he can go back into the main tank disease-free.>   My question is, can I use a pre-seeded filter that have been in my main tank for over a month now in the QT to combat ammonia levels? <Since the tank has been fallow for a month, this should be OK.> The main tank's salinity is 1.023 and the QT's salinity is 1.012 (for now), so I'm afraid the nitrifying bacteria will be instantly killed by the difference in salinity. <Being single-celled, bacteria seem to adjust fairly well, and are able to live at a variety of salinity levels. However, acclimating over a couple of hours might help. Another option instead o the filter is a bag of Bio-Spira Marine if it is available in your area. You can add the remainder to your main as a "booster." thanks as always. <A pleasure. Glad to hear things are going well. Stay patient and all will be well in the end. Steve Allen> -a ps. WetWebFotos. com's message board is great! thanks for tuning me in. <Thanks for taking part.>
Treating Ich (5/29/04)
  Hi Steve, <Hello again>   Good/Bad news about the puffer. Last night I came home and he looked a lot better, and fed him a live clam (after soaking in freshwater for 10 min or so) and he ate part of it! <Good!> The Ich had also receded somewhat. <Also good> I did a 50% water change and added the smurf juice dosage (thanks for the links, I had read through them yesterday or day before I believe)   This morning, he looks ok with the exception of the his skin-it looks like it's flaking off near his belly. I know I should pick a treatment and follow through with it, but again I'm having second thoughts again. Sorry to be such a pest with the questions-I'm definitely learning with this fish! Thanks so much, I really appreciate it -Angela <Glad to help. I hope this works out. The peeling may be from skin damage from the Ich. Keep your water free of ammonia and nitrites. Consider adding Melafix to try to prevent infection. Add a broad-spectrum antibiotic if it looks infected. Be aware that this will also kill your QT's biofilter.>

Puffer... Crypt, med., stkg. mistakes  11/19/07 I have a puffer that is like a mappa...I sent in pictures and y'all gave me a few possibilities. ANYWAY I have it in a new tank around 2 months old and it developed Ich. due to stress ( a cryserus <Chrysurus? The angel?> and grouper issues) I took the grouper out an began treating the tank with Quick cure. <... a huge mistake. You put formalin in a main display?> The tank is a 120 with a doss skimmer and fluidized sand filter. it has live rock <Had> in it with the angel a wrasse and a Huma. The quick cure worked the ick spots have gone away <Uh, no> but the eyes are a bit cloudy and I am noticing that it is breathing a lot more with one side of his gills than the other a very noticeable difference.( like you can see in the gill of one and the other is almost closed) ITs appetite is still the same. I have a little ammonia spike going on in between a .00 an .25 and treating with AmQuel + any suggestions? <Yes...> We love this guy <Again... no, not by my definition of love... IF something is loved, one does their best to look after it for its sake... Not here> he is great and would hate to loose <... lose> him. Thanks Marcus <... you've poisoned your mis-stocked, over-crowded system... Read here: http://wetwebmedia.com/cryptformcures.htm and the linked files above. Bob Fenner>

Re: puffer 11/19/07 I understand that you are one of the leading fish experts in the country but you are assuming a lot of things and you know what assuming does. Where do you get my system is overstocked. I have a fluidized sand filter that is meant for a 300 gallons and very efficient protein skimmer not to mention a 57 watt sterilizer. Again ITs a fish only with Rock in it. I could care less about if its "alive" or not. WITH ONLY 4 fish in it. <... read re these animals natural habitats, size of system requirements... IS psychologically crowded now... Will be physiologically soon> Sorry you are having a bad morning but the reason for all my cluttered typing on the previous email is that due to me not loving my fish I read your website for 3 hours looking for something to help and it was really late for me. P.S. If I wanted a grammer <grammar> lesson I would asked Calfo (the educated one) for help. You do not have permission to publish any of my emails to you. <Live, and hopefully learn. BobF>

Crypt...urgent _ seriously  - 4/24/2006 Good Morning <Still> I have been reading Ich and puffer FAQs for the last 7 hours. I think I have the groundwork covered.  I had a small outbreak about a year or so ago and came out with no losses. That was party a result of very diligent dips etc but a lot of luck too: You've heard this story a thousand times but yeah, <Likely more> I used CopperSafe on the advice of LFS guy and my 2 puffers and 1 trigger made it. And that was in my display   tank - even all of the hermits survived. The live rock is back now. but that took forever. I'll chalk that up to luck. These fish have been there before and after looking at some risk management, they (some our fish are going   on three years old) have decided copper is an unacceptable risk. I would love a response this morning. Here are the details - '¢ 180g + 50g sump. '¢ A few damsels '¢ Small Heniochus pair '¢  S&S Puffer 9" (This is his tank of course) '¢  Tiny dogface puffer '¢  Small flame angel '¢  4" humahuma '¢ 2 small yellow tangs '¢  mediumish snowflake moray '¢  lots of crabs and liverock My wife spotted an Ich outbreak this morning, so at least we have the head start. I'm pretty shocked at how quickly it manifested though;   <Mmm, has been there all this time... just some trigger... not the fish.> this wasn't here on Friday evening. This is the early stage, everyone is behaving normally but I know I need to move quick. Both puffers have light spotting on fins - same for both Henis. Damsels are all clear. The angel and the trigger already have body spots. I bought a good hospital setup after I found out today. 55 gal generic with decent hardware. <... not so sure all these fishes will go/get along here> I have a good understanding of hyposalinity and temp etc. We are pretty good dippers too. I really just want to know what   product to pick up..? <?> I'm thinking no copper,  no malachite green, Methylene blue is a maybe but Formalin at 37% is a good idea. Yes? No? <... Please read here: http://wetwebmedia.com/formalinart.htm and the linked files above...> I need to start this now, advice would be appreciated beyond words.   I'm scared for there guys. <More knowledge will lessen to almost completely diminish your fear> Cheers, Christopher <Bob Fenner>
Re: urgent _ seriously ... Crypt - 04/24/2006
Thank you for your quick reply but  I'm confused I have re-read the formalin page; is this a cautious endorsement? <Perhaps> I guess to distill my question to it's essence: I would like to know specifically which product would be best to start treatment now;   Methylene, formail or something else? Thanks in advance, c. Christopher Roberts <My friend... this is posted over and over on our site... with cautionary remarks as you suggest here. I would not use formalin/formaldehyde... or formail... I would use a minimum concentration (due to the puffers mainly) of a chelated copper commercial product here... with twice daily testing with a matched test kit... Read on first! Bob Fenner>
Re: urgent _ seriously... Crypt  - 04/24/2006
Thank you Bob <Welcome> I appreciate your directness. Do realize that many many WetWeb crew posts here absolutely forbid the use of copper with puffers (in ALL CAPS)- period. <Yes... am fully aware of some others opinions here (have placed almost all materials on WWM... over the last decade)... My opinion, experience varies you might say> But yes, I was aware that you are a proponent of it. <Oh! Good> I am out the door to pick up a good copper test kit in a moment. Please advise a suggested dosage.   1 ppm, monitored 2x daily over a 2 week period? <... no... posted on WWM for all's review though> Many Thanks. *Hopefully I won't write you again until I just drop a brief Thank  You that all my guys are flourishing. Cheers, c. <Write away. Just do please search and read first. Bob Fenner>

Puffer with wound that has bugs crawling on it  - 2/21/2006 Hello, I have a dog face puff that got hurt by a powerhead last week, I have been treating him with MelaFix and PimaFix <Worthless> and seems to be healing. I have 2 questions first there are these tiny white bugs on my glass and sand and I have noticed them on the wound area on my puffer, are they hurting my fish or will they just eat off the dead skin that is falling off. <Likely not helpful> 2. I haven't seen my puff eat but a little bite of shrimp the other day, but he continues to poop it is white and falls apart as soon as it leaves his body. If I'm not seeing him eat how is he still having anything to poop out. I just don't know if he might have a digestive  or secondary infection. This is my first puffer and not sure if this is normal. I do have a sand bed in the tank but it isn't sand that he is getting rid of. Thanks for you time. <Please take a read, re-read over the Puffer materials archived on WWM. Bob Fenner>

Dipping a sick puffer Hi, thank you for telling me. My porcupine puffer has Ich and was wondering how long should you keep him in the bath for and also how often should I do it. I am also going to go buy some medicine for him. <Please read here: http://wetwebmedia.com/dips_baths.htm and: http://wetwebmedia.com/pufferdisfaqs.htm and the Related FAQs files (linked, in blue, at top). Bob Fenner>

Copper + Puffer = Problem! Help!! We've had our porcupine puffer for a year and in last 2 months developed white spots which then started peeling off.  Our aquarium service guy added copper and does partial water changes every 5 weeks.  The dark colored skin is totally peeling off to reveal white skin underneath.  We just removed a trigger fish who was pecking at the dead skin.  Ever heard of this??? <It is most likely a "side effect" of the copper. I would avoid using copper for puffers; instead, formalin-based remedies are safer for maladies like Cryptocaryon. Copper, although quite effective and safe in many instances (when used correctly, of course), can have negative consequences for some species of fishes, such as puffers and Centropyge Angelfishes (as well as tangs, if exposed long term). Do exercise care with it's use. Copper really should not be added to the display under any circumstances, IMO, as it is difficult to control the dosage, not to mention the possible side effects on invertebrates and other animals. It needs to be administered in a dedicated treatment tank devoid of substrate, and its dosage carefully monitored with a test kit. You can help remove some of the copper in this tank by utilizing PolyFilter or Cuprisorb, which both excel at removing copper from saltwater. With use of one of these media, as well as regular water changes (and overall good husbandry techniques!), you should be able to nurse this fish back to health. Good luck! Regards, Scott F>

Sick porcupine puffer (11/22/03) <Hi! Ananda here tonight> My fish Hope, having a few months ago survived a serious Ich break resulting in the death of all other fish (I finally gave in to trying copper after all else failed) now looks sick again...but in a different way. He is breathing hard, has lost much of his color...And almost looks as if he was pricked by pins in certain areas. Some of his fins are torn...Any ideas would be greatly appreciated! <Could you let me know what your ammonia, nitrite, and nitrate levels are? And also the tank pH and temperature? That will help rule some things out. I'm also wondering how much water circulation you have. And if you could get a photo, that would help, too. I'm not quite sure what you mean when you say he looks like he was pin-pricked -- small holes in the outermost layer of the skin, or small spots of blood on the skin, or...? Get some water ready for a water change and email me back with some test results, ok?> Happy Thanksgiving !  Bonnie <Thanks -- Ananda>

Copper and puffers (07/26/03) <Hi! Ananda here tonight...> 1. Had beautiful gold spotted puffer in tank with serious ich outbreak.  LFS said treat with copper power in show tank.  NOW know that was a bad idea. <I would never treat anything in a show tank...> Conscientious Marine Aquarist suggested puffer fish OK with copper Ananda said get out of copper and do daily water changes in QT tank Which is right????? <To some degree, both. I always try to steer people away from using copper with puffers and other scaleless fish because they are *so* touchy with copper. While it is *possible* to treat puffers with copper, it is also *difficult* to maintain the copper at a level which is sufficient to kill the parasites without endangering the puffer. (As an example, a couple of days ago, one reader lost a puffer moments after putting it into a coppered tank. The tank had been used to treat an angel, which survived the same level of copper that was lethal for the puffer.) Add to that the fact that copper will also kill all beneficial bacteria in a setup, and that means the hospital tank is likely to have some ammonia -- which is deadly to any fish. The combination could easily prove too much for a puffer to take. Freshwater dips are significantly less dangerous to the puffers (as long as you keep their heads submerged so they can't gulp air!). And the daily water changes are designed to do accomplish two things: keeping the ammonia levels down and removing any ich from the bottom of the tank.> 2.Also, tank had constant bubbles from Iwaki 55rlt pump with wrong sump ( too small) and couldn't keep up with water flow and was sucking air too.  Is this a source of stress for fish? <It could be.  --Ananda> Thanks, Russ

Porcupine puffer not doing well (03/18/03) Hi, <Hi. Ananda here this morning...> I would really appreciate some advice about my porcupine puffer fish. Fist of all this is my set up 28 gallon tank <Gah! Way too small for an adult porcupine puffer. Put a zero on the end of that number and you're looking at a better tank size for these fish.> 1 x Fluval 304 filter GF with 2 x power heads <I am not a fan of either canister filters or undergravel filters on a marine tank. There are better options. More here: http://www.wetwebmedia.com/marineSetUp.htm> stock 1 clown 2 damsels <For a 28 gallon tank, those three fish are enough. With two damsels, possibly more than enough.> 1 snowflake eel 1 poorly porcupine puffer <see size comment above> AM = 0 NI = 0 NA = 20 PH = 8.4 <These readings are pretty good.> tank is 4 months old <I'm concerned that you have added too many fish too quickly.> The puffer has taken a bit of a turn over the past couple of days, to start off he got a coating over his fins of brown stuff, then next day the skin on the back of his neck has started to peel of revealing white skin underneath, in general his colour is not as strong either. <This does not sound good. I would put this fish into a hospital tank immediately. I am not sure what this is, so will forward this back into the queue for others' comment(s).> Now his eyes are not as vibrant or puffer out but glazed, and has stopped eating, I have spoken to someone on the phone at the shop and have said its a bacterial infection, and that I should treat it with something called myxcel *Spelling. <I'm not familiar with that one.><<Me neither, maybe an antibiotic from the spelling... would not use this here... likely as you hint the root problem is environmental. Possibly just low dissolved oxygen.>> Do you know of this to happen to a puffer? what causes it? how can it be prevented? is my fish going to live and look as good as he once did? is he going to live? <I'll hold off on answering these, as I don't know what the disease/problem is, precisely.> I'm desperately seeking advice as I'm very upset as I love the puffer <The porcupine puffer is my favorite fish, but I don't have one...I'm waiting until I can get a nice big tank (I'm holding out for a 240 gallon). It'll be a few years yet. Until then, I will continue to enjoy them from a distance. You might need to do the same.> Thanks Ryan <You're welcome. --Ananda><<Bob F.>>
Porcupine puffer doing poorly (03/19/03)
Hi Ananda, Thanks for your quick reply, <You're welcome. Hopefully more of my brain cells are functional at this time of day.> I don't have a hospital tank to put the puffer into, and definitely cannot afford the expense of a whole new tank and filter system. what can i do? <You don't need to use an actual glass tank for this -- a Rubbermaid-type container would work as well in this case. For filtration, an air-driven sponge filter would suffice. You NEED to put this fish in a hospital tank before it infects the other fish in your tank. I found out that the symptoms you mentioned are indications of an Oodinium pillularis infection -- aka marine velvet. More info here: http://www.wetwebmedia.com/velvetfaqs.htm and http://www.wetwebmedia.com/velvetfaqs2.htm > I've spoken to the local shop and he said to use myxinal in the tank, an non-copper based treatment which is not harmful to the other fish. <Must be new and/or UK-based...I couldn't find any mention of this via either a Google search or a Dog pile search.> thanks Ryan <Hope this helps.... --Ananda>

Puffers and copper, take 2 (07/26/03) <Hi! Ananda here tonight...> I knew that scales fish do not tolerate copper well from experience treating my Sweetlips and powder blue tang. I was reading your website and it said copper is a good treatment for puffers maybe its a typo but this is under the disease section of puffers. "Puffer species are very susceptible to Cryptocaryon and Amyloodinium (as well as the eye, skin abrasion, and gas from lifting maladies already mentioned), but fortunately respond well to copper treatments." <Hmmm. My response to another person who mentioned this recently: 'I always try to steer people away from using copper with puffers and other scaleless fish because they are *so* touchy with copper. While it is *possible* to treat puffers with copper, it is also *difficult* to maintain the copper at a level which is sufficient to kill the parasites without endangering the puffer. ... Add to that the fact that copper will also kill all beneficial bacteria in a setup, and that means the hospital tank is likely to have some ammonia -- which is deadly to any fish. The combination could easily prove too much for a puffer to take. Freshwater dips are significantly less dangerous to the puffers (as long as you keep their heads submerged so they can't gulp air!). And the daily water changes are designed to do accomplish two things: keeping the ammonia levels down and removing any Ich from the bottom of the tank.' I've just read too many stories of scaleless fish doing badly with copper treatments to recommend that people treat Ich with copper, when it is possible to treat it with freshwater dips, hyposalinity, and water changes. --Ananda>
Puffers and copper (07.25/03)
<Hi! Ananda here this afternoon...> I am sad to report that my puffer passed away. <Sorry to hear that.> I noticed that he started to develop ick. I had a quarantine tank setup already because I received a Angel that had been shipped to me with ick. The tank was medicated with copper so I placed the puffer in the tank. <Oh, no... never, never put puffers in a tank with copper. Copper is very dangerous to scaleless fish, as it will pass into the fish's system much more quickly than it would for a scaled fish.> After about 2 minutes the puffer started to go crazy spinning in a circle and trying to jump out of the tank I didn't know what to do I couldn't place him in my main tank since he had ick and he seemed to be suffering in the quarantine tank. <Back into the main tank would have been good, despite the Ich. Ich can be treated by other means besides copper (hyposalinity, freshwater dips).> Wasn't sure why he went crazy in the quarantine tank I keep all the stats the same in both my tanks so its a better transition when I move the medicated fish to the main tank. <Yes, that is a good idea... it's just that the puffers can not tolerate copper. Sadly, you are not the first person to make this mistake. Bob, Jason -- could we put a banner or something on every puffer page on the web site that says "Do not use copper with puffers!" or some such? And have it be a link to a short text as to the reasons why? This sort of story is far, far too common, and frequently fish store clerks ignorantly recommend copper to people with puffers. --Ananda>

Crowded hospital tank? (06/19/03) <Hi! Ananda here this afternoon...> I have a cycled 20g tank that I am moving my pufferfish into to treat for what I suspect to be some sort of parasite.  It is cycled, but I don't know if it can handle the increased bioload of the 4-5" fish (previously just temporarily housed feeder shrimp).   <Probably not. You're going to need to do *daily* water changes.> I have been running back and forth for 5 gallon jugs of RO water, can I just mix up about 50g of tapwater instead?  I would treat the water with Amquel (municipal water) and then mix and aerate for a day.   <Sounds good.> Until I get an "OK", I am just going to keep running.  I will be using chelated copper sulfate (CopperSafe) to treat the parasite, its the only copper I could find. Ryan A. <Ack! No copper in a tank with puffers or other scaleless fishes! You don't give any details on what parasite you think it is, or we might be able to give you some direction on what to use. If it's an external parasite, start out with a freshwater dip.... --Ananda>
Copper and scaleless fish? (06/19/03)
<Hi! Ananda here again...> Things have rapidly moved forward, my main concern was with whether or not the treated water would be fine for my purposes.  I got the info not to use copper, which is a bit unsettling because Bob mentions how well in works on puffers in his TCMA book.   <Puffers and scaleless fish can easily be harmed by an overdose of copper. With the CORRECT dosage, copper is okay -- but it is VERY easy to overdose! Further, copper tests may not always be accurate, and many hobbyists are not willing to test for copper twice a day, every day, for as long as they use it. So the usual recommendation about copper and scaleless fish is to avoid it completely -- there are other methods that usually work.> I have since switched immediately to Formalin to treat what is an external parasite.  Thanks for your help! Ryan A.
<You're quite welcome. --Ananda>

Puffers and copper Hello, enjoy you website! Reading the article: /The Conscientious Marine Aquarist All My Puffers, Tobies, Box, Porcupine, Cowfishes It states that puffers respond well to copper, yet in the forums it is repeatedly mentioned to NEVER treat a puffer with copper. Which is accurate? Thx, Patty <Mmm, a bit tricky here... IMO/E Tetradontiforms, including puffers do "respond well to copper"... but a necessary cautionary note here. In general, copper compounds have a narrow range of efficacy. That is, there is not much "room" between effective dosage/treatment and overdosing catastrophe... this range is even smaller/shorter with them as a group... Requiring treatment in substrate-less settings, with "new" seawater, vigilance in testing for and re-applying therapeutic copper (chelated is better here)... and a close eye on accumulating metabolites (e.g. ammonia) and ready change water to dilute same. Other WWM Crew (Ananda, likely Jeni/Pufferpunk) are against the use of copper with these fishes, preferring other chemical use... Ideally, prevention, careful dipping/bath and quarantine procedures prevail in warding off infestations... Bob Fenner>

Porcupine puffer with Ich and eye problems <Hello! Ananda here this afternoon.> Hello, My Porcupine Puffer "Yoda" has been very sick for the past couple of weeks He has all the symptoms of Ich...When I started to treat him in a new 10 gallon hospital tank "PH- 8.1 NH3- 0  SG- 1.023 " with quick cure his eyes started to fog up at first I thought It was just stress but they have continued to Fog... <Are you using the Quick Cure at full strength? That may be aggravating the problem -- puffs and other scaleless fish should be given their meds at half strength, for double the length of time. Also, do you know what your nitrites and nitrates are? Cloudy eyes are usually indicative of poor water quality.> now it looks as if he is totally blind with a thin layer of skin covering his eyes...He also wont eat 3 days now.. <Probably due to stress. These puffs will occasionally go for a week or longer without food. Try feeding him freeze-dried krill soaked in garlic oil (from the "soft gel" garlic supplements at the drug store -- the dried/dehydrated krill will soak up the garlic oil quite well).> I added carbon to the filter yesterday and did a small water change to remove medication from the water I was going to start treating him with Mela fix today <What kind of filtration have you been using in this tank? Melafix won't hurt, but I'm not certain it will help, either.> Have you seen these problems or can you recommend additional/different treatments? <Yes to both... do read up more on saltwater Ich on various pages of the WWM site (use our Google search tool and look for "Ich" and "porcupine").... let me know how it goes with the krill... --Ananda> Thanks for your help, Brian

Ich? on Yellow Boxfish <Hello! Ananda here tonight> We have had our boxfish in our tank for about a month.  He has been very healthy with no signs of disease until today when we noticed about 30 or more white dots all over his body.  We suspect Ich, but the dots do not seem to be clustered around his fins....yet?  He is still eating, breathing and swimming as usual.   <Those are good signs.> We know not to treat him with copper since he is a scaleless fish, and we know he secretes a toxin, which could kill everything in our tank, when he becomes stressed.   <Yup.> Our concern is will he release this toxin if we try to remove him from the tank to do freshwater dips?  Should we do freshwater dips?   <Yes, it's possible that your cowfish might release toxins if the freshwater dip stresses it sufficiently. You can minimize the stress of a freshwater dip by ensuring that the dip temperature and pH exactly match that of the display tank, and by aerating the dip tank. However, some people prefer to save freshwater dips as a last resort for these fish.> Is there any other way to treat this fish?  We have already started to raise the temperature to 80 degrees and are starting to lower the salinity as well.   <You've already started on the primary treatment: lower salinity and higher temperatures. These would be best carried out in a bare-bottomed hospital tank, along with daily water changes, siphoning from the bottom of the tank to get the greatest number of Ich cysts. I've read that people with cowfish are more likely to use UV sterilizers -- which are good only against the free-swimming stage of the parasite, mind you -- to help combat Ich. Another favorite of the crew on the Cowfish, Puffers, & More discussion group seems to be StopParasite. I have no experience with that particular product, so I suggest you check the Cowfish etc. discussion group for peoples' opinions: http://groups.yahoo.com/group/CowfishPuffers_andMore/ > Is it possible that this is something other than Ich?  His tankmates are a Foxface, a damsel, a Kole tang and a couple of snails.  Thanks for any advice you can give. <More on Boxfishes here: http://www.wetwebmedia.com/boxfshfaqs.htm ... --Ananda>

Puffer Problem I've been treating my Porc. puffers for Ich using hyposalinity, and while its suppressed the Ich, it hasn't gone away yet. They seemed okay until this afternoon, when I noticed one of the puffers looks like he has a bruised side. He looks miserable and I don't know what it is. Is it possible that the Ich has caused blood vessels to burst under the skin, or is this possibly unrelated and just really bad timing? <Most likely, an unrelated (but poorly timed) problem> He also doesn't seem to want to move the fin on that side very much. Right now, I'm thinking of starting copper treatments with CopperSafe in a hospital tank because I'm sick of messing around with hyposalinity and it not working (there is a good chance I just don't have the salinity low enough, but now I don't want to wait to try to keep adjusting). But I'm worried the copper will be bad if he's in a weakened state. Please, any advice would be appreciated. <Well, I'm not a big fan of hyposalinity...Lots of hobbyists use this technique to combat Ich and parasitic illnesses, but it seems to be better at preventing Ich than curing it. I believe that medication does a better job. If not copper, then you may want to use a commercial cure containing Formalin..> If he is injured somehow else, I don't know how. He's in with another porky, a Hawkfish, and a ruby headed parrot wrasse. The tanks primary filtration is a canister filter, and the intake is covered. There are rocks, etc... in the tank, but nothing with small holes he could have gotten stuck on. <Hard to say what the cause might be...Could possibly be a trauma of some sort...But I don't believe that it's a disease at this point...> You can also see more pictures of the bruise here: http://wetfish.terminus13.com/misc/puffertrouble/trouble.html <Good pics, but I couldn't get a good feel for what it was...My advice: cure the Ich with a reliable medication (in a separate treatment tank), and continue observations and effort to maintain good water conditions...I think that getting rid of the Ich is he most important thing to deal with at this time....Hang in there! Regards, Scott F>

Puffers with Cloudy Eyes <Hi! Ananda here tonight...> I have a 75 gallon tank with two porcupine puffers two lions and one dog face puffer. I have been keeping copper in the tank to treat and prevent Ich......at least one month...... <I am not a fan of keeping puffers in a tank with copper for so long...> Today both porcupine puffers developed cloudy eyes... worsening as the day went on..... <That is most often caused by poor water quality.> I did a water change about 1/3 of tank....removed all copper....now reads  "0".  ph at 8.2....ammonia at 0.25...nitrites .25 and nitrates 0... <Yup. Please continue with daily water changes until the ammonia and nitrites are at zero. This should help clear up the cloudiness in the eyes.> We love makayla and molly and don't know what to do next.....when doing a freshwater dip, please explain exactly how to do that... tap water with chem.s. removed then what???.... <You need to adjust the pH of the water to the pH of the tank... do see Bob's entertaining treatise on freshwater dips here: http://www.wetwebmedia.com/dips_baths.htm ... Also, when dipping puffers, make sure you keep their noses underwater so they don't gulp & puff with air.> Should I try this?? <If you can still see Ich spots, yes. If not, no.> Will they loose their sight and if so how will they eat.... <Improving their water quality should improve their vision. If not, they should be able to hunt by smell. But concentrate on improving their water quality and they should be okay.> The one did not eat today the other did.... <Not unusual for these fish when stressed.> Please respond ASAP... how often is it safe to do water changes???? <Daily or even twice daily, if necessary to remove ammonia and nitrite.> dog face and lions are showing no signs at this time.......thanks....Carolyn <Work on improving the water quality, and keep the copper out of the tank. Best of luck... --Ananda>

Puffer Problem Hi -- I stumbled across your site looking for information about my golden Tonga puffer, Ralph.   <Hello, Sabrina with you today, hoping to help you and Ralph> I need some help with his breathing--I've had him a month short of two years and have treated him for gill flukes at least twice with Paragon with good success.  This time he's not responding at all, I've done four rounds and sometimes he will move it a bit but never really open it at all.   <By 'it' you mean his gills, right?  Well, gill flukes usually cause fish to gasp and have rather labored breathing due to the parasites causing damage to their gills, so the fish can't absorb oxygen from the water as well.  So far, this doesn't sound like flukes to me.> He's about ten inches long, six around and is in a fish only tank of 80 gallons with a pair of fire clowns, a squirrel fish and a coral beauty.  I'm running two emperor 400 hang on filters with activated carbon and a remora protein skimmer in addition there are two air pumps in his tank and I do at least a ten percent water change weekly.   <Sounds good, perhaps increase the amount of water that you change weekly, and be sure to check your water parameters, make sure everything checks out okay.  You're also going to want to consider going larger in tank size soon....> What would you suggest I do next for him?  He's just not a happy puffer--he no longer wiggles and splashes when I come home but is still eating his shrimp like a pig and some algae but not as much.  Any advice or suggestions would be greatly appreciated, he's my big yellow baby and I'm just desperate to maximize his life span.  When I travel I even have my family come over just to talk to him, he likes company!  Thanks so much, Janine <It may very well be that the very active squirrelfish is stressing your puffer out, and may be that your puff's just pouting about it, trying to let you know.  Keep us updated - hope Ralph perks up for ya!>
Puffer Follow-up
Thanks Sabrina, I appreciate your help.   <Sure thing, Janine.> He is perking up a bit.   <Glad to hear that!!> I've discovered if I make him "bite" at his food through the glass he'll cough and that forces that gill open---so I've been doing respiratory therapy with him and doing that 2-3 times a day <Honestly, I'm not sure if this will accomplish anything - but it'll certainly give him something to be excited about, and perhaps get him out of his sulkiness!> ... and doing more water changes is probably a good idea too.   <Yup, water changes are always good ;)> I've chucked in some Maracyn today just in case it is flukes but I'm with you, I don't think that's it.    <At this point, I'd like to mention that it's always best to medicate in a hospital tank, if you absolutely must medicate.  Many meds will really wreak havoc on your bacteria bed, which will result in ammonia problems, etc., etc. - and especially since we don't know what's ailing your puff (if anything), it'd probably be easier on him to skip the meds for now.> I'm leaning more towards some sort of obstruction and am considering having my vet x-ray him except he won't know what he's looking at once he develops it--- <Yeah, it seems to me that most vets really aren't terribly knowledgeable about fish.  I've seen unbelievably crowded fish tanks at vets' offices before, with incompatible species, even.  But I got to have somewhere for my cat to go when she's sick!> I'll keep you posted and thanks again for the help--I'm not sure the squirrel bothers him, it's more likely the female clownfish upsets him.  She darts at him when he gets too close to the clamshell she considers her "anemone"-- Janine <It could very well be the clown, then.  I know *I* wouldn't want to get in a fight with an aggressive female clown!  Do keep an eye on your fishes' behavior, as your puff's sulkiness may very well be from compatibility issues.>

Puffer eyes Hi, <cheers> I hope you can help me <me too> with a treatment for my puffer fish.  He has cataracts and is blind in one eye and partially blind in the other.   <hmmm... what species of puffer, when did the symptoms set in, how long, any other fishes in the tank, size of all fishes, water quality parameters (specifically measured). More information please> I have treated him with Maracyn 2 and it hasn't helped.   <it is a weak drug (a synthetic tetracycline) and you may not need an antibiotic. In fact, cloudy eyes are rarely bacterially mediated. Often water quality, stress or physical trauma> Can you recommend another medication to cure this.  It is heartbreaking watching him bang into everything. Thank you for the help, Leanne <please advise us of the age of the fish too. Do nothing in the meantime... it is unlikely to be contagious if even pathogenic at all. Anthony>

Re: Puffers on FAQ Hi, <Hello Laura> I was just doing my daily (well, since I started reworking our tank) reading of the FAQ and came across the question on puffers.  These little guys are my favorite fish, and I have kept both species of green spotted, figure eights, freshwater dwarfs, Canthigaster valentini, C. jactator, and C. solandri (have avoided the larger dog-faced and spiny marine puffs due to tank size).  I was hoping you could forward this message on to Tyler Re: what species of puffer to keep in a 20 tall and ordering puffers online. For a 20H, you could keep 1-2 figure eights (sg 1.005), 1 green spotted (sg 1.010-1.015), or 1-2 male and 3-5 female dwarf puffers (freshwater).  Dwarfs are notorious for coming in starving or with severe internal parasites (breeding them would be a noble goal considering how many are lost in the import process). <Agreed> I've seen three batches from three different sources (two different LFSs and another group ordered online for a total of 18 fish) drop like flies even with heavy feeding of vitamin-soaked, meaty frozen and live foods (these guys just won't eat dried foods, not even krill like the larger species).  They also really need lots of live plants to hide from each other when things get sticky.  Sexing can be accomplished as cited in other sources: males are not as round and have a dark brown dorsal stripe and yellow bellies.  For a first time puffer owner, I would really not recommend them because they tend to be very delicate. <Yes... need to be quarantined for weeks, fed foods laced with anti-Protozoals, Anthelminthics... like Metronidazole/Flagyl, Piperazine, Praziquantel... to eliminate internal parasites.>   As far as ordering puffers online, I wouldn't worry about fig eights and green spotteds if your source is keeping them in brackish but I absolutely would not order dwarfs online. These are fish you really need to see in person before you buy, and even then buying them is a fairly big gamble.  I finally got some successful ones that had been started by someone else for a few months; your best bet is probably to find another hobbyist who has been keeping them long-term. Anyways, I'm sure you guys already know all of this and just don't have time to make such an in-depth reply to every single person who e-mails you, so I hope me typing it all out will help :). <Thank you for the excellent input. You will have aided many, and saved many fishes thereby. Bob Fenner> Thanks, Laura

Puffer Treatment I took your advice and got a separate tank.  The puffer is now in it with copper sulphate.  My worry is that he is recovering from a wound and since he has been in the tank with the copper the whitish area is now turning red.  Should I be alarmed? <Do keep a careful eye on this fish. Make sure that the copper is maintained at a proper therapeutic level. If the fish shows obvious signs of discomfort, or if the wound looks worse, you may need to reduce the copper level until the wound heals. Keep very high water quality and make sure that the fish is eating well. Good luck!  Regards, Scott F.>

Sick puffer help Hello,  <<and hello to you.>> I hope you can help me.  <<I hope so too... ;-) >> I have a golden puffer that seems to have come down with Ich. The only noticeable spots are on the fins. I don't seem to see any on the eyes or body. My puffer is scratching a little, seems irritated and hangs out in front of the powerhead. I have a liverock tank with a cleanup crew and the one puffer. I lowered the salinity to 1016 and raised the temp to 82. I hear these fish are hard to medicate and someone told me to use no-Ich or Maracyn and that I could put it in my main tank. I'm a little skeptical and decided to write the experts. Will a fresh water dip cure without medicine? <<It won't 'cure' exactly, but it will pop/kill a good number of the parasites that are bothering your fish. Best to dip for at least five minutes, and up to 10 or 15 if the fish isn't particularly distressed by the dip.>>  I'd really rather not set up a hospital tank. <<You may need to if dips don't have any effect.>>  I do have a 30 gallon I use for this. But it is not set up and has no biological filter. How do you keep the ammonia down while medicating. <<Daily, large [25-50%] water changes, smaller food portions.>>   I know so many questions. I hope dipping will suffice. I also heard to use a low dose of copper, but what about puffers being scaleless?  <<It just irritates them, it's not really 'that' bad... >> I love this fish. Her name is Daisy, she is eating well, but spends most of her time in front of the power head now.  <<Eating well is a good thing.>>  Hope you can help. I appreciate you. Liz <<Cheers, J -- >>
Re: sick puffer help
<<JasonC here...>> THANK YOU. I assume with the fresh water dip that I put baking soda in a bag of water and measure the PH so that it is about 8, what is in my tank, then float the bag to equalize temps.  <<That works, sure... is your tank pH really 8 - as in 8.0? You might also want to work on this and get it more into the marine range of 8.2-8.4>> Put the water in the bucket and the puffer in the bucket. How long, 5-7 minutes depending on signs of stress? <<No less than five minutes - shoot for 10 if you can... I would guess that you will be stressing more than the fish, puffers especially can do 10-15 but 10 should be fine. Good luck. Cheers, J -- >>

Help with Dogface Puffer Hi Bob, Leslie here.  <Hi Leslie, Craig here> You helped me a while back with a tank that had unsuccessfully gone through treatment for Amyloodinium infestations on 3 successive occasions. I asked about microwaving the contents of the tank, my Dad's suggestion... since I had tried everything else I could think of to kill the darn bug. <I can relate to the desperation!> Anyway...... I have had my Dogface Puffer for about 6 weeks. He is a real looker. Pitch Black with clear black speckled fins and a white caudal fin with black speckles. Several weeks ago he developed some of what I believe to be Ich spots on his pectoral and dorsal fins. I saw him flash a couple of times, nothing continuous. He developed an occasional spot on his body which have disappeared. This is a FO tank 50g. I know small for him, but he is only 4" at this time. I have plans for a bigger tank. The thought of investing in a huge tank for this fish, after all those tank crashes didn't seem to sensible. I figured I will get the BIG tank if I can keep him alive long enough to need one. I hope not a stupid mistake. At the suggestion of a highly respected published friend in the marine community I have been using something called OST....osmotic shock therapy. Are you familiar with this? If so what are your feelings about using it prophylactically in a Q tank as well as to treat parasites?  <Lowered SG in conjunction with copper and temp raised to 83F in a QT is the preferred treatment. This is fine if done over time....days.> The recommended specific gravity for FO tanks is 1.010. for 3 to 4 weeks. So I had this guy at that specific gravity for about 3 weeks, when I slowly slowly increased the specific gravity to 1.018 the spots began to appear. He otherwise looks and acts very healthy. The spots have been quite stubborn. I panicked at first because the Amyloodinium outbreaks started like this. I have since increased the temp of the tank....slowly to 80 to 81 degrees, fed garlic laced food and treated the tank with a product called Stop Parasites. The spots look about the same. One of the spots on the pectoral fin is a bit bigger, perhaps looking like 4 or 5 coalescing spots, but not as bright as the other spots. On that fin there is a tiny area at the fin tip directly in line with the bigger spot, that looks like it is worn away, just a very small area. I placed a 15w UV unit with a 90gph flow rate on the tank 3 days ago and FW dipped him last night for 15 min. He did very well......not even phased by it. They look a bit better today. Is it possible this is not Ich or perhaps something in conjunction with Ich? What else would you recommend I do for him. Thank you so much for your help :) Leslie <Yes, remove to quarantine tank and treat with copper @0.25 ppm free copper as above. For more on this go to WetWebMedia.com and enter "copper" into the Google search. I wouldn't advise any of the stop parasite type treatments. Craig>

Sick puffer Hello <Howdy> I have a 100 gallon tank which I use 50 lbs of LR and 2 emperor 400s for filtration. I keep a 12" A. meleagris puffer and a 8" Lunare Wrasse only. Ammonia and nitrite are at 0. Yesterday I noticed the puffer had slightly cloudy eye and was hanging out at the filter outpours. I performed a 30% water change. Today I woke up and the puffer has full blown Velvet ( Lethargic behavior, dashes around a bit, cloudy eyes, and slimy skin. <Mmm... stress-related to some degree...> I have read through your web page and book and will try this: Treat tank with citrated copper and put antibiotics in the fish's food. <And maybe environmental manipulation... oh, see you mention this below> I was wondering if the following would also be useful : FW dips, lowering the Specific Gravity, or adjusting the temperature, feeding garlic. Also could you help me come up with a better treatment plan. right now I'm going to get the copper and a CU test kit and will treat the 100g tank. <I'd skip the dipping... unless this was being done enroute to moving the specimen to another/treatment system... but do the temperature raising, spg lowering... This may all take a while... a few weeks... to effect a cure... and your puffer will likely go on a feeding strike... not to worry much re the latter. And... I might try/risk a cleaning symbiont... likely a Gobiosoma/neon goby species. Bob Fenner> Thanks in advance, Everett.
Re: sick puffer
Thanks for the prompt reply I guess I should not have done quite so large a water change in hindsight. I have applied copper to the water and the test kit shows it to be at .10 parts per million. What would you recommend I lower the sg to.  <To about 1.017... no more than a thousandth per day> It is at 1.023 right now. What about temperature?  <Mmm, please read through the marine disease sections of our principal site... perhaps starting here: http://www.wetwebmedia.com/parasiti.htm on to the many FAQs pages.> Its normally around 77. I will try to find a cleaning goby as well. Again, thanks for the advice and I hope he pulls through. <With your careful work, they will. Bob Fenner>
