Dipping a hippo!  11/21/09
I ordered a hippo tang from Liveaquaria. It is supposed to be here today. I had to put some aggressive fish in the quarantine tank. I don't want to add the hippo because of aggression. Should I freshwater dip the hippo before adding him?
<Yes, I would. Bob Fenner>

Hippo tang vs. the net 11/11/09
Hi,
Two days ago I moved my Hippo tang to QT to treat him for ich.
The net got caught on his spikes by his tail and I had to cut the net to get him free.
<Good move>
In the meantime, one side of his tail is very red and I'm afraid of infection.
My questions are:
Should I treat this with an antibiotic and can an antibiotic and copper be administered at the same time.
<I would not>
There is still a small piece of netting stuck to his tail. Should I try to get that off now or let him relax before I stress him out again.
Thank you
Anne
<I have seen this sort of trouble with many fishes over the years, particularly Tangs/Surgeonfishes. I would leave the bit of net on the fish for now... it will rot off in time. The redness too will cure of its own, with time, good care, general stable circumstances. Bob Fenner>

Hippo tang still sick? 11/10/09
Hi Bob,
<Reuben... on rye a fave>
After taking your advice and putting my yellow tang into a colander for a few days and putting my hippo back in the tank not a lot changed, he did start to eat a bit of food if I put it near his mouth, so after 5 days I decided that I didn't want to leave the yellow tang in the colander so put him back in the tank but put a panel in to separate the tank in two.
<Okay>
It's now been nearly 3 weeks since I put the hippo back and although he has been eating a bit of food if it is put near him he still hasn't started to swim about the most I've seem him do is swim up a little go White and then quickly 'fall' back down almost like he may be struggling to swim properly or he has gone blind. What could be causing this?
<Mmm, damage from collection/shipping, genetic heritage, psychological input...>
Thought he may recover because he started eating but he seems to be in the same situation as he was when I put him back.
Any help would be much appreciated.
Reuben
<You seem faced with three options... to wait and hope, to move this fish to another system, or to give it to/place it with someone else. Bob Fenner>

Regal Tang Breathing Problem 8/5/09
Hello All,
<Hi Adrian>
I have a small regal tang (3 inches roughly?) that was first in my quarantine before my display. It was in there approximately 5 weeks, and I had used PraziPro for 2-3 days... did a water change.... then did a treatment with Cupramine because it had ich from the transport from the store to home...
<Fish do not contract ich on the way home, this fish had the infection before it left the store. Why did you use PraziPro (Praziquantel), did your diagnosis indicate the need for this particular med? This medication is generally used for treating flukes, flatworms and Turbellarians, and treating tapeworms in our four legged pets. The recommended 5-7 day treatment isn't nearly long enough to effectively eradicate ich, generally 21-28 days to ensure an entire kill. Did you monitor the Cupramine level with a test kit? Although a little safer than copper, the toxic level of Cupramine is 8mg/L with the minimal effective dose being 2-3 mg/L. Tangs are very sensitive to copper and therefore should be treated at the 2-3mg/L level. Another problem I see is combining medications, no other medication should be used with Praziquantel. I'm sure your water change did not remove all of it.>
After all of that, I noticed the fish had HLLE ( vitamin lack I believe... I try).
<And water quality.>
I then proceeded immediately to order Selcon, Boyd's Vita Chem, and Zoecon.
I mix those into it's food now in a small dish with water, as well as add some drops to the water.
<One is all that's needed.>
My question is - the fish seems to be breathing a lot faster than normal.
Did the Cupramine destroy it's breathing ability? I don't know what to do in order to judge if it's breathing is too fast - or if the Cupramine made it always breathe this fast.
<I'm guessing the fish is no longer with you by now. The rapid breathing is an indication that the gills are infested with the ich parasite causing the fish difficulty in breathing.
Generally the last symptom before death.>
The rate at which it is breathing is doesn't seem to vary much. I can't judge how many times it's moving its gills, (but it would be as if the fish swam very fast across the tank and then stopped).
I should note that I am writing this only a few hours after adding it to my main display. It was in a 40 gallon tall quarantine tank previously.
<Why on earth did you move an infected fish into your display tank?>
I have a 125 gallon display with 2 false clowns, and a 90 gallon sump. The clowns seem to have befriended it.. and they are hanging out as a group now.
Water parameters would be considered "normal".
<Mmm, I don't know what you consider normal.>
Any advice? I'm trying but I don't know what else to do other than vitamins, lots of Nori ( it isn't finding it on the clip ) and water quality.
<In the future, properly diagnose the disease before selecting a treatment.
Dosing medication that will not be effective will just further stress out an already stressed
out fish. Do read here and related FAQ's. Will help you in selecting healthy fish and in diagnosing disease and proper treatment.

Re: Regal Tang Breathing Problem 8/05/09
Hi James,
<Hello Adrian>
I'll go ahead and answer your responses if you don't mind.
<Not a bit.>
I didn't mean to say the fish contracted ich purely on the ride home - I did the treatment because I did see ich but also as a preventive with tangs.
<OK>
As for Prazipro... I had read that PraziPro can be used safely as a preventative measure as well, so that was the reason I had used it for 3 days before doing water changes to start the Cupramine treatment. There was no intention of eradicating ich with this, but rather to be sure it wasn't flukes (shaked head side to side in QT - could have been ich causing this as well).
<Would have been better just to start with the Cupramine.>
The Cupramine worked very well and all white spots were gone. The treatment lasted 15 days at .5ml and then I did many water changes.
<Good to hear.>
I observed the fish for another 1-2 weeks and saw no signs of the ich so that is why I put the fish into the main tank.
<Now it makes sense. Wish your email would have had this information from the start.>
I had also read that copper can cause a fish to breathe faster, along with having HLLE and water quality - so I assumed the main tank environment along with other fish and a proper diet would help settle it down. I still have the fish and it was breathing slower last night, or at least varying it's breathing rate from what it was before.
<Good, and hoping the tang makes it. Is it eating well?>
Water parameters are:
1.025
dKH 7.5
Ca: 460
MG: 1400
PH 8.2-3
Nitrates: undetectable
<Sounds good.>
So just wanted to clarify a few things...
<I'm glad you did. You may want to increase your water quality by filtering the water through Chemi-Pure. Do you have good water flow, say about 10x your total tank volume? Tangs do prefer good flow rates. You never mentioned your tank size, type of filtering, etc.,
makes it difficult to see the whole picture.>
Thank You,
<You're welcome. James (Salty Dog)>
Adrian

Re: Regal Tang Breathing Problem 8/6/09
Hello Again,
<Hi Adrian>
Thanks for the prompt reply.
<Welcome.>
I did mention my tank size in the first email I believe,
<Yes, you did, sorry.>
however it is a 125 gallon with a 90 gallon sump and a 20 gallon skimmer box. I have 2 MP20 Vortechs in the tank with a mag 9 return pump. I think I am going to get a mag 12 to "up" the flow.
<You have an adequate flow rate with what you have. The MP20's are impressive, very well made and expensive.>
On a side note - The tang isn't seeing the Nori I am putting in so I have moved it's position near it's hiding cave. I did place the Nori on the sand but my turbo snail mowed it down first...
<If it is eating other foods, it may well recover. I have had very healthy tangs that would not touch Nori and then some that did.>
I am also adding 4-5 drops of Zoecon to the water daily to help fight HLLE.
I then rotate Boyd's Vita chem and Selcon in the flake/frozen food.
All The Best
<Ditto. James (Salty Dog)>

Re: Blue Tang Not Acting Quite Right 05/19/09
Hello again,
<Hello Becky>
Thank you so much for your quick reply!
<We try.>
My dad just got back from the store a while ago with a 2-gallon plastic tank. I know it isn't much, but it is something. We have filled it with the water from the main tank and have put Dory the Second in (haha! Yes I know, the "second". I hope my parents will take your advice on not getting a third).
<Please do put some pressure on them about not getting a third. This fish really should be returned to the fish store when recovered. It is much too large for a fifty gallon tank. Additionally, this two gallon tank is not going to work for long term quarantine. Not only will the water quickly become toxic from the waste produced by this fish, but it is too small psychologically, even in the short term of a few weeks. Consider a twenty gallon tank or so the absolute minimum for quarantining small tangs.>
Now that my dad has moved her to the Q Tank, we can see her better and she's gotten worse from being up against that Power Head. Hopefully now she'll be able to recover that she's alone.
<Likely it was the other tang that was damaging your blue tang. Once recovered please either return the blue tang to the fish store, or find a much larger home for this fish.>
<<It will never recover here. RMF>>
No matter what happens, we have learned from this experience. Even though I'll be sad when I see Dory #2 on the bottom of the Q Tank (which I'm sure will happen soon) I know that with each mistake, wisdom is gained.
<I hope so.>
And besides, we got a quarantine tank out of this! :)
Anyway, thanks for your advice!
~Becky
<Your welcome Becky and good luck

Re: Regal Tang Breathing Problem 8/6/09
James.. you won't believe this....
<I bet I will.>
I saw my tang lining itself up in front of a rock and then.... you guessed it.... flashing it's side on the rock a few times... I can't believe it. I went 3 months with a fallow tank... hyposalinity for my 2 clowns... Cupramine at the proper dosage.. and now this.
<I'm certain the tank was clean after three months. The disease was introduced into the system by some means.>
I certainly cannot tear down the entire tank again. Do you have any suggestions as to what I can properly do to combat this? I know the odd tang will scratch in real life and not have ich... but I'm not certain with this one. I also know that skunk cleaner shrimp do NOT get rid of ich under the skin, but could they help alleviate some "annoyances" the tang has?
<Likely not enough to matter, as you say, they will not eliminate the parasite but may alleviate some discomfort.
My suggestion would be to quarantine all fish and maintain treatment dosage for 28 days.
This will ensure all hatching cysts will be killed. Copper/Cupramine has no killing effect on the unhatched cysts and is why a 28 day treatment plan is advised. As long as no fish are present in your display tank, the parasitic infestation should cure itself in five weeks. The ich parasites will die soon if no host is present. Any nets or other cleaning tools should be sterilized in a solution of 20% chlorine bleach and 80% water. We do not want to transfer any disease into the display tank by way of implements. Have you read here?
http://www.wetwebmedia.com/ichartmar.htm>
Thanks for all your help
<You're welcome. James (Salty Dog)>
Adrian,

Re: Regal Tang Breathing Problem 8/7/09
Hi James,
<Adrian>
There are only 2 possible solutions then. The hyposalinity treatment either did not work (months ago),
<No guarantee's here, just a preferred first step.>
or the Cupramine treatment did not work. With that said, I did properly calibrate the refractometer before I performed hypo on my clownfish. They stayed in there for 3 months! Tank had no fish...
As for the new tang - I only held Cupramine for 15 days because the bottle says 14 days and then get all of the chemicals out of the tank. Are you saying that I should extend Cupramine treatment for 28 days at .5 ?
<To ensure a total kill, yes.>
Other than that, I do not how to transfer the fish from the QT to the main tank? I simply used a clean net (after Cupramine treatment) and netted the fish, then let it down into the main tank. All of this of course, under the presumption that the ich was killed off, and not thinking ich could attach to the net during a transfer..
<The parasite can attach to and be transmissible by any wet object. Is a good practice to make sure the net used is sterile before transferring the fish back into the display tank. I say this only because some folks have multiple systems and may use an infected net in "clean" tanks.>
On a side note - the fish is still breathing slower, no more scratching, and one tiny white dot I did see near it's tail is no longer there (hard to tell otherwise.. you think you see little white dots under the skin from certain angles) I'm not certain as to whether or not it was ich because I have seen little particles stuck on a fish for some time and then when the fish swims fast or changes direction suddenly it clearly falls off. So I'm quite stumped as to how the ich got back in the tank... sigh.
<I'm thinking you did not read the article I linked you to. Will explain the life cycle of
the parasite. Also go to and read the links posted at the end of the article, "Steven Pro's excellent ich articles".>
I think catching them all again would be very stressful? I also do not know how to measure the Cupramine levels in the quarantine tank once a water change is done.
<You must use SeaChem's test kit, it is designed for Cupramine. The tests should be taken twice daily to ensure and effective dose is always present.
There are different copper test kits on the market, some measure copper, some measure chelated copper. Using one of the later kits can result in erroneous readings.>
This could of contributed to the original HLLE on the tang.
<?>
I had gotten the copper level correct measuring with SeaChem's test.. and then left it at that because I wanted to be certain the copper level always remained around .5.
<Ah, good, you do have the SeaChem kit. Again, test twice daily to ensure the recommended dose is present.>
If you could offer some advice that would be great.
<I had given you plenty of advice, read the articles I linked you to, more reading,
less writing. There is no easy way out.>
I think for now since the tang is calming down.. I am going to leave them in the main tank for now, using garlic and vitamins boosters... as well as add a couple cleaner shrimp to help with some alleviation.. if it doesn't re-occur then it should be alright... if not... I'll have to net them again.
<OK, you're call. James (Salty Dog)>
Adrian

Re: Regal Tang Breathing Problem/Not Reading/Remembering  8/8/09
So if I understand you correctly James in regards to transferring the fish,
I should:
1) Net fish from QT
2) Place fish in bucket or some sort of transfer holding tank
3) Sterilize net (while fish waits in bucket)?
4) Scoop fish from bucket and place into DT?
<I've only mentioned item 3. You are making this more difficult than it actually is. All I was eluding to is not to use a "dirty" net in other tanks to prevent disease transmission. We have already been through sterilization a few threads back. My personal method is to keep my net in a container of Methylene blue and fresh water for a few days after use, then rinse, and hang to dry.>
Wouldn't the parasites fall into the water (in the bucket from) when being transferred from the quarantine tank?
<When the transfer occurs, there shouldn't be any parasites in the quarantine tank if treated properly.>
Then when I scoop the fish from the bucket they would re-attach themselves to the sterilized net? I'm not sure why I'm having a hard time getting the right steps down.
<Same as above.>
I did read the article, perhaps just so much information at once :)
I was also under the impression that using Cupramine for over 14 weeks would permanently damage the fish. Otherwise I would have used treatment longer.
<If the Cupramine dosage is maintained for 28 days, the disease should be eradicated.
My addition amounts to 4 weeks. You need to go over the links I've provided, all information is
explained very clearly. We just do not have the time to take individuals by the hand and walk them through everything when the referenced information explains all.
We are all volunteers here at Wet Web Media, and our time spent answering queries is usually limited to a couple of hours a day.>

Worms?   5/17/09
Hello crew,
I have searched your website for answers, and the best that I can come up with is that I am dealing with some sort of worm.
<Is possible... or a microsporidean or such>
I have attached a photo of the fish that seems to be having the issues; and I circled the "spots" in question (the fish only has two of these spots). The spots seem to protrude from the fish roughly 1-2 millimeters and are white in color. There are no other fish in the tank with any bumps, spots, or any protrusions from the skin. I ruled out crypt when I noticed that the "spots" were protruding that far from the fish, and when the spots remained after a couple of days.
This fish contracted crypt (due to a non-quarantined new arrival- I won't do this again)
<I hear/read you>
in December of last year, and was treated for a month in quarantine (with all of the other fish in the tank). After the treatment, I kept the display tank fallow for another month (for a total of two months)
before adding my fish, slowly, back into their original homes.
My aquarium is a 155 gallon bowfront with the following inhabitants:
1 Hepatus Tang (I have had for about 4 years- this is the fish with the "spots")
1 Sohal Tang (I have had it for about 4 months)
<Feisty>
1 Marine Betta (I have had it for over two years)
2 Ocellaris Clowns (I have had them for about 4 years)
1 Queen Angel (I have had it for about 1 year)
And 1 Clown goby (I got this fish with the ocellaris clown, about 4 years ago)
I also have many various corals and snail, hermit crabs, and a brittle star.
My tank parameters are Ammonia-0 Nitrites-0 Nitrates-0 PO4-<0.1ppm PH-8.0
For filtration, I have a 20 gallon sump and a 10 gallon refugium. I use no mechanical or biological filtration, but I do utilize a Seaclone skimmer (I have found this skimmer to be hardly useful).
<It is. I'd be upgrading... see WWM re>
I used to grow Chaetomorpha in the refugium, but within the last two weeks all macro algae growth has seemingly ceased (this has me puzzled). My only guess is that there just aren't enough nutrients to support the rampant algae growth that I used to see. I have also packed the display tank full of the Chaetomorpha to aid in filtration, and I built caves out of it to give my Betta caves to hide in.
If you have any ideas about a positive ID,
<Not w/o dissection, the use of a scope... but...>
and a treatment, please let me know. The fish is still eating well, and I have a small stock of Metronidazole on hand if it is needed.
Thank you very much for your assistance.

Not looking good for my baby Blue Tang 5/13/09
Blue Tang/Health

Hello,
<Hi Chris.>
I have a 55g saltwater tank. This tank has in it 1 Blue Tang, 1 clown fish, 1 Scooter Blenny, (now) 1 damsel & 6 crabs. I got her on Sunday, 2 days ago, and she did very well at first. Monday, I changed 20% of the water, this was the first water change I had done in the seven weeks since I started putting fish in the tank. (Yes, big mistake I guess.)
<Better late than never.>
I noticed that the blue yellow tail damsel I had in the tank until today, was really aggressive toward my baby tang.
<Can be the nature of this fish.>
Sunday night she came up with one white spot, this morning she had several. So I took her from the tank and put her in a container to go with me to work, to keep and eye on her and go to the pet store for them to see.
<Bad move here.>
After just one hour, she seemed to be much better. The spots went away and she seemed happy. The manager of the pet store advised me to treat her for ich. After much drama to find Ich-Attack, I put a small amount in the container she was in
<I do not like the sound of this.."a small amount".>
and had my husband pick her up from my studio. He put her back in the tank for me, as I thought she would be ok. I also raised the temp of the tank to 78/80 and turned off the lights, as I was advised to by the manager of the fish store. Now that I have taken the blue damsel out, the spots seem to be subsiding.
Great, but she is very lethargic and appears to have a hard time coming down from the top. She is breathing and will move if provoked. Any advice on what I can do next? This tank system was a present for my 6 year old son (He wanted a killer whale and we settled on Nemo) and he would be heartbroken if anything happened to her, as would I. (p.s. if I would have known that she was only 2 weeks at best
<If you mean two weeks old, I can guarantee you the fish is much older than that.>
when I saw her, as I found out today, I would NOT have gotten her.
<I'm guessing your Blue Tang is about one inch long, and at that size, are nearly impossible to acclimate to captive systems.
I might add that in my opinion, Ich Attack is worthless for treating ich. Copper is an effective treatment for ich, but a tang at that size and poor health likely would die from any copper exposure. Transporting this fish
to your job in a container didn't help matters, just added more stress to an already stressed out fish. My advice is to research fish before buying, ensure you can provide the environment/care they require, along with compatibility and size issues. James (Salty Dog)>

Re Not looking good for my baby Blue Tang 5/13/09
Blue Tang/Health

Hello again,
<Hi Chris>
Well, I was up all night checking on my tang. She seems to be doing much better, now that I have removed the blue damsel. She is becoming more active and starting to eat again. Her color is coming back and the white spots are going away. She appears to be much happier now. I am hoping that she is on her way to recovering.
<Keep your fingers crossed.>
Thank you for the advice.
<You're welcome.>
I am pretty confidant in my ability to care for this little fish and feel she is in good hands. I did do a lot of research before starting this tank and have had no other problems.
<Wishing you the best here. James (Salty Dog)>

Regal\Hippo\Pacific Blue Tang Health: Reading\No Useful Information 4/2/2009
<Hi Nicole>
I have a blue hippo tang and he is laying on the bottom for the tank breathing hard and his tail fin has turned a reddish color.
<Not good, likely an infection>
He is also going to the top of the tank every so often and bobs up and down spitting water. I have tested the water and taken the water to professionals to test the water and there is not a single test that shows any water problems.
<How big is this tank? How is it set up?, and what else is in there with it?>
I have never seen the fish eat but I put seaweed in the bottom of the tank and has disappeared I am not sure if he is eating though.
<How long have you had this fish?>
I was thinking that he might have ick so i changed water and put in an organic Ick Attack.
<Hmm, no, this is not a sign of Ick: read here:
http://www.wetwebmedia.com/infectio.htm >
Not thinking he's going to make it but any suggestions what could be the problem?
<Need more information than what you have given to best answer your question. In the short term, get the Tang out of your main tank and put into a quarantine tank and start treating with an antibiotic such as
Maracyn.>
Nicole
<Mike> 

Re: Regal\Hippo\Pacific Blue Tang Health: 4/3/2009
Hi Mike
<Hi Nicole>
The tank is a 110. it is equipped with a wet dry filtration system. The other life is:
a sea anemone <What species? These can and will sting fish.>
horseshoe crab <Dismal survival chances in an aquarium, read here:
http://www.wetwebmedia.com/hshoecrabsart.htm >
4 in damsel <Species?>
1 in damsel, <Species?, Potential grouper food>
2 in yellow Tang,
1 in Clarkii Clownfish, <Grouper food>
1 in Clownfish <Grouper food>
7-8 in panther grouper. <Needs a big tank - 200+ gallons Read here:
http://www.wetwebmedia.com/basses.htm >
I have had the hippo tang for about 2 weeks. Have a feeling the fish was sick to begin with. it is a large one 7-8 inches <If wild caught, at a size that does not adapt to captivity easily>
<OK, we have a bunch of potential causes here. It is possible the fish was sick to begin with. Hippo Tangs do tend to be more delicate than others.
That said, there are a few possible causes in the tank. Possible sting from the Anemone, harassment from either the Damsels or the Grouper.>
<Again, please get the fish into a hospital tank and start treating for infection.>

Hippo\Regal Tang Health: Quarantine 3/26/2009
Hi Crew,
<Hi Alex>
I just discovered your site and the amazing amount of information it contains, what a wonderful resource for those of us seeking knowledge!!
<Happy to hear you find it useful!>
I've spent the last eight hours reading through numerous threads and I only wish I had found your site prior to purchasing a Blue Hippo Tang; for now I realize the mistakes I have made up to this point, and I could have surely avoided what might turn into a big problem.
<Ok, lets see what the problem is.>
I have a 125 gallon tank with a 25 gallon sump, mostly fish and a few corals (Xenia and Zooanthids.) I never realized the importance of a QT for new arrivals until now, you have truly enlightened me to the point of change.
<Sadly, this is a lesson that is usually learned the hard way.>
My question is regarding the Blue Hippo I purchased yesterday. Prior to purchasing I did a little research (not enough) regarding compatibility, diet, behavior, and general info on this beautiful fish and decided he would be a acceptable addition to my tank. I read they are more susceptible to marine ich than most so I was careful to make sure he looked healthy before purchasing and was assured by the LFS owner that the fish was quarantine for several weeks upon arriving in his store,
and has been eating and healthy for 2 additional weeks since leaving quarantine.
<Sounds encouraging so far.>
As he was ringing me up he went into long detail about drip acclimating (which I always do for several hours already) and feeding the fish with garlic soaked food to prevent an ich outbreak.
<I personally have doubts about garlic preventing Ich.>
Garlic was a new one to me so I wasn't sure what to make of it, but the LFS owner swore by it and told me all the success he has had in the past treating ich using garlic, so I purchased a bottle.
<Fair enough, it certainly cannot hurt.>
On the drive home the excitement of purchasing the fish started to wear off and I started to get a little nervous. All this talk of ich and preventative garlic and previous ich in the LFS was far different from any previous fish purchase I have made and
it began to spook me a bit.
<Understandably>
Upon getting home I got even more nervous when I noticed the Tang had gotten kind of scraped up during his attempt to avoid being netted at the LFS (he tried to hide by wedging himself under a rock.)
<Very common>
When I started the drip acclimation, I decided it might not be a bad idea to try do something now to help prevent my new little buddy from getting ich, so I thought adding some medication to the water might not be a bad idea.
<It was a bad idea.>
Since it was 7:30 pm by this time I had to go with what I had on hand, which left two choices: Copper or Acriflavine. I figured Copper might be too harsh and stressful since he wasn't showing any signs of ich and would be in the acclimation tank for the next few hours so I went with the Acriflavine which I had used with success in the past on Discus and was also for marine use.
<It does not treat Ich>
I added a few drops at a time to make sure he didn't negatively react (in an obvious way) to the medicine until I got to about 1/2 teaspoon then used the incoming drips to slowly dilute the water during the acclimation period of two hours. He didn't seem to be overly bothered by the process.
<Good.>
This morning he was swimming around the tank getting used to his tankmates and began eating the garlic soaked food enthusiastically, however the scraping on body looked worse than it appeared through the plastic bag upon his arrival last night. He has white patches (abrasions not the salt grain look of ich) so I'm afraid he is more susceptible to an ich breakout. I run a UV Sterilizer on the tank 24/7 and have never had any ich outbreaks in the tank since inception 4 years ago so I'm fairly sure there is no ich in the system unless it has been introduced by the Tang. What has me concerned is that after reading through your site I now understand the lifecycle of ich and also the trouble it is to properly treat once an outbreak has begun. It seems to me that garlic might offer an infected individual some benefit in fighting off an infection but it would do nothing to eliminate the parasite from a system once introduced, so if the LFS owners method of ich treatment is garlic then I think I'm in trouble. Since the Tang was in a tank with some coral and shrimp at the LFS there couldn't have be any copper treatment in the system. On to my questions:
1) I read on your site that Acriflavine isn't an effective treatment for ich but do you think a two hour bath in a highly concentrated solution would have any effect at killing the ich parasite if it were present?
<No>
It appears it might have removed his slime coat so the stronger concentration might have made it to the target.
<Removing the slime coat makes the fish more vulnerable to infection, so you do not want to damage the slime coat any further.>
2) Since by the time you respond to this e-mail he'll have been in the tank for over 36 hours is there any reason to try to remove him now or am I past the point of no return.
<I would not move or stress this fish further unless you actually see signs of Ich or an infection from the scrapes.>
I thought about trying to remove and quarantine the Tang today but I have around 150lbs of live rock in the tank and catching him would more than likely be impossible and only stress him further and probably lead to more abrasions so I decided to write to you first.
<I agree, leave the fish be and observe. With a good diet and good water quality, it should heal up fairly quickly.>
3) If removing him is your suggestion do you have any tricks to netting him?
Thank You so much for taking the time to respond, and thanks again for the wonderful site. I'm confident with your sight as a reference I'll avoid making many truly unnecessary and preventable mistakes in the future.
<Happy to help>

Re: Hippo/Regal Tang Health: Quarantine 3/27/2009
Thanks for the reply Mike,
<Hi Alex, no problem.>
I guess my most pressing concern is trying to avoid introducing the ich into the system.
<Ich is already in your system and has been since day 1, the trick is keeping all of your livestock healthy enough so it does not overwhelm them.>
Since the article on the lifecycle of ich says that it spends seven days on the host fish growing and multiplying before popping and spreading.
<This is true.>
I was curious if I have an opportunity window of seven days to remove the Tang if he starts showing signs of ich.  OR, if it's already too late and if the ich was introduced via the Tang is already there and removing him would be of no value.
<Removing the fish would be of no value at this point, unless it actively shows signs of Ich or starts showing signs of infection.>
Thanks

Ich 03/26/09
Another question, sorry!
<Mmm>
My hippos has ich, as does my Foxface etc.... I assume everyone is screwed at this point.
<Double Mmmm>
Anyways, I was told by everyone that NO MATTER WHAT Hippo tangs will get ich over and over. NO MATTER WHAT!
<... No, not so>
So I am thinking of the best course of action right now. I dread the thought of leaving the tank fallow for 2 months, and then having to buy another tank to treat the infected in (smallest size?) I have a 29 gallon in my crawlspace right now but with my small house I am wondering where the heck I will put it and will it be big enough?!
<Should be>
I will be very upset if I do the whole treatment of curing the fish while fallowing the tank and then I put the hippo back in and it gets ich again as I am told that is what will happen.  I know you are thinking this is what you get for not QTing, but I did
QT. My tank is new (not new to me but brand new) and these are the first fish added after QTing. I don't know where I went wrong?
<Happens>
I am so pissed right now. I wanted a really nice system and bought a super nice looking stand, bubble king skimmer180, 2 Vortech MP40's, etc... My total must be near about 8000.00 right now. I feel that if the ich knew that they would just die a horrible death and leave me with a nice tank. But NOOOOOOOO, that is not the case.  So I guess my question to you is if I go through the hassle of QTing/ medicating again! will the hippo just get ich again when added back to the tank starting this whole saga over again for me?
<Is possible... however... there are some better approaches to treatment that might work>
Should I flush it down the toilet now? ha ha, not really.  And what do you find the best treatment for ich?
<Heeeee! Sorry... Maybe quinine for you here:
http://wetwebmedia.com/quinmedfaqs.htm>
Hyposalinity or copper, and if copper what brand is best to use? Is there a copper that is a tad safer?
<Mmm, yes... please take a gander at WWM here... chelated varieties, brands... matching test kits...>
I want to make sure I kill the ich dead, but not the fish!  I am so sorry for the rant, you must get tired of all the questions
from people. I have Bob Fenner's book on order, I have a few sw books already but the more you can read the better I figure.
<Mmm... perhaps. Gots to toss in the proviso that we are indeed time-limited, task directed only to extents>
Thank you so much for your eagerly anticipated answer!!
Penny
<Sorry for the delay Penny... am out of the country diving, making pix. Bob Fenner>

Re: Ich 03/26/09
Thank you very much for your answers. Sorry again for the rant. Who knew this could be so frustrating???
<I'll admit to knowing the likelihood... but, am hoping we can help you get beyond this trouble...>
I am going with Seachem's copper treatments with the matched up copper test. Hope that does the trick for the sick fishes.
<Sounds good>
Can't wait for your book to come in the mail, should be today!

Seemingly ill Blue Surgeonfish 3/25/2009
Good day WWM crew,
I have a concern regarding one of my long time fish and I was hoping you could help me with some ideas.
The problem is regarding my pacific blue tang / Blue Surgeonfish / Paracanthurus hepatus. The fish physically looks healthy (no odd markings, scale problems, bloating, discolouration, or fin problems) and yet it is acting as if it will be dying soon (swimming upside-down in quick bursts and mostly laying in vertical stillness in corners of the tank; as well swimming in strange circular patterns when it appears to get spooked).
<Yikes... I hope I am not too late...>
I noticed that approximately two months ago, the fish became very passive (basically overnight) usually staying in the back corner of the tank and only coming out to eat. Due to its healthy physical appearance, I was hoping that the fish was doing this on a temporary basis. It kept this act up until the other day (which I did not like, but I could not think of anything that would be wrong with it). It was about a day or two ago that it started to act very strangely as mentioned above.
Any help regarding this would be much appreciated. I feel that the fish may not recover, although I still hold some hope. Please note that as I mentioned above, the fish physically looks as healthy as I've ever seen it.
<Something is very wrong if this fish is inverted... I would be checking your dissolved oxygen, or better, just executing a large water change, lowering your spg, adding circulation, surface agitation... This tang is easily mal-influenced by low DO... this is likely the problem here. Bob Fenner>
Tank overview:
72 Gallon tank with 1/5th live rock and about half a dozen small-medium corals (none with strong stinging capabilities).
5 fish in total including 2 clownfish, an angel fish, a yellow tang, and the pacific blue in question. The tank has about 3 hermit crabs, 5 snails, and 2 brittle stars.
Water quality is not perfect but is fairly good. It has been fairly consistent for over a year.
The tank has been running with very few changes for around three-five years now.
The sturgeon fish in question has been living well in the tank for over two years now. It was about 5cm in length when it was added to the tank. It is now roughly 12-15cm in length.
In terms of lighting, the tank has 2 150W 10k metal halides that run for approx 9h a day, and two 96W actinic power compacts that run for a total of 11h per day (on 1h before the halides and off 1h after the halides).
Tank temperature is maintained around 78F + or - a degree through the course of the day.
Filtration and water flow in the tank includes: A UV sterilizer, protein skimmer (always on), canister filter (always on - currently on a variable flow output, but had been maintained on a constant flow up until a month ago), and a pump (always on) for additional water circulation.
Fish diet currently consists of two types of flake food (not the best diet I know...). Those are Prime Reef Flakes and Formula Two Flakes, by “Ocean nutrition”.
In terms of tank deaths, it has been over a year since I've had a fish die, and about 6+ months ago a clam I had in the tank died off.
I believe that about covers the situation. Any thoughts would be much appreciated.
Take care guys,
John

Regal Tang Wound?   1/7/09
Hi Crew,
<Reuben>
Firstly just wanted to let you all know that your site is awesome!
<Thank you>
My question is regarding a Regal Tang about 3 inches long that I've had in my tank now for around 8 months. A couple of days ago while feeding it i noticed that a white scab around the size of a small fingernail had appeared on one side,
<I see this in your photos>
this then developed into what looks like a wound,
<To me too>
almost like a piece of flesh has been eaten away, along with this a couple of small blood coloured patches have appeared on the skin just in front of the gill and ive also seen it scratching up against some of the rocks and scenery, other than that the fish is acting completely as normal (eating like a pig & darting about all over). I looked it up and so far haven't been able to find anything that quite matches it, so I've come to you all for your expertise.
Tank parameters are:
Tanks been up & running for 1 year
65 gallons
PH 8.3
Ammonia 0
Nitrites 0
Nitrate 80 ( I tested the water after i noticed the scab and have been
performing water changes to bring it way back down)
Temp 79 degrees Fahrenheit
SG 1.024
Red sea prism deluxe protein skimmer
Canister filter for 105 gallon tank
Extra power head for added flow
UV sterilizer
Two air stones
Sand bed is about 2 inches deep and is made of crushed coral
Inhabitants
2 Ocellaris Clowns largest is 1.5 inches had for 10 months
1 six line wrasse about 2 inches had for 10 months
<Mmm, the most likely culprit>
1 Yellow Tang about 2.5 inches had for 8 months
1 Pacific Cleaner Shrimp had for 9 months
4 Turbo Snails had for 9 months
A few other cool hitchhikers including Feather Dusters, a Button Polyp & a clam like crustacean
I feed the fish marine flakes & dried seaweed daily and a bit of frozen food like mysis & brine shrimp once every other week.
All the other inhabitants are fine and I've never had any problems other than a brief outbreak of Ich not long after i started the tank up which killed off my Royal Gramma and a Fire shrimp which had trouble molting and ended up dying the following day.
I've attached a few photos if they're any help.
<They are definitely>
If you've any idea what it might be and any treatment for it I'd be most grateful as I've grown quite attached to it and wouldn't want to lose it.
<Is most likely a physical injury... a wound as you surmise. I would do nothing treatment-wise here. Good maintenance and nutrition will show this fish improving with time. Bob Fenner>
P.S once I've sorted out the water quality and the problem with my regal tang I'd like to add possibly a couple more fish and inverts do you have any suggestions?
<This 65 gal. tank is already past full temperament-wise... part of the reason here... I would add no more fishes>

 

Hippo Tang/Health 1/6/09
Hi crew,
<Hi Derek>
I got a Hippo Tang 1.5" at a LFS during Christmas sale, and did not quarantine it, now I fully regret it. It seems to have developed some kind of erosion around its stomach. I've read your forum and it doesn't seem to be HLLE. Not much on the face and lateral line, but erodes/ scar more on the stomach area (greyish white). The LFS told me to get it out and dose it with some antibiotics, and if not dose it with Marine Melafix.
<Melafix isn't really an antibiotic, and quite frankly, in my opinion, is utterly useless. What it can/will do is damage to your denitrification process.
On another note, do not dose medication unless you can identify the symptoms and then only dose with the proper medication. If an antibiotic is needed, you would be better off using a product containing erythromyacin such as Maracyn. Bob may have additional suggestions.>
<<No sense using antibiotics here period. RMF>>
I've tried using nets, fish traps, bottles and still couldn't get the sucker out. Since I can't get it out, I turn<ed> off the skimmer and dose Melafix daily,
<Stop dosing this, you will likely be causing more problems.>
but it doesn't seem to be improving. Its still eating like a champ, eating mysis, brine, Nori & flake.
I have a 75g tank with 150lbs of live rock, housed in it is a 3" Yellow Tang
(I've seen bullying and territorial dominance),
<Not uncommon when mixing tangs.>
2 False Percs, 1 Algae Goby and one Dragon Goby.
Water parameters seems to be quite good, should I take any other action?
What do you think the parasite/ erosion would be?
<The pic isn't that detailed for an accurate diagnosis, but my first thought was that this
fish has been in a few scuffles with the Yellow Tang and likely got these bruises from barreling into a cave/crevice. If you could get a clearer pic, it would be more helpful. For now, just keep a close eye on the Hippo.
When writing to WWM, please capitalize all proper nouns including "i" as it saves us
much time if we do not have to do this before posting.>
thanks a lot
<You're welcome. James (Salty Dog)>
Derek

<<This is very likely simple mechanical injury as James suggests... No use "treating"... Bob Fenner>>

Re: Hippo Tang/Health 1/12/09
Hi salty dog,
<Yikes, my name not in caps.>
I believe you are right. The scuffs are from the Blue Tang trying to wedge himself into caves/ crevices. The blue tang disappears after the lights go off and hides in his favourite cave. When the lights come on in the morning, the scars/ scratches usually worsens. (any idea why this is?)
<In my experience, Hippo's generally try to wedge themselves into the tightest possible
crevice and this is more than likely why you are seeing this.>
Since your last email, I've stopped dosing Melafix,
<Good, green tea extracts don't do much as far as anti-biotic remedies go.>
and ran carbon to remove it. Knock on wood the scars have been almost gone, and I'm still continuing to feed him garlic.
<OK>
I have heard from other fellow reefers that by putting a mirror in front of the tank, an aggressive (in my case a yellow tang) tang will knock themselves out by chasing after their shadow. In turn will lower the fish's aggression. I'll try this once the blue tang is fully recovered.
<Doesn't hurt to try.>
Thanks again,
<You're welcome. James (Salty Dog)>

Black spot, maybe not   12/26/08
Hi there,
<Hello Dan>
Sorry to be a bother, but I have a confusing situation over here. I have a 90 gallon reef tank with; yellow tang, blue tang, two clown fish, anemone, clam, cleaner shrimp, sally light foot, purple lobster, leather corals, hammer corals, some polyps, mushrooms and other bits and pieces. As well as about ten, well established mangroves growing in my sump refugium.
Everything was going quite well until I added a yellow eyed Kole tang (which I do love) to my reef.
Two weeks later I noticed black bumps and some color fading appearing on my blue tang. As well as some lateral line and forehead peeling on my yellow tang. So I went on the Internet and found your site. I think my blue tang has the black spot disease,
<Mmm... actually... you would very likely see this now, concurrently on the Yellow, Zebrasoma flavescens... I think you may be witnessing
Microsporideans... not really treatable... and not very debilitating>
but I didn't notice any info about the spots kind of bumping out a bit,
<Good description... and likely shiny, kind of shaped like cones... whereas Paravortex is dull, flat...>
and one day he was fine and the next he has 20 spots on him. So I am guessing I need to quarantine him, but what about the Kole (who is fine except for only eating off the rocks so far) and yellow tang?
<Again... or for emphasis, I would NOT move these fishes... at least as yet...>
I think I can deal with the yellow tang as it seems as his peeling is do to poor water quality
<?! What leads you to think this?>
and stress. I am about to do a water change and hook the skimmer back up (after two years off due to the mangroves).
<I would>
Should I quarantine all of the tangs? can I do them all together? What product would you recommend?
<No, yes, None>
Could I do it in my mangrove tank or will the medicine possibly hurt them?
<Depending on what's used, yes>
Sorry again and thank you for your help. I have never had a sick fish before and was upset to see him, I do have a good photo if needed and also don't know how to find this page again.
<Mmm, should be here with your message/response. Please do send the image along>
Thank you
Dan
<Welcome. Bob Fenner>

black spot, maybe not 12/27/08
Hi there again Bob.
<Dan>
I was worried about waiting another day to treat my fish, so I made a executive decision and went against your advice to wait to move the three tangs into a quarantine. I see why you said wait as it does seem to cause a lot of stress (for the fish and my girlfriend and I) to try to catch them.
I was only able to catch the infected blue tang, but did so without disturbing my reef which seemed good as I have seen what happens when you start moving rocks around. I went to my LFS and showed them the same photo of the blue tang I sent you,
<I still haven't seen this image>
and he told me to quarantine all three and to treat the fish with aquarium
Munster proto Marin Intensiv,
<What are the ingredients here?>
which I did do. I was reading the instructions and noticed that it said nothing of treating black spot or Microsporideans. I know I should have waited until you saw the photos but he seemed to be getting worse and I wanted to get him treated as soon as possible. I have the feeling I am not treating him with the right medication. What should I do now?
<...>
I know you will have probably answered all my questions in my second email but just in case, should I keep treating him with the proto Marin, and if not than what?
>... nothing<
should I catch and quarantine the other tangs?
<... already answered>
What about the other fish?
<... How would I, anyone be able to determine what is actually going on here?>
I have been reading about dips - would you recommend doing this? and should I keep my fish quarantined for 4-6 weeks? also I have a Marineland hot magnum that came with cloth like filter like those in vacuums, would this work for my hospital tank? or if not could I fill it up and run it with the sponge filters? Sorry for going ahead as I have read some of your articles where people did the same thing and they seemed annoying. Also sorry for two emails at once, I just wanted to keep you posted and if you thought the blue tang would be better off back in the reef tank, another day would not have gone by.
Thanks so much for all your help. I appreciate it.
Dan.
<... Please, see, read on WWM re Acanthurid Health, Protozoans, Infested Systems... B>

black spot, maybe not 12/27/08
Hi Bob
Thank you for getting back to me so fast.
What lead me to believe that the yellow tangs peeling is do to poor water quality is that, It had happened to him before and when I started trying to improve my water quality it went away. He may have started peeling before I
introduced the Kole tang, and I have noticed that a lot of the yellow tangs in LFS do have the same problems. I guess I diagnosed him with the head and lateral line disease. I did have a few mangroves slowly die in my sump a few months back when on vacation, and when I questioned the guy at the LFS about his peeling he guessed that my nitrites were high, which they were, and said it generally happens when water quality is low and they are stressed. Do you think thou I could be wrong and my yellow tangs problem could be related to the blue tangs black spots?
<Mmm, indirectly, yes... the pitting is very likely mostly due to "poor water quality"... is a type/form of HLLE...>
I should mention that all of my fish are acting normal and are as hungry as ever, thou I have noticed the blue tang rubbing a bit on the live rock. I couldn't find any information on Microsporideans. Will my other fish be affected if I do not quarantine the blue tang? I read some where to remove activated carbon, I run Chemi-pure in a hang on filter should I switch it off or change products?
<... I would keep using the Chemi-pure>
As for the blue tangs bumps, on the blue part of his body there are bumps with a black spot in the middle and around the spot on the rising sides of the bump seems to be whitish. However on his black markings he seems to only have one or two white spots, and on his fins and tail just black dots no bumps. Does this sound like Microsporideans?
<Could be... but... net cause/s?>
Is there anything I should do? Hopefully the photos are usable and helpful.
Thank you very much for your time
Dan
<Keep reading. BobF>

Sick tang...   11/19/08
Could you please help identify these for me. I am researching for someone else . From my understanding the owners of these fish had said, this appeared over night. I have seen this on other fish in the past but not able to pin point what it is cause or treatment. those fish perished.
Any help would be greatly appreciated

Re: sick tang. Paracanthurus  11/20/2008
Dear bob Thank you for taking the time to get back to me on this .Unfortunately the hippo tang passed away 24 hrs upon onset of this odd color change.. I have seen it in the past a few times. Although it tends to be common with blue hippos when they are smaller and more susceptible to disease when purchase at such a young stage..
<Yes>
All with the same signs of blackening and within 24 hrs death.. I stopped purchasing such small fish due to this similar signs and not knowing how to help.. is it possible that this could also be a similar strain of virus that appears darker on the tang?
<A virus? I don't know>
due to its natural pigment?
Please tell me your thoughts on this.. Whatever is the cause it kills within 24 hrs..
Thank you again for your time

Acanthuridae (Finrot?)   10/20/08
hi , i have a question about my hippo tang. i have had her 3 months. within the past three months i have been battling a case if ich, black ich , and now she has a white cotton looking growth on her fin.. i had put her in some quick cure but this never went away. just curious what it is? and how to cure it?
<Almost certainly a bacterial secondary infection, though a fungal infection can't be ruled out. In any case, you'll need to treat, promptly, for example with Maracyn or Maracyn 2 (I'd try the first first, and if that doesn't work, the second). Do also understand that secondary infections don't come out of nowhere, and nine times out of ten the cause is environmental, specifically water quality, though mechanical trauma (e.g., biting, poor handling) should also be considered.

Do you know what is happening to my fish? :'(   10/8/08
I was referred to you by Penny at Aqua Corals,
<A very fine retailer, individual in my estimation>
I e-mailed her to find out what is happening to my fish here is the message I sent her explaining the problems I'm having...
Penny,
Here is a picture of my Blue Hippo Tang it looks like something took a bite out of the top of the fish and all the tissue around it is decaying, I also have a Tang whose left fin and side has turned white and also looks like it is starting to decay. The fish were is perfect condition Sunday night,
<!>
on Monday morning the Blue Hippo had a small piece missing and was white all around, today a much larger piece is gone and the white has spread further down. Do you have any thoughts on what might be causing this.
<Something (frightening) that is very aggressive...>
I had thought it might be possible that they got into a fight but they have never been aggressive with each other or any other fish before, and they are not avoiding each other either.
P.S All the other fish in the tank seem fine. Thank you again for your time.
Penny thought you may be able to help, I appreciate any suggestions or help you may be able to offer, thank you.
Sherri
<Again... this very rapid onset troubles me... IF the fish was somehow "bitten"... perhaps by a hidden predator (e.g. a Mantis/Stomatopod) or another fish, to have decomposers (bacteria, fungi...) reduce it to this condition in this short of time... is troubling. Do you have another system you might move it to? I would utilize a pH adjusted freshwater dip and formalin dip/bath, with aeration enroute... in the hopes of arresting progress here.

Possible Hole-in-the-head in a Hippo tang. More   9/29/08
Hello WWM crew,
<Miguel>
I'm new to the salt-water part of the hobby and I'm trying to figure out how to help this little guy/gal. I would like to narrow down what I'm treating before I use any medicines. I unfortunately started the tank before I found your great web site and I hope I'm not screwing up too bad.
The set up: 75 gal tank started July 2008, 80 lbs live rock, 100 lbs fine Oolite aragonite live sand (live sand not really necessary/wasted extra money after reading your site), Prism deluxe protein skimmer (purchased before reading your reviews and planning to upgrade), Magnum 350 canister with a micron filter changed/cleaned every week or two depending on conditions.
<Part of the issue here>
Once a month, charcoal used in Magnum for a couple of days ( 2 to 3).
<I'd just leave the carbon in>
The outlet hose of the magnum goes through a "squid" unit (Switching Current Water Director and I have two Maxi-Jet 1200 power-heads attached to a Red Sea Wave maker.
The latest water parameters: Temp 80F, Sp Gr 1.025, Amm 0, Nitrate 0,
<Really? Surprising>
Nitrite 0, pH 8.4, Alk 3.92, Ca 420, Phos 0, Cu 0. 10% weekly water changes using R/O water purchased from the LFS. Nothing is added without testing for it first except for Iodide (hoping to get a test kit soon) which is supplemented as per the Seachem "beginner" instructions on the bottle.
The fauna: 2 Peppermint Shrimp (which took care of a minor Aiptasia outbreak on the LR), 3 Turbo snails, 5 Red legged hermit crabs, 3 B/G Chromis, and 1 small Hippo tang ( purchased before knowing 75 gal tank is not adequate size). 1 frog-spawn, 1 button polyp , 1 Evergreen starburst polyp on a controllable area, and 1 carnation (again I wished I would have found your site before purchasing but it has grown is size).
The tang was purchased and place in a 10 gal QT. 2 weeks later it broke out with Marine Ich. The little guy went through copper treatment (Cupramine)
<... killed off necessary gut infauna...>
very well and was kept in the QT for 6 weeks post treatment. He was finally placed in the main tank and was doing great...until 2 weeks ago. I noticed a single small, white tuft-like growth on the right nares. He was getting superficial scrapes from the LR so I kept an eye on the area. The tuft remained unchanged for nearly two weeks and no new ones were appearing. The fish continued to eat and was fairly active. Within the past week things have rapidly progressed. The tuft fell-off and now there is a nice sized ulcer under the area (see picture WWM3) The fish also has lost a tremendous amount of body weight and is looking emaciated ( see picture WWM2).
<I see both>
He is still attempting to eat (Ocean Nutrition Prime Reef flakes, Frozen Mysis shrimp and Nori is offered but has never really eaten it). I noticed he is swimming with his mouth slightly open and appears not to be able to close it (perhaps from the muscle atrophy). I moved him back to the QT tank and the questions I have are: does it look like hole in the head and if so can I dissolve Metronidazole tablets in the 10 Gal QT tank.
<Mmm... not what I would do>
Is there a better antibiotic/treatment to use?
<Really... root issue is water quality, avitaminoses...>
( I'm a Veterinarian so I have access to most antibiotics)
<Mmm, though a couple of flagellates (Hexamita/Octomita, Spironucleus) are associated with these sorts of neuromast destruction syndromes, the causative mechanisms are nutritional, environmental. Even so, some folks report (indirect) success with the use of quinacrine phosphate... see WWM re>
Should the 3 B/G Chromis be place in the QT tank and treated or should I wait for any clinical signs to appear? How contagious is it to other fish if at all?
<Mmm, not so much as Tangs and Angels...>
I appreciate your help and I've learned (am learning) so much from your site.
Sincerely,
Miguel Perales.

Re: -head in a Hippo tang (follow-up)  9/29/08
Thank you for the quick response.
<Welcome Miguel>
Having gone through the information on your web site and understanding that HLLE is a multi etiology disease makes
it easier come up with a treatment plan. My plan is to increase water changes to twice a week even though the parameters seem OK. I will start soaking their food in Selcon. My problem is this, I've searched the LFS and
no one seems to carry Selcon. I'm going to have to order on-line so it will take a few days to arrive. In the mean time I do have Seachem's Reef Plus which does have Vitamins and Minerals. Will it hurt the fish to soak their food in this product until the Selcon arrives?
<Not at all. It will help>
I feel that I need to intervene soon and don't have much time to waste since the tang is losing interest in eating and is hiding most of the time.
Thank you in advance,
Miguel Perales

Hello team,
I have a regal blue tang in serious need of help! About three weeks ago I noticed that he was missing scales in a number of areas and did some reading and decided that it looked like lateral line erosion. I took a closer look at my yellow tang and saw some discoloration on his face and lateral line as well, along with some fin erosion. I did some reading and it looks as if there are a lot of mixed opinions as to what causes it.
<Mmm, not to/for me>
Some of the more popular reasons I've read about were vitamin C deficiency and poor water quality.
<This and other avitaminoses, stress>
I feed my fish formula 1 and 2 ocean nutrition flakes, frozen cubes of marine cuisine with brine shrimp, and green algae sheets and have witnessed the blue tang eating all of those, although the algae sheets are rare.
<I'd be supplementing these foods... with a liquid prep. like Selcon, MicroVit...>
I did some asking at my LFS and the lady I spoke with there suggested feeding romaine lettuce for the vitamin c.
<... no. See WWM re. A very poor choice period>
I put clips in the tank and after a couple of days all of the lettuce disappeared. I
haven't witnessed the blue tang nipping off of them but I have seen the yellow tang eating feeding quite a bit and he looks like he may be getting some color back. The blue tang has only been getting worse though, he has almost no blue left on his entire body and looks almost clear, but is still eating other foods. My clownfish, blue damsel, royal gramma, Firefish, and neon goby all appear to be healthy.
I tested water quality and specific gravity is 1.023,
<A bit low>
PH is 8.2, ammonia and nitrites are both zero, but the nitrates had jumped up to 40 ppm.
<Way too high...>
I did a quick water change and that dropped the nitrates down to less than 20 ppm and I have more water mixing for another change if they get any higher.
<You need to discern the cause, deal with this here. Very likely the "lettuce" in part>
I think I may have been overfeeding so I've cut down on how much I feed them and the water has cleared up a little as well.
I also have been battling black algae.
<Can be a factor, toxic>
I no longer get the brown algae all over my rocks but have about a square foot patch of substrate that is constantly covered in black. I'll remove all of it, but within a few hours it will be well on it's way to growing back in the same spot but nowhere else in the tank.
<See WWM re Cyanobacteria...>
My setup is a 75g fish only system. with an emperor 400 filter, powerhead and airstone for circulation, and the temperature set for 78 degrees. It has been set up for about six months now.
There have been a number of events recently that may have impacted the regal tangs health. I was having a battle with ich and conducted hyposalinity on my display tank. I had no live rock at the time so I moved my shrimp, crabs, and snails into my 12 g quarantine tank and left only the fish and hermits. The tang went two months with a salinity of 1.009 and it was at the end of that time that I first noticed missing scales.
<Another input for sure>
At the beginning I also gave him dips in RidIch with formalin
<Ditto>
but the yellow tang wasn't subjected to that. While the tank was in in hyposalinity I cured about 30 pounds of live rock that is now in my display tank and have another 30 pounds curing to be added as well.
Is there any way to encourage him to eat the lettuce?
<...>
I put clips near his favorite spots in the tank but he has been ignoring them as far as I can tell.
Thanks,
Jason

Hippo Tang   8/29/08
Dear Mr. Bob Fenner
<Akila>
I have an 80G Marine tank with 1 Hippo Tang, 1 Bannerfish, 3 Large Tube Worms, Bubble tip Anemone, some snails, a microalgae colony & lots of live rocks with coral line algae. I use 6500K 500W (4 x 125) CFL lighting. I use
a 4G Canister Filter, 5W UV Sterilizer, Remora hang on Skimmer (with 2000L/H separate power head), 2 Power heads (2000L/H), & Chiller. 
The tank is running well. I do a 20% water change every month and feed my fish and invertebrates carefully. My water parameters are Ammonia 0, Nitrite 0, and Nitrate < 20. This tank has being running well for the past 1 year.
<Ok>
Hippo Tang was in QT for 2 weeks and transferred to the main tank about 2 months ago. I have attached some photos that shows a problem that the Hippo Tang is having now. These spots are under his belly and on the side. When you look at it closely it look like his skin is coming off. I am so worried as to what will happen to my Tang. Could you please help me identify this disease and let me know of a way to help him.
Thanks in advance for your help
Best regards,
Akila
<Thank you for supplying complete information and such fine photos. This mark looks very much like a "burn"... Am almost sure it originated with a chance/accidental mishap with your BTA... It should heal in time of its own accord with your good care. Bob Fenner>

Hippo tang question, hlth., learning   8/19/08
Hi there,
I purchased a juvi hippo tang last Thursday (August 14) and he settled into my tank
<... no quarantine>
very well (started swimming about the tank, meeting new tank mates within 5 minutes of introduction)
<Good>
The tang is very small, probably as big as a loonie, and smaller than a toonie.
<Mmm, summat less than a dollar coin in the U.S.: http://www.bcpassport.com/vancouver-vital-information/canadian-money-currency.aspx>
He does have a nice stuffed belly, but he has not eaten anything since being introduced. He has shown maybe 3 to 4 spots of ich, which it tries to swipe off himself by dashing on the bottom or corners of the tank every so often.
<Mmm... you do realize the system is now infested if this is a protozoan agent?>
He is not in complete distress at all, and still is active, not breathing fast and generally looking pretty good. I am taking measures to treat the fish for the ich (trying Aquarium Munster protomarin coral, fingers crossed) I will have no chance of catching that tiny fish in my display so I am resorting to medication.
<Mmmm... "reef safe"... "effective"... Don't go together any better than licorice and pizza... and I'm a giant fan of these last two. I don't see where the manufacturer lists the ingredients: http://www.aquarium-munster.com/Eng/GB_0_Home.asp
Do you know what this material really is? If so, please send along>
My question is, after how many days without food should I start to worry?
<Daily>
I already am worried, but like I say, his belly is pretty fat. He tries to peck at floating items in the tank (thinking it's food), so I know he is trying to eat.. he just always misses out on my feedings. When I turn the pumps off, he goes running and hides the entire feed. With the few ich spots, and not eating, I am worried it's health will decline at a fast rate. I have tried feeding with pumps on, but the movement from me putting food into the tank sends my clownfish running, so everyone follows, they all get scared so easily.
<A bad sign>
I have also ordered some Kent Garlic Xtreme,
<...>
and some Selcon to start soaking the foods in, in hopes it might entice him to eat. I also ordered some seaweed algae. All these items should arrive by Friday. I forgot to mention, I am feeding my fish with NLS Pellets, and mysis shrimp soaked in garlic extract (which is better?)
<Can't say>
I don't want to lose the little guy, he is the healthiest I have found a juvi hippo. Is he going to starve??
<Mmm, maybe. Are you going to read?>
I really hope this guy starts noticing my pellets and mysis soon.... with all the extra food I am pumping into the tank for him to eat, I am getting bits of algae outbreaks. Thankfully my clowns are complete pigs and usually clean up the leftovers.
Thanks for reading my long post, I am terrible at summarizing. I just basically want to know how long without food should I start to worry, what foods I should focus on feeding (I hear the NLS pellets are a very good source of nutrition for marine fish?)
<Yes... an excellent, very palatable source>
I have been trying to feed every day, with no luck. It's not that the fish doesn't want to eat, it's just that he hides when I introduce food into the tank. I figured if all the other fish would eat, he would notice and start eating too, but no luck on that note yet.
Thanks again for a great resource.. I appreciate your time and efforts.
<A few "things" possibly going on here. "Just" being new/stressed, to being toxified by some homeopathic remedy... You don't mention your system components, history, or water quality tests... Please start reading here: http://wetwebmedia.com/paracfdgfaqs.htm

Tang Help! Hippo hlth.  08/18/2008
I purchased a thriving system from someone who was moving to CA. It has been up and running in my house now for 3mos and has still been thriving.
<<Ok>>
A 7" Blue Hippo tang came with the system when I bought it and has been a very healthy fish. I added my 2" Blue Hippo Tang who has doubled in size since adding to the system. Yesterday I rearranged the rock work and added the following;
6 green chromis
3 blue mushrooms
1 green clove polyp
1 Christmas tree worm rock on Porites
and 2 Bali tube worms
<<All sounds nice>>
Almost immediately the large Blue Hippo started acting all stressed out. Trying to find a new hiding place, even though I did not change his old one, and breathing hard. I turned off the lights early hoping to help relieve some of his stress, but he died overnight. Now my smaller Blue Hippo is missing this morning for feeding time.
<<Such a shame the fish died. Could well be just stress of the new additions as to why the surviving tang is in hiding, hope all is well with it>>
Was one of the above toxic to Blue Hippos? What could have possibly happened to cause such a fast death?
<<No, nothing there is incompatible with a Paracanthurus. Did you inspect the dead fish for outward marks, cuts, abrasions etc etc?? This would be your first port of call upon death>>
125g reef tank
All my levels are at 0
Nitrates are less than 10
calcium is 500
temp is a steady 80
salinity is 1.023
<<Was the LFS water added to the tank with the new purchases? any additives etc? There is usually a reason why fish die, and starting off giving the dead fish an inspection, can usually start to enlighten us as to what has happened. Hope this helps, A Nixon>>

Blue hippo tang can't swim  7/29/08
Hello,
<Josh>
I've used your site for years, and have found many answers to my questions, but I can't seem to find this one. Here's my problem:
I have had my blue hippo tang for 2+ years and he has battled a few attacks of ich, but never anything serious.
<How "it" was treated may be>
Recently (about 3 weeks ago), I noticed he was swimming around with his head pointed down, and seemed to have trouble swimming level.
<Mmm, not good>
I watched him for a few days and did not notice him eating. By the time I decided I should quarantine
<Not advised here>
and try to help him, I didn't have the time (was going out of town for a week). So, I regretfully left him in the display tank
<Good>
and gave him my best wishes while I was gone.
When I returned, he was laying on his side on the bottom, but still breathing. I took him out of the tank and put him in quarantine with Furazone green (the only antibiotic I have available). He appeared almost paralyzed and would flop a little bit when I touched him, but that was about it. After a couple more days, he floated to the surface and bobbed around.
He was still breathing and aware of my presence (would flare out his dorsal fin when I hovered over the tank). I decided there was no hope, so I took him out and was going to put him in a baggy to freeze him (heard this was a quick way of putting them down). But when I did, he started flopping and spit up a baby turbo snail.
<Interesting>
He was showing more energy than I had seen for a while, so I decided not all hope was lost. He still hadn't eaten anything
(probably about 3 weeks now), but I tried again with some frozen mysis.
While I had him out of the water, I put the mysis in his mouth and he swallowed it. I put him back in the water, and while holding him with my hand, I placed him in front of more mysis. He would suck them in, chew a little and then spit it back out. But after several times of doing this, he actually swallowed it! That was yesterday and I've now fed him three more
times by holding him and sticking his mouth in front of the mysis. I've seen no improvement (but he doesn't seem to be getting worse either). Do you have any idea what might be the cause and solution of this problem?
<Mmm, only wild general guesses... Could be a matter or function of long/er term nutritional deficiency of some sort, a developmental/genetic issue, some legacy of collection/handling damage, some residual chemical/treatment damage... Very likely not pathogenic...>
Could it be the baby turbo was stuck in his throat and caused all this?
<Mmm, possibly>
But why is he floating on the surface, unable to move?
<Lack of food...>
He shows no external signs of problems. No visible parasites and color is good and eyes are clear. He changed color (got pale) when I had him out of the water, so he is still responding to stress, I guess. He is very buoyant and floats to the surface quickly when I let him go. He cannot swim at all, but sometimes get a little burst of energy and twitches. I am hoping there is still a chance, since he is eating now.
<There is always a chance at living as long as there is life>
Tank is a 450 reef tank with 48 other fish.
<Ahh, then highly unlikely a deficiency syndrome... but perhaps something to do with ingesting hydrozoan, Anthozoan... material>
None of the other fish are showing any signs of stress or abnormalities. Nothing has changed recently in the tank. I've never seen any aggression towards him and he's never been aggressive towards any other fish. He's always been shy, but still got enough to eat to keep him healthy.
Nitrates = 5
Nitrites and ammonia are 0
Calcium = 400
Alkalinity = 8
Thanks in advance for any help or advice,
Josh

Tang In Trouble (Mystery Malady or???)  7/13/08
Hi,
<Hey there! Scott F. in today!>
I have had a Hippo tang for about 6 weeks. Three weeks in quarantine; three weeks in the main tank (95 gal; asst corals; several misc. fishes).
<I commend you on embracing a quarantine procedure!>
Since I placed it into the main tank, he has been mostly hiding in the live rock, with an occasional venture outsides this protection. For the past few days, he has been very lethargic. If finally have been able to "capture' him and place him in a QT. He is on the verge of death, but I would like to do whatever I can to save him.
Any suggestions?
Thanks, Fred
<Well, Fred, general lethargy can be the result of many different potential issues, ranging from poor environmental factors to disease. You'll have to do some detective work and ask yourself some questions here. I don't have much to go on. I'm assuming that the fish was eating well and showing no signs of illness during the quarantine period, correct? It is not uncommon for a fish to hide for some period of time upon introduction to his/her new home. However, for the fish to be in such severe state of lethargy, there must be something else going on. Is there a "bully" in your aquarium that is harassing this fish? Are all primary environmental parameters (temperature, specific gravity, pH, ammonia, nitrite, nitrate) within acceptable limits? Is this the only fish in the aquarium that is acting in such a lethargic manner? Are there any other telltale signs of disease, such as rapid breathing, discoloration, excessive mucus, bumps, spots, or other obvious body traumas? Has the fish been eating with any degree of regularity? I think that you're going to have to remove this fish for closer observation and possible treatment, if there is a disease to treat.
Quiet conditions and stable environmental parameters in the quarantine aquarium may help bring this fish back, but it is hard to know. Administering a vitamin product, such as Vita Chem, into the quarantine aquarium's water, might help perk the fish up a bit. Before you begin bombarding the fish with drugs, it's important to know what's going on, of course. Like I mention above, it's really tough to diagnose this fish based on the information that you described. I'd key in on either some illness, or obvious trauma as a culprit. If the condition was caused by environmental factors, the other fishes in the aquarium would have showed signs. If it is an obvious disease, such as Ich, there likely would be other fishes affected. In the end, you're going to have to get this fish into a quarantine aquarium and observe him/her closely before deciding on your next course of action. Sorry I cannot give you more specific advise, but I hope that the questions that I asked, and the fish health resources here on WWM, help you use deduction to determine what is wrong with this fish. Good luck! Regards, Scott F.>

Tang In Trouble (Part 2)  7/18/08
Hi Scott,
<Hello again.>
Thanks so much for your very interested reply.
<Hope it was useful for you.>
Addressing your concerns;
1. All other fish seem do be doing fine, eating well.
2. There is no apparent 'bullying'.
3. I keep a close watch on water quality and there is nothing out of acceptable range.
4. Ich does not seem to be present.
<All encouraging signs, to a certain extent.>
That being said, I regret to inform you that the little guy has passed on to his next life.
<I'm sorry to hear that. It's never easy to lose an animal.>
His color was not good and he seemed to be very thin. I really think that he starved to death.
<It is entirely possible. Perhaps he was subjected to collection trauma, such as improper handling, decompression sickness, chemicals, etc., which resulted in his demise.>
In reviewing the entire experience, I think that I was premature in moving him from the QT tank into the display. During the QT period, I was mostly looking for Ich (knowing how the species is susceptible to such). He may have not settled into eating well in the time allowed. Then the stress of another move was more than he was able to handle. Obviously, this is only speculation on my part.
<Yes, but you might be on to something here. Remember, the quarantine period is not just for looking for disease- it's also for "hardening" new arrivals- waiting for them to begin to eat and regain strength.>
However, I will use this experience and be certain that in the future any fish must be eating well before being move into the main tank.
<Excellent!>
Thanks again for your help.
Peace, Fred
<Sorry to hear of your loss, Fred. However, your experience may benefit fellow hobbyists, and most importantly, the fishes that we keep. Your Tang may have not died in vain. Best of luck to you! Regards, Scott F.>

Sick Hippo Tang – 07/08/08
I was told on Reef Central to send you a picture and some info and you might be able to tell me what is wrong with him. I woke up yesterday
morning to my tang growing a beard. Little white hair looking item's on its body. All my water Parameters are good, and none of my other
fish are sick(2 clown's, 1 other tang, 2 chromis)
<... Your tang has "tang"led with something... Either a bristleworm or such... or some other prickly critter. Not much to do here but provide good care, and hope. Bob Fenner>

Re: Sick Hippo Tang... lunacy  – 07/08/08
Should I put him in a Quarantine tank? What are the chances of it surviving, and contaminating other fish?

Hippo tang with Velvet? - 7/2/08
Hey guys,
http://www.zaita.com/Images/Hippo01.jpg
http://www.zaita.com/Images/Hippo02.jpg
<I see>
I noticed these marks on my Hippo today, she was fine yesterday. She seems to have a scratch in front of them going up her body as well. I thought maybe velvet, but I am thinking it's something more?
<Mmm, something different. Twere this Amyloodiniumiasis, all your fishes would be dead>
Maybe she got stuck in a rock and had to wiggle free? It is only on 1 side of her body too.
<A possibility, but there is a much greater likelihood that this area is resultant from a "brush" with the Cnidarian life in your system... perhaps the Euphyllia just in view>
Tank is 125g, 12months old. She was first fish introduced and is now about 15cm in length. No new additions for the last 12 weeks. She is housed with 2 Scopas tangs who she bosses around, a few smaller fish and a CBB whom she ignores. She rules the tank quite happily. Her appetite, attitude and breathing all appear to be normal. She is fed Nori, enriched Spirulina and enriched frozen brine. She has previously had white-spot but it was only ever 1 or 2 spots that left after a week.
Apart from that she has been a healthy blue tang. She was looking perfectly normal yesterday too.
Thanks heaps guys, really love the site and it's an invaluable resource.
Regards,
Scott.
<Thank you for your kind words Scott. I would "do" nothing extraordinary here. Very likely this area will heal w/in a few weeks, the fish all the smarter for paying closer attention to the "decor". Bob Fenner>

Re: Hippo tang with Velvet? - 07/02/08
Thanks Bob,
I kept a close eye on her that night and made an amusing observation.
The scratch running her the side of her body was also lined with bristles, very hard to see without a good light and the fish moving slowly. I am guessing she was jabbed by a fireworm (Eurythoe complanata) and then as you have suggested, must've run into a coral.
<Ahh! Ouch!!!>
She seems to have healed up for the most part already, so hopefully she will be a bit wiser in which rocks she tries to play dead against :P
Thanks,
Scott.
<Thank you for your further input Scott. BobF>

My blue tang recently got ich... no pic, data, or reading    6/10/08
Hi,
My blue tang recently got ich, it was a very small case of ich, but ich none the less. It seemed to get better until we noticed that after a while the white spots started looking less like ich, and his flipper looks like it has kind of been eaten at in places. I thought maybe it was marine velvet, but after reading up on it I figured that wasn't it. So I thought maybe it was fin rot, but after looking at the symptoms it doesn't sound like fin rot either. Any ideas?

Trouble in Paradise, Sick/Dying Tang, Inappropriate Stocking 6/5/08
Thanks in advance for any information you can give me. Your website is wonderful! This is the first time I've posted so bare with me.
<Ok>
I have a 30g tank, 23 lbs live rock, 30 lbs live sand, 8 snails, 12 crabs, two tank raised Perculas (one obviously bigger than the other but are still
duking it out),
<This never really stops>
1 chromis, and 1 Hippo Tang.
<This tank is by far too small for a Hippo.>
Water conditions are: temp 77,
pH 8.2, ammonia 0, nitrite 0, nitrate just below 5, spg 1.021.
<Would slowly raise the SPG to a more natural level.>
I cycled my tank with live rock for 4 weeks. Added crabs and snails at a little over 2 weeks (sand and rocks were covered in brown algae). I then added 1 chromis at a little over 4 weeks. Added clowns and hippo tang 5 days after chromis.
<Probably too much too fast.>
Everybody was fat, happy and eating Formula 1 flakes (this is what the LFS told me to feed). This continued for about 3.5 weeks. Last
Thursday I noticed the tang rub on the rocks and saw what looked like a couple bubbles on "her" but they went away. I didn't see her do it again
after that. This past Sunday she wouldn't come out of her cave and wouldn't eat, Monday the same thing. Tuesday she came out but stayed at the surface with her nose almost sticking out of the water and breathing kind of heavy, still wouldn't eat (see attached photo). Last night she would swim a little but for the most part stayed at the surface. This morning at the bottom, belly up with "bugged out" eyes. After reading through your website for many hours I'm thinking it was crypt/ich.
<Is common for this species.>
My question is: Do I need to do anything to the tank/other fish?
<Wait and see how badly they are infected, be prepared to treat for ich in a hospital tank.>
I went by my LFS on Wednesday and was told "that's crazy Dory for you. just keep an eye on her." Called them back today and was told she must have been stressed. Asked them what I needed to do at this point because I don't want my other fish to die and was told "I don't know just watch and see." My neighbor also had a tang from the same store displaying the same symptoms died two days ago.
<I would think about finding another LFS.>
I'm new to this and I have a very upset 4 year old wanting to know where Dory is and why are the two Nemo's fighting! (also attached a picture of the clowns)
Help!

Hippo Tang, hlth.   5/29/08
Hi WWM Crew
<Carol>
I consider your web site invaluable in resolving problems I have encountered over the years. I am so upset over the sudden loss of my Hippo Tang and hope you can shed some light on what might have happened. I purchased him as a 'baby' over 2 years ago and he has grown and thrived.
Yesterday when I came home from work there he was, my pride and joy, dead on the gravel. I was stunned. He had eaten the night before and showed no signs of any problem. I immediately checked the water parameters and everything is fine. All of his tankmates (1 clownfish, dwarf lion, goby) and my anemone and mushrooms are all OK. I checked the tang for damage and could not find anything. He did not have Ich or HLLE. I read Mr Fenner's book about changes in water temp, but that checked ok also (80)
Any idea what might have happened to him?
Thanks, as always, for your advice.
Carol
<Am sorry to read/realize your loss... there are a few sets of speculations re these "sudden death" events root causes... One that should receive credence is that fishes, though they seem "adult", compared with tetrapods (the so-called higher vertebrates) are not "genetically mature" as mammals, birds... and do often (a relative term) perish from pre-determined coded flaws... Another possibility here might be some sort of enhanced stress from the presence of your anemone and mushrooms... these disparate Cnidarians don't "like" each other, and their chemical warring does wear on fish livestock. Some input re this last phenomenon and actions that can be taken to alleviate it can be perused here: http://wetwebmedia.com/cnidcompppt.htm

Blue Tang Problems 04/05/2008
Hi All,
<<Hello, Andrew today>>
I have recently been having some trouble with a Blue Hippo Tang in my 75gal reef aquarium. It has begun scratching on the rock work in the tank more frequently than normal, and has numerous raised bumps on it, about the size of a pinhead, and a few of them are white. I originally thought it was Ich, but as none of my other tank's inhabitants (2 percula clowns, 1 coral beauty, 1 Hawkfish) have had any symptoms or odd behavior, I figured it was something else. The tang has had this problem before, though not as badly as lately and those bumps usually went away within a few days or so, but this recent outbreak has lasted about 5 days now. My water parameters are pretty good, 0 phosphate, 0 nitrite, 0 ammonia, 2.5 nitrate, pH 8.3, salinity 1.025, calcium at 450 and Alk at 8, so water quality shouldn't be the issue. I am inclined to think it is something fungal on the Tang, and if so, what should be used to treat it? I have been soaking the food in Selcon and garlic alternately to try to help out. The tang eats very well, I usually feed Formula flakes, pellets and frozen foods, I tried to get it to eat Nori and seaweed, but it refuses to eat anything off a veggie clip. Any advice?
<<Does not sound fungal to me, it does sound like Ich, and Ich that has not gone away from a previous infection. I would suggest moving the stock to QT and treat with hyposalinity and monitor all. More can be read here http://www.wetwebmedia.com/ichart2mar.htm >>
On a hopefully unrelated note, I have been having some Cyanobacteria problems for a few months now, it will grow on the rock and glass until I siphon it off during weekly maintenance, and then grow right back. Skimming through some of your files here at WWM, I read that the DOC's from frozen foods can fuel Cyano growth <<Potentially, yes>>. I usually feed one cube a day, and until very recently, hadn't decanted the 'juice' out of the cubes, would that be the source of the problem?
<<Quite possible, yes. The juice from the frozen foods contain a high amount of phosphate (even though some foods say they don't). Cyano can appear from a few things overfeeding, too much light (lighting period), high phosphate and nitrates, flow....One of these area's are providing the means for the Cyano to bloom>>
Thank you for all your help, your services are invaluable.
Kindly, Daniel
<<Thank you for the questions Daniel, hope this helps. A Nixon>>

Is an 18g Rubbermaid container too small to quarantine a 6" hippo tang? -02/27/07
Dear Crew,
Just wanted to get your advice on this, as I have been given wildly divergent advice on my local forum. They all completely advise against
freshwater dips even though I've read about it many places.
<Ah, this is the "problem" with forums. You never know who is answering your question or how knowledgeable/experienced they are or aren't. But they're fun anyway. :-) The freshwater dipping method is a bit "controversial" and there are arguments on both sides.>
I am acquiring a 6" hippo from another local hobbyist and I still debating QT/Dip methods. Thinking my 10g quarantine tank to be too small for this
fish, I went out and bought an 18g rubber maid box to use for quarantine. I am wondering, will this still be too small?
<Even if you want to debate the dips, it's pretty universally agreed that QT is generally a good idea. 18g is a bit small for a 6" tang... but it doesn't have to be a tank. You can use a rubber maid container, just get a bigger one.>
Also, I have seen many times that Bob advises a prophylactic dip then straight into the display to minimize stress for hippo tangs. Would this
indeed be a better method for my new fish?
<Truth be told, there really is nothing written in stone about these things. Hippo tangs are quite prone to ich and this is an argument for quarantining them. However, on the other hand, stress is a big "cause" of ich. Thus, reducing stress as much as possible might help prevent ich just as much or more as quarantining. Fans of quarantining will say that quarantining should be done such that it doesn't cause the fish much (if any) stress. But again, since there's so little we actually know for sure, ultimately there's still a lot of guess work/intuition/empiricism involved with these things. The best we can do is make sure are "guesses" are intelligent, well-informed ones. Personally, I would consider the overall health of the fish when you get it. If it looks really healthy (no discoloration, no fin tears, vibrant, active, good appetite, etc.), you might be less inclined to quarantine it if you think doing so would only cause it unnecessary stress. But ultimately, the decision is simply up to you.>
As for the dip, I have the 18g quarantine "tank" all ready to go, saltwater is aged and aerated. If I chose to go the dip route, could I just add Methylene blue to this tank for the dip? I was thinking that it being saltwater, it would be less stressful for the fish.
<sounds reasonable>
The only other thing I've never quite been able to grasp with freshwater dips is the acclimation process from the shipping bag to the dip container
and then to the display. Am I right in thinking that I make sure PH, temp and salinity correlate between the display tank and the dip vessel and
acclimate the fish to the display tank then put it in the dip vessel? Sorry for the dumb question, but it's something I've never quite understood.
<Not dumb questions at all. It stands to reason that the fewer "moves" you have to make, the better. So if you were going to do the dip, maybe you should do it straight out of the bag, then proceed to acclimate. On the other hand, the fish might already be so stressed in the bag, it might be wiser to "give it a break" and acclimate it before dipping it. Again, I would try to judge the overall state of the fish. If it looks like it's really stressed out, I'd wait to do the dip (do it after acclimation). I'm sorry I can't honestly give you a certain answer (no one really can). Personally, I'm not a big fan of freshwater dips in general. A lot of the parasites it's meant to kill/prevent are tough little buggers that aren't likely to die off with just a dip. Or, rather, it wouldn't kill off *enough* of them to justify the potential stress it causes the fish. But again, this is MY opinion. And there are a lot of varying opinions on this. You'll see even here on WWM, different crew members have different opinions on freshwater dips. And since there's simply not enough real formal research on any of these things, anyone's educated guess is as good as mine (or yours).>
Thanks again for all your help!

Re: Is 18g Rubbermaid container too small to quarantine a 6" hippo tang?-02/27/08
Hi Sara,
Thanks for the advice. At this stage, I'm leaning more towards skipping quarantine based on what I know of the fish. It's from a local hobbyist who's had this fish for a year in captivity. From the pictures it looks very healthy, although I will reserve judgment until I actually see it.
<In this situation (since the fish is coming from another tank where it's been for a long time, and not from a LFS), quarantining might not quite as important as not stressing the fish.>
The only fish I've lost in the short time I've been in the hobby has been a hippo tang that I got shipped. Died of no apparent cause (nothing external anyway) and so, I resolved to only buy locally and preferably from an established tank. I've included pictures to see what you think.
<Looks like a pretty healthy fish... but as you said, I wouldn't be sure till I saw him/her in person.>
IF the fish did get ich in the display, would it necessarily affect the other fish?
<Not necessarily, no. But it would make the other fish more vulnerable to it if they are stressed. These infections have a lot to do with the overall health of the fish. Generally, healthy, happy fish under minimal to no stress don't get ich nearly as easily as a stressed/ailing fish. And some fish are just more (or less) prone to it naturally. If the fish does get an infection, you should probably remove it and quarantine it just to be safe. But lets hope that doesn't happen. :-)>
Fingers crossed,
<good luck>
Dane
<Best,
Sara M.>

Fin Rot? HLLE? Data?   -02/20/08
Hello again WWM Crew!
<Mike>
I have an issue with our blue hippo tang. A couple days ago she started swimming with her dorsal fin fully extended and it has stayed that way ever since.
<Mmmm>
We've noticed that it seems that the spines on the fin are starting to protrude now and the fin seems to be eroding.
<I see this>
I have included 2 pics of her from different angles (sorry about the clarity but she is a fast little sucker).
<Shorter exposures if you can... 125th of a second... with strobe/flash>
I was just wondering if you might be able to identify it and
suggest care/treatment for whatever it is that is going on?
<Root cause here is very likely either environmental, nutritional or both...>
Is this something that would repair/regenerate itself?
<With good care/water quality, and feeding, yes>
I have been checking water param.s daily (instead of my usual every other day) for the past 4-5 days and they are all perfect.
<... need data, not subjective evaluations>
She swims a ton and has been eating like a pig, so it does not seem to be affecting her in that way. Nevertheless, I wanted to correct this if there is something I can do.
As always, thanks again for the fantastic site, your help, and your time.

Re: Fin Rot? HLLE?  -02/20/08
Mr. Fenner,
<Mike>
Thank you for the quick response. Sorry, the water parameters are: ph 8.3, ammonia 0, nitrites 0, nitrates reading between 5-10, salinity 1.024 and water temp at 78 degrees.
<Mmm, these are all fine...>
As far as nutrition, I have been feeding spectrum marine pellets (1mm) in the morning, and frozen brine shrimp and bloodworms at night.
<And this is excellent as well...>
I will get to reading. Thanks again.
Mike P.
<I have seen such cases as yours... permanently erect unpaired fins, hard/fin spines poking through... in tangs, other fishes... Most of the times/instances, these do heal of their own accord... in weeks periods typically. Thank you for the follow-up. BobF>

 

African Yellow Belly Tang with large bump  2/14/08
We're having a bit of a problem with our African Yellow Belly (Regal) Tang. We've had him in our tank for about 14 months (that was well established when we added him). He's eaten like a champ from the beginning (formula two, seaweed clips, brine and mysis, clam, Spirulina, garlic, a liquid supplement to soak food in, and another frozen product that is made up of healthy "greens" that we mix with the meaty fare).
He had a bad outbreak of ich, which we treated with a freshwater dip and No-Sick Fish, product worked immediately, but he has developed a single large bump on his forehead, that seemed to pop-up overnight. I thought it might be from the ich, but it is blue (skin tone) and protrudes like a unicorn's horn, just below his top fins.
He seems to have recovered from the ich, his color is coming back rapidly, now this!
<The bump?>
The water quality is excellent, we've done several water changes and have been very careful in monitoring our prize fish. He does seem to be more timid than usual, I have attributed this to the ich outbreak, your thoughts?
<Perhaps the treatment... though NSF does not list ingredients>
Nitrates, Ammonia, etc. are at undetectable levels, temp. is holding steady at 80 degrees, ph. is steady as well.
Any idea what this could be? I've browsed WWM, RC and contacted several LFS's and still have no idea what to do. Please Help!
Thanks!
Kyel
<Maybe a tumorous growth of some kind, perhaps the expression of an embedded parasite... Necropsying the bump area... sectioning, staining, looking under a scope... is about the only means of being sure here. I would not treat for this mass. Bob Fenner>

Sick Regal Tang 02/08/2008
Hi,
<<Hello, Andrew today>>
I have a very sick looking Regal Tang who looks like he is about to pass away. Two days ago he stopped eating, and coming out of his hiding place in the live rock. At times he just falls against the glass and stops moving his fins and tail altogether.
The tank is two years old and at present houses only the Regal Tang (about 4") a Yellow tang (about 3") and one green Chromis, several corals , snails and hermit crabs.
I am trying to restock the tank and 2 weeks ago introduced a group of 7 Green Chromis (quarantined for 2 weeks prior to introduction), however one by one the Chromis have disappeared until only one (the smallest fish, but biggest bully) is left. We managed to remove one of the bodies but the others have not been visible in the tank, or we have seen then being eaten by the crabs. Someone did ask if we have a mantis shrimp in the tank which was eating the Chromis but I am pretty sure it is just down to the bullying nature of that fish that the others have died.
<<My initial thoughts did also lean towards a mantis hiding in there. Any clicking emanating from the tank??>>
I did a 20% water change last week, because of all the dead bodies, and the protein skimmer is working well. All the water measurements seem OK Nitrite 0.05, Nitrate 10, Ammonia zero and Phosphate zero. The tank is 4 x 2 x 2.
I have moved the regal tang into quarantine but don't know how to proceed, he has no obvious signs of any problem except complete lethargy. I have been feeding mysis shrimp, algae sheets and fresh algae, lobster eggs for the Chromis and a bit of flake but he will no longer eat anything.
Is there anything I can do?
<<Is the tang slow breathing? This is usually coupled together lethargy. For the most part, not overlit good signs. It could well be that the tang is suffering from a parasitic disease like Amyloodinium or Crypto, but is not yet showing the external signs of suffering. As its now moved to quarantine, I would suggest you keep a very close eye on the fish for any outward showing signs. continue trying to feed its favourite feeds, provide plenty of greens, with a touch of garlic or Selcon. Keep a good water change routine on the qt tank. Don't get dis-heartened about it. Also, what is the SG of the tank out of interest??>>
For his sake I would appreciate some help.
Caroline Reid
<<Thanks for the questions, hope this helps. A Nixon>>

Re: Sick Regal Tang 02/08/2008
Thank you very much for your response Andrew
<<Hello again Caroline>>
SG is 1.022, and he is breathing very very slowly if hardly at all.
Am going to pop out to LFS now for some garlic. Is there anything I can do to control parasites (will check the FAQ's now)? And is the Yellow tang likely to come down with it also - there is a UV steriliser on the main tank.
<< You could raise your Sg more towards 1.025..The best course is as in previous email. Monitor the fish for any external changes, keep a good feed regime and water changes. And most of all, stay positive>>
No there are no clicking sounds from the tank but with all the sounds of the water it is difficult to hear anything else. I am currently preparing water for a 25% water change of Q tank.
Caroline
<<Good Luck Caroline, hope all turns out well. A Nixon>>

Blue tang itching  1/23/08
Hello Crew,
I have a question about my 1 inch Blue Tang.
<Small...>
I have thoroughly read your pages on fish, diseases and parasites, and I am still not sure if my tang has ich, or if it may be stress.
<Perhaps a bit of both...>
I have had the tang in the main tank for 2 weeks. I QT him for 6 weeks before the move to the main tank.
<Ah, good>
He was in the main tank for 2 days, and began rubbing his belly against the rocks. He stopped rubbing his belly after three days, and had a few scratches from doing this, there was no injury, and no cysts have appeared. He seemed to be over whatever was bothering him. Three days after he stopped the belly rub, he started a head rub, and this has been happening for three days now, there are still no cysts to be seen anywhere on his body.
<Paracanthurus do scratch quite a lot... naturally>
He is breathing normally, eating, playing (he's hilarious), schooling with the chromis, and generally having a good time,
<Ahh!>
he has also made a bed in one of the sinularia. No other fish are showing any signs of itching, rubbing, scratching or cysts/spots. I haven't done anything to treat him yet as I wanted another opinion on whether it is ich or not. I asked the LFS, and of course they wanted to sell me a $50 bottle of liquid that is reef safe, and can be dumped into the main tank -
<Mmm, I would NOT do this>
they were not very happy when I told them that was one of the worst things they could recommend as a treatment. I stopped short of telling them to read WWW.
<Please, don't feel, be so reserved>
Should I just go ahead and QT, dip etc, or wait a few more days to see if those darn cysts appear?
<I would leave all as is presently>
It is going to be a challenge to catch him since he is only an inch, and I don't want to stress him if he doesn't have ich, and he just stressed.
Tank stats for your info are: 50gallon tank with a Fluval 305 canister filter (bio and carbon that is changed weekly), Aqua C Remora skimmer (best purchase I ever made), powerheads to blow the water around, T5HO lights, with live rock, aragonite substrate, 2 Sinularia, 1 BTA, cluster Duncanopsammia, cluster candy cane, cluster of Blastomussa (all corals are very happy). 1 ocellaris (hosting in the BTA), 1 mandarin, 1 bicolour blenny, 4 schooling blue/green chromis, and the tang. I know the tank is too small for the tang, he will be moved to a bigger tank. Water parameters are within the recommended limits (didn't list them as I have rambled on too much already).
Thanks for the advice, very much appreciated, my tank couldn't live without you :)
<Welcome! Bob Fenner>

Blue Hippo Tang Question 1/17/08
Hi Crew,
<Dane>
I am new to the world of marine aquariums but have been immersing myself in the literature this past month (including CMA - a fantastic book.) Anyhow, I got a great deal on a complete 55g setup with everything included, the tank is cycled with all water parameters in order. At the same time I purchased and set up a QT, and a week ago I purchased my first fish: 2 false perculas and a blue hippo tang. My question pertains to this tang:
When she (I'm just using she for ease of expression as I don't want to call her "it") first arrived she spent a lot of time hiding which I found out was very normal. For the past week though she's started roaming the tank a bit more, especially when she thinks I'm not looking. She's also been eating garlic-soaked Nori and picking at the clowns' flake food. However, today I got home and she seemed paler than usual. I also noticed that she appeared not have touched her Nori (it's normally all gone from the clip by the time I get home.) She was also very subdued. Water quality was all fine.
Nevertheless I still did my daily water change using water from the display tank. Have just checked and water from both tanks is good: Amm: 0, Nitrite 0, Nitrate 0, PH 8.4 (a little high I know.)
<Is fine>
So my problem seems to be that she's not eating and is now swimming around the tank a lot following her reflection.
<May be a clue here... I would darken an end panel (place a piece of paper over the outside) to rid this reflection>
Also, the paleness seems to be an issue and her breathing is rapid. It just seems like a big change from how she's been acting this past week.
Am I being paranoid?
<Mmm, no. Just observant and cautious>
I've included a few pics I just took to see if that helps you at all. (Just the fact I can even get near enough to the tank to photograph her is weird - normally she'd go and hide even if I walked past!)
Thanks for your help. I've been using this site everyday to answer questions I have and to supplement what I've gleaned from books. It is such a valuable resource to have. Keep up the good work!!
All the best,
Dane
<I take it you've already read re Paracanthurus on WWM... but please do review here re feeding: http://wetwebmedia.com/paracfdgfaqs.htm
I would expand the food selection and try soaking in a food stimulant (e.g. Selco/n), ahead of offering... and be patient. Bob Fenner>

 

Hippo Tang with recurrent Crypt  1/16/08
Dear WWM crew,
Thank you for receiving my question!
<Welcome>
I have a hippo tang (have had for 18 months) who I treated 1 year ago for Crypt.
<Looks like with copper... resultant in the obvious neuromast destruction here (HLLE)>
He successfully had 2 weeks of copper, other fish quarantined and display tank fallowed for 7 weeks. Despite all of this, he intermittently “breaks out” when stressed (change in environment, power outage etc). Has 1 mm “white spots” for 2 – 3 days, then they appear to cycle off and he appears clinically “free”.
<Mmm, yes... not atypical... Your system is infested still>
In between episodes he is lovely, with all other fish (2 pairs of clowns and 1 mandarin) unaffected. Display tank – 300 litres (80 gallon), these 6 fish and various soft corals. Sp gr 1025, temp 26C, pH 8.2, amm, nitrates, nitrites 0.
His last episode, he did not so readily recover from, actually stopped eating (amazing as he is always ravenous), and has since been returned to a treatment tank. He has been in copper (tested twice daily and maintained at 0.25 ppm – never below 0.2ppm) – he improved after a few days, then dramatically worsened and has remained covered. He has had 12 days of copper. I have started freshwater/methylene blue dips, which I think are giving some relief. He is slightly better than 7 days ago, but is still visibly covered with white raised 1 mm diameter spots – body and fins. Some are larger – up to 3 mm diameter, most are small.
<Okay... though the copper is killing this specimen... slowly>
He is in a 60 litre (13 gallon) bare bottom treatment tank - too small for him I know - am keeping ammonia down with 30 % water changes 2 - 3 times weekly, and occasional Chlor mon to neutralise the ammonia (your opinion on these products in this situation??)
<Can be useful>
His appetite is still great. RR is increased (approx 80/min) with open mouth.
My LFS says it is not Crypt but continue copper.
<... Is very likely Cryptocaryon... Do they have a scope?>
I am concerned with prolonged exposure to copper with this Tang, and also – what am I dealing with? I would value your input on this case. Continue copper? -
<I would not...>
how long until I should expect a response? How often should I freshwater dip?
<These won't cure the resident infestation...>
Should I try formalin dips?- how often?
<I wouldn't>
Should I skin scrape? (if so, how with a glass slide, and what should I stain with?
<H and E... or any other acid fast...>
Any good sites for protozoan ID?
<None that I know of... look for Ed Noga, "Fish Disease, Diagnosis and Treatment">
I think scraping would be very difficult/traumatic on my scatty hippo tang .. he is crazy…easily freaked out…).
<... you could try a quinine route of treatment... but returning the fish to the infested system...>
I have included some photos – difficult to capture, but they may be of help.
Myself and “Big Blue” are extremely grateful for your advise.
I often and extensively utilize your website, and am grateful for the knowledge, experience and wisdom found within it.
Thank you,
Kim Newell
<The best route (of a few) would be to cure the Paracanthurus... and place it elsewhere... and resist placing any new fishes in the infested system... Please read here: http://wetwebmedia.com/parasittkfaq2.htm

New Regal Tang, hlth.  01/14/2008
<<Hello, Andrew here>>
I work at my LFS, a few months ago our marine tanks where wrecked by some HBH balancing blocks, yet my idiot boss refuses to re-cycle the tanks, and even worse, still insists on ordering new fish (and selling them while they are entering the early stages of ich). Don't worry, one of us (me or her) will quit soon. Anyway my question rests with a 2-3 inch regal tang (which I've been wanting one for ages) who was ordered and placed in one of our wrecked tanks, it sat there for days hiding and sitting lethargically on it's side (to be expected) but it was doing it for longer than it should have taken it to settle in (it also flashed quite a lot, ich?).
<<Sounds precarious..>>
Against my better judgment I took it home as I knew it would die a certain death at work, it's currently sitting in my 50 litre quarantine with crushed shell and coral + one piece of (very healthy) liverock.
<<Remove the sand and rock from the quarantine, just have a piece of PVC pipe in there for hiding. Sand and rock can harbour parasites which will remain, and the idea of quarantine is to keep parasite free for new arrivals. Its also easier to clean after the quarantine process is complete>>
It seems to be improving (since I brought it home yesterday) but the shells + LR are probably the worst things it could possibly be flashing against. I tested the water with some tri-sulfa <<Would stop using this>> before drip acclimatizing it, although I know now that this probably won't help a lot. She eats like a machine (I've been feeding her some krill/Spirulina granules) but still scrapes and hides on it's side under the (bridge shaped) live rock most of the time.
<<Best advice is to keep a close eye on the fish, is it showing any signs of Ich? It does sound like Ich, however, I would not pre-empt a treatment until you can confirm this>>
The water param.s are (tested 3 days ago) :
PH:8.2, Ammo: 0, Nitrite: 0, Nitrate: 0, SG: 1.023-5
Once she is better I plan on putting her in a 55gal with 1 royal dotty back, 2 false Perculas, one green Chromis and a coral goby (suitable tank mates?).
<<Suitable tank mates, however unsuitable tank size, you ideally need 120 or more gallons to house these fish. Yes, its small now, but these do grow quite quickly in a well maintained system>>
Anyway my question is, is there else anything I can be doing (or doing better) to ensure her good health and survival?
<<You're taking the right approach with the fish. Keep it fed well on a good staple diet, maintain excellent water parameter and keep a very close eye out for Ich. Hope all goes well with the Tang>>
Thanks, Oscar.
<<Thanks for the questions, A Nixon>>

White patch on Blue Tang (Paracanthurus)    11/30/07
Hello WWM crew...
I have a blue hippo tang with white patches all over it's body (I have included pics).
<I see these>
This has happened on two occasions. The fist time, it wasn't that bad, and In asking advice from aquariacentral.com.. they suggested that the cause was the tang not getting enough green's in it's diet.
<Mmm, maybe... not the greens per se though>
I then fed it greens, and it went away within a few days. Now, just a few weeks later, it has happened again, except this time it is a lot worse. I again went to AquariaCentral and they suggested that it is stress (caused by possibly the damsel).
<Possibly a component as well>
I have a very tame damsel, and it never bothers the tang, however occasionally I will see the tang chase it around, however it has always done that. (5 month old tank) Here is the thread on AquariaCentral regarding my problem: http://www.aquariacentral.com/forums/showthread.php?t=131877
Tank Specs:
55 Gallon,
<This species, Paracanthurus, needs more room than this...>
1 Blue Damsel, 1 Blue Hippo Tang, 1 Yellow Watchman Goby, 1 Hi-fin Goby, 1 Banggai Cardinal, 2 Scarlet Skunk Cleaner Shrimp, 3 Sexy Anemone Shrimp, 1 Sand Sifting Sea Star, 1 Serpent Sea Star, 1 Brittle Sea Star,
<What species? If Ophiarachna in particular, this animal could be over-stressing the Paracanthurus by night>
various crabs/snails for a clean up crew
Water parameters are all fine (0 Ammonia/0 Nitrite/ 15-20 Nitrate).
<This is borderline... too high... another source of stress... the real "cause" here>
Do you believe that it is stress that is causing the tang to produce these white patches?
<Yes>
Currently the patches are starting to fade, however I wish to try to prevent this problem from happening again...
Thank You!
-Jessica
<This is a "good" email in that you've provided most all the useful, pertinent info... A few "things" would help here... A larger system, the addition of a living sump (refugium), the culture of macroalgae there and its feeding to the tang, perhaps the addition of "mud"... This is a HUGE amount of material to introduce to you... not knowing what you already are aware of. Please take the time to peruse here: http://wetwebmedia.com/marsetupindex2.htm
