Lost 4 fish in past 2 weeks!!

bkhunt · Apr 22, 2013

no never even thought or hear of doing that. it also just seems funny that it was all of my bigger fish (2 tangs and angel). the clowns, 6 line and ornate wrasse are fine, and other large chromis are fine. Also has not affected the tang that is hanging out in my sump until I get him a new home. What can I treat tank with that is reef safe?

Heard Prazipro is reef safe. I have only used it in my QT tank though so I don't have first hand experience when it comes to corals' reactions to it.

BK did you by any chance do a water change recently,if you did what salt did you use.
The reason for my question is, at the end of December I did a water change and a day or so later lost a whole bunch of fish,these are fish that I had for a long time.About 5-6 weeks ago I did a water change, I had quite a few fish in the tank that had been in quarantine tank for 3 weeks before being added to the tank,these were all healthy and eating well.Then started to die off.Checked water etc and the only thing that I did was change water.I have no idea if the salt has anything to do with it.The four fish that remained were and are still doing well.

Why yes I did use a new salt. I used the salt that I had won in a contest here at R2R. I did a water change a few days prior to the first deaths and did one more using that salt. I have gone back to my RC and no problems or deaths.

So I thought I was doing good no fish loss in the past few weeks. Just found a 3 inch chromis dead and it was alive last night at midnight when I was looking in tank with flash light. Same thing it was all chewed up by its vent with the guts, gills and eyes gone. I did not see anything on, in or near the body of the fish.

I am so at a loss as to what is killing all my fish and eating their insides. I am looking for and and all suggestions. The tank has been up for over 2 years and I am the second owner.

I have not added and rock to the tank in the little over a year that I have owned it. If it was a mantis I think I would have seen it by now. Short of taking all rock out and letting it dry out I do not know what to do.

I do have 2 cleaner shrimp and a peppermint shrimp and a sand sifting star in the tank at my only inverts. Fish include 4" Ornate Wrasse, 6 Line Wrasse, 2 True Perculas and now 2 Chromis and a Atlantic Blue Tang in my sump who was being punished for harassing other fish. Glad he is still in the sump now. I also have a lot of corals and 5 RBTA. HELP!!!

I would put some type of trap baited with food in the tank at night to see what goes into it.

46gReef · May 21, 2013

That's a good idea...you never know what you may catch...... I wouldn't look too much into how you find them after their dead to be honest. There are so many animals in our reef tanks that will capitalize on a dead fish, I would bet money that how your finding them(eyes gone,insides eaten out, etc.) is not what caused their death. How old are your test kits? Can you take a H2O sample to a LFS for testing? What type of corals do you have in your tank? Anyway something's getting into the tank chemical wise? Air fresheners/carpet cleaners/perfumes or colognes of any type? Anyone put their hands in the tank that apply skin lotion? Just thinking outside the box here.....

set a pop bottle trap with some Mysis. Forgot I got a few of these several months ago and have not seen in a while. Was told the were chestnut nassarius. If anybody can give a positive ID that would be great. the are about the size of a ping pong ball.

46gReef · May 21, 2013

I don't think their nassarius, I remember seeing these before at my LFS......I can't remember what they were though....gimme a few, it may come to me!

bkhunt · May 21, 2013

Test kits are about a year old. Corals in my tank are about 40 types of Zoa/Play and some LPS. I have 5 RBTA. I am the only person who put an are in my tank and I use no lotion. Clean glass with RO water and a paper towel.

46gReef · May 21, 2013

I was wrong, just found a pic on aquacon.com that says their orange spotted nassarius

46gReef · May 21, 2013

Any chance 1 of the nems got em? I lost a wrasse to one of mine once....

eliramos · May 21, 2013

The nasarius is definitely the culprit of the Wierd carcasses...as to what's killing everything? Very strange...and it's only larger fish? Very odd.

I would agree, I don't think there's a nassarius out there that could/would pass up a free meal.....

eliramos · May 21, 2013

I feel like it's going to be an obvious answer lol have you been supplementing anything, changes in food, did your tangs have wierd blotches on them before they died?

Ok I put in a pop bottle trap. This morning when I got home from work I went to see if I caught anything. Well nothing in the trap but I did see an possibly orange/pink something that was so fast I could not make anything out of even see where it went.

I have not changed anything in my tank except for using a new salt for two water changes.

That is my biggest thing is that it is all of my large fish and expensive fish. I do not think it is any of the anemones as they do not even eat mysis, krill or silversides. I have tried to feed them but they just let it go after a minute or so there for I gave up feeding them.

Thanks all for you suggestions and help. Hope to solve this problem soon as I would like to restock my tank. My LFS is holding a fish for me until solve this issue.
