hi

So I went camping for a night I got back tonight to find one on my electic yellows dead!!!. Water parameters were all fine. This is what I have in the tank its around 350litres roughly. 2 red zebras around 4cm long, 1 midnight peacock around 7cm long, 1 female peacock around 8cm long. And HAD 3 yellows around 5cm long ( I measured the dead one it was 5.2cm). Anyone got any ideas as to what happened. I am guessing someone killed it but there was no marks or nothing visibly wrong with it. Could it have been a possible fight between two males although like i said no marks were found on it.

It's impossible to say what happened without alot more information...

How long has this tank been set up?

What are the water parameters on the tank?

What is your normal tank maintenance routine?

Was someone else feeding them in your absence?

Have you lost any other fish recently for unknown reasons?

Added any new fish without quarantining them?

hi

The tank has been set up for about 2-3months. I got the peacocks about 3 weeks ago I only got the zebras and yellows 1 week ago. Water parameters I measured were, ammonia =0, nitrite = 0 pH 7.7. My normal tank maintenance routine is just a 50% water exchange every week. the fish were not fed when i was away. All fish are added without quarantining them. one of my rainbow fish was also dead.

It could be "new tank syndrome", or it could be that you introduced some sort of disease with the new fish.

I would just keep a very close eye on things for awhile. Should you see any of the fish behaving differently, post back wtih the symptoms and we'll try to help.

The red zebras aren't pairing fish, they are harem breeders, and are going to be way too boisterous for the peacocks long term. They can also crossbreed with your yellow labs, so there may be some extra intensity in the aggression towards them.

Stocking choices can always play a part in the health and welfare of your fish.

hi cichlidaholic

thanks for the advice. Unfortunately i just got home from work to find another of my yellow labs dead. Im guessing it must have been a disease because a relation of mine brought one from the same tank and his was sick yesterday I havent heard if it died overnight. I cant see any symptoms the remaining yellow is has a white sheen on it thats the only thing I can see thats different. I am just lost as to what i have done wrong.

thanks

Is the "white sheen" cottony or fuzzy in appearance?

Any unusual behaviour from the fish? Are they twitchy? Flashing against objects in the tank?

You could be dealing with a bacterial infection. If so, it may spread to your other fish.

hi

Nar its a was a white almost like it wasnt a proper yellow however the remaining yellow seems to have got more "yellow". i have seen them rub themselves on the gravel a few times. the remaining yellow hasnt died so I will just see what happens over the next few days and report if anything else happens.

cheers

hi

Well im absoultely disgusted all my yellows are now dead. The only sign is they stop eating a day before they die. can these fish get bloat from normal cichlid pellets? Are yellows a lot weaker then other cichlids? i dont think i will bother with them anymore.

thanks

My labs are the most hearty of all my fish. Its not the species. Sounds like you got a sick batch that killed them off one by one. I'd keep a close eye on my other fish if I was you, just to make sure they don't catch what your labs had.
