what happened?

Hi,

Part of the problem is when you find a dead fish, and not see it die...the CUC does more damage, they often begin feeding before the poor fish is even completely dead. That makes it look like torn fins and bite areas (signs of aggression). I think this is going to remain a mystery death. Smaller fish do kill larger ones, so the battle could have been between the two that died, and the CUC made the wounds look larger, ich kills even if you don't see the spots (it's still there, just at a different stage) and some fish do just stay stressed out, and die from that... so it could be anything. Give things a month or so before replacing the loss...just to be sure all is fine, keep a close eye on your other fish. If you don't see any signs of aggression, or illness...then replace one fish at a time.

I treated the achilles in a qt when he got ich so it isn't in my dt. I also don't have much of a clean up crew other than a turbo snail and chocolate chip starfish so the injuries were there before he died and if you can find a 1" hippo tang that kill a 4.5" Achilles tang then I'll believe it was aggression that killed these fish.

i see what you are saying maler. when did you find out they where dead? if it was agression you should havr seen them fight befor. but if it is a parasite. wouldent they have shown signs of it befor death?

I haven't seen them even look at each other since they were first introduced to each other. that's what I would think too but they acted normal until the morning that they died

A CC starfish can do plenty of damage to the dead, if you had a proper CUC, you may not have found any dead body at all. I never do, unless I find the dead first and remove it. Do like I said, and watch the other fish for the next month or so...if all is well, then replace the lost fish. I really don't think you are going to figure out what happened, sometimes it's just a mystery that never gets solved.
