Mysterious Death(s)

[dhoch]

I came home from work today to find my eel (chain link) 3+ years old and over 30" long dead in the front of my tank. No injury, nothing seemed wrong with him.

He last ate 2 days ago (allthough he would only feed 2-3 times/week, so this was not unusal).

This is the 3rd of my oldest fish that just seem to die no explination. One night swiming fine, next morning not looking good, dead by afternoon. It happened with my yellow tailed damsel, then my blue devil damsel, now my eel (allthough he is not my oldest fish currently, it's my naso tang).

Tank params are fine:
Temp ~79.3
PO4 0
NO3 2.5
NO2 0
AM 0
Cal 410
Alk 9.9
pH 8.3 (right now, with an 8.1-8.3 swing AM/PM)

I feed (to my fish) a mixture of pellets, flake and frozen prepared as well as some fresh/frozen seafood (mussels, and shrimp and silversides)...

The eel only late the fresh/frozen seafood (typically shrimp/mussels/silversides).

Any ideas?

Maybe he/they got a parasite from a new fish or from some fish food or something?

Maybe one of them always had a parasite and for some reason suddenly succumbed to it & the parasite reproduced & moved on to the others?

Sorry about your losses..

Bump-- at least

that is strange, I can only think some sort of cryptic organism that made it in on one of your animals. I hate posts like this, everything checks out and seems fine,but fish keep dying.
makes one feel helpless.
how many fish are left in the tank? perhaps if it were allowed to run fishless for several months whatever is killing your fish will die off.

Sorry to here about your lost. My yellow tang that has been with me for a year and a half died two days ago too and I'm still trying to figure out why.

There may be some type of disease floating around... It makes me nervous to think that... I hate when any of my creatures die.
