Well it happened again.....and yet again*updated*

It's definitly not the zoanthids that killed all your fishes and CUC. It must have been something else. Probably one fish died and produced ammonia that killed the rest. It happens all the time without zoanthids and if you had fishes in a 10 gallons tank, that was calling for trouble from day one.

Dunno how many fish you had in there. My frag tank is 20 gallons and I had a mandarin in there for 4 months without any problem, then I had a damsel and no problem either. I put all sort of zoa and paly in there and they slime a lot after I frag them but never killed anything and never noticed the slightest thing wrong.

Fish dead, bristle worms all hanging out of rocks and dead, large feather duster worm dead, inverts all dead, hairy hitchiker crab I was trying to catch for a few weeks dead, pretty much everything except for the slimy zoos.

It is definately the zoos that did it. In a larger system I am sure it wouldnt have happened but I didnt think and put 30 or so of those zoos in my 10 gallon.

Maybe they all reacted at once for some reason in your tank and released the slime.
