Zoas Killed my fish

[wrgoff]

I recently added 7 new Zoas (WorldWideCorals) to my 240 Gallon tank. In less than a week, all my fish died. Funny thing is all my invertebrates are fine. So are my anemones are fine as well.. Just all my fish are dead (2 Clowns, 1 Wrasse, 1 Tang, 6 damsels). I tested my water, all params look fine. Has anyone else seen this?

I'm going to venture that no one has seen this, meaning zoas or palys being the cause of mass fish death. Especially in a tank with so much water volume.

Odds are you had a very fast acting disease rip through your fish population, and didn't notice until it was too late.

I have never heard of zoas killing fish before. Like Rjukan said, you probably had a disease that killed off your fish. Did your fish show any signs of stress, or have a change in appearance recently?

Zoas didn't kill your fish

Did you dip the zoas by chance?

Its possible but highly unlikely that the zoas brought in a fish disease like velvet or something like that. I would not expect that from wwc at all. The zoas themselves didnt do it no matter how toxic they are or are not. How long have you had the fish and when was the last fish added?
