Zoos dieing off.

[jh2pizza]

I have zoos that have been in my tank for 3-4 years , they died off and left was this orange covering on the rock. Didn't thing much of it, but now other zoos are fading away and sure enough, there is the same orange coloration on that Rock as well.

Any ideas?

Sounds like a possible fungal infection to me. Do you have a QT tank? You might want to check out the zoanthid forum for help with this problem.
