Help! Unknown zoa killer!!!!

[tylerwalker]

It started with some green zoa got home from work and half the rock looked like you took a knife and just leveled them you can see the small circles, other half just fine. Next day all gone. So I thought the one spot foxface could be it being it is an herbivore. Then couple days later the blue,orange, and others. I have no clue what is eating them or what's going on? never seen anything on them night or day. I have a foxface, two clowns, two damsiles, mandrin goby, cleaner shrimp, two pepperment shrimp, 20 or so snails, same with herments red and blue leg, one orange leg.

Did you acclimate properly? I did the same thing and luckily the parts that came off the rock formed on another piece. So look out for those zoas!

foxface, pepperment shrimp both are a maybe i would water the zoa's more closely later night early moring while the lights are out and check for sun dial snails and spiders.
