Tiny snails on Zoas (need ID)

[Mikec805]

Found 2 of these on my Scrambled Egg zoa frag, which have been closing up and just not looking that great for the past couple weeks (since day one to be honest). Compared to the rest of my zoas which have been popping out new heads and looking great. Anyone know what these are?

looks like a collonista snail. It shouldn't hurt anything. They just eat algae.

Might want to get a pic of the zoa in question, and ask in the zoa forums. They might be able to give you an idea on whats wrong with your Scrambled eggs.
