[Darylb]

hey guys just got some new zoas havent opened up yet but there was a snail on it that is now eating the algae in.my tank is it good or bad also got this other coral would like an id on it too i know i got cyano but im dealing with it now

The coral looks like galexea. Can't tell what kind of snail it is, does it have a siphon sticking up? I'd say it's good if it's eating Cyanobacteria.

Duncans, hairy mushroom and can't tell which snail you got.
