yup looks very much like one... check all yours zoa's at night with a flash night..this is when we were able to see ours when we had them the easiest...

we even lost all of our small colonies because of them and fresh water dipping.. be careful, when doing this, dip but not too long...

We also purchased a green wraase and he help rid the tank of them

May look into the wrasse. Been wanting to add something else. Everything else in my tank has been great! Duncan is growing well along with the Kenya trees and green star polyps.

My red corris wrasse destroy snails, its almost impossible to keep any type of clean up crew. I have empty shells everywhere, but they make for good rubble or frag mount.
