I only see him at night on the glass I didn’t put him in my tank he just showed up I used dry rock when I set up my system and I dip all my corals before adding them I just learned about QT corals i Think there’s more then one it looks like a snail with no shell and I wanted to know if it’s a pest thanks

Stomatella snail. Very good CUC

+1 in stomella. To me , always a mystery. We all acquire them sooner or later but yet you can’t buy them in a pet store yet they keep the glass clean.
