Unsure if friend or foe

[NewReeferKev]

Found this thing on my rock today. Resembles a snail with no shell kind of. Any advice what to do with it would be great. Is it a friend or a devil?

Looks like a stomatella snail. Cool little guys.

Friend. Stomata snail, just an algae grazer.

Thanks for the replies! No idea where he came from. If harmless, it can live to see many happy days

They come off of rock and coral. Good find considering that is the only way to get them and they aren’t too common.
