Looks like a harmless stomatella snail.

What they said ^ . I have several in my system, the breed prolifically, can get into and clean smaller crevices than any of my other snails, and feed my corals as pictured; overall they're pretty darn beneficial little buggers!

I actually never bought one. It was a hitchhiker

Sometimes you'll see them spawn! Great coral food!! They'll do it simultaneously!
