Sump friend or foe?

Gazing into my sump and I see this tan and brown shell looking thing. Snail baby? Doesn't look like any of the snails I have though.

Pyramid in shape and shell building pattern on it

Interesting how I haven't added anything in terms of coral since December and is has popped up unexpectedly. Added 1 angel Japanese wantabi I think it's called.

Can fish carry them I wonder?
