Can you ID what these shells belong to?

I have found several of these shells on the sand bed over the last few weeks. Anyone know what critter they’re from?

Stomatella snails, good guys. But, the fact that you're finding the shells might mean there's a predator? What do you have for livestock in your tank? Fish, inverts, etc
It could be that you had a lot and a few have perished over time?

Cool, thanks for the response. I have 3 tangs, 2 blennys, 2 clownfish, sixline wrasse, spleandid dottyback, sifting star fish, astraea snails, one dwarf zebra hermit crab. If I had to pick the culprit it would probably be the dottyback or the hermit. Ive had the hermit about 2 years now and its grown a decent size. It’s also killed a few snails.

The sixline will make a meal outta them as well...

Yeah. Sixlines will eat just about any small mobile invert.
