Snail ID'S pls

[Shobloth]

Found these 3 lurking after lights were out.
What are they and are they bad for a reef or clams?

Two Stomatella snails and a Columbellid snail perhaps? (harmless)

The two with little shells are stomatellas. They're harmless. I don't know what the third is.

Good job, Cloak.
