Does anyone know what snails these are?

These snails suddenly appeared in my tank months after adding live rock. Anyone possibly know what sp these are?

It's hard to tell as it's so small, might be a cerith or nassarius snail if it gets larger. Where did the live rock come from? Knowing the collection area might help point to a species.

like @saltwaterfish.com its pretty hard to tell and is probably a baby, maybe a fat dove snail?
