tiny snail id?

[phish7740]

so i reciently found a bunch of these tiny snails. i counted about 30-40 mostly on the sand. but also on the glass, rock, zoos.

discription: they are brownish/white in color some darker than others. the shell is long in shape, looks like the shells the small hermit crabs are in. the "foot" is white with two small "anteni"

they look like tiny snails basicly. i have not seen any snail eggs, nor do i know what snail eggs look like

sorry the pics are terible...they things are about 1-2mm in size. and i cant get a good pic.

so are these just snail babies or harmfull hichhikers that need to be removed.

thanks

Gosh, the pics are so tiny, it's hard to tell. They could be baby cerith snails. If so, they are a good addition to the tank.
