Snail ID

[ReefJunkie]

I have no idea what type it is, but we have 2 in our tank, one is exactly the same as the one in your pic and the other is white with a black pattern on its shell. They started out tiny and are now about 1/2 an inch, neither bother anyone else and they seem to eat algae, they mostly stick to the glass or hide out in the macro algae. I think they may be a type of vegitarian whelk or something. I wouldn't mind knowing what they are though.

A Tulip Snail perhaps? (Family Fasciolariidae).
