Some kind of snail?

[corwise]

Hey folks,

I recently noticed a few of these things crawling around my rocks. Not the best pic, but best I could do. They look like little snails, with at flatish shell that looks to small for their entire body. The biggest one I've seen is about half an inch long, several smaller ones. Anyone have an idea of what they are, good/bad? Also, since I finally took a good pic, I'm posting a pic of my Sebea clown and the leather he's hosting in.
