Help ID this snail? Slug?

[Fcamdog]

Very hard to see in the pic so read description a few times. Looked a lot like a snail would out of it's shell. Was white, I could see it eating off of the liverock. I thought I could make out some little tentacles like a snail as well. (Honestly, I'm not 100% sure on that last one.)

If you have any ideas, please share.

P.S. Look at 4-5 O'clock, referenced from the zoas on a frag plug.

looks like a Stomatellid snail to me. Harmless algea grazer. Do a google search and see if that is it.

abit hard to tell from the picture but i would agree it looks like a stomatella from that picture. they are harmless and do a great job cleaning up your tank. here is a link to the stomatella snail so you have an idea what they look like.
