What is this?? A slug? A snail?

I just took it out of my tank. It looks kinda like a snail, but it's like it's shell is disolving off of him, there is only a very tiny area of shell on top. It is super fast, I could hardly get a godd picture, much faster than the turbo snail which are about the same size.

stomatella perfectly harmless and a great free cleanup crew addition. I have dozens and dozens of them. Cheaper then snails! they breed regularly.

It's a stometella. (Snail) It is a good hitchhiker.

Stomatella

They are correct, stomatella . They're actually pretty neat creatures to watch. Only thing is that I find that they're nocturnal so you dont see them out and about during the day. Good at cleaning the glass.
