ID slug? shell-less snail?

[scubagirl12]

I have seen then in my tank for a few months now but very rarely. Tonight it was out on the back wall so I ran to get my camera. It looks just like a snail but no shell. There is a small flat hard piece on half of its back though.

Most likely a stomatella snail.... not usually a problem.
