Did a snail lose it's shell? He's actually crazy fast too! I think I will name it Winston. Or should I kill it?

Looks like a Stomatella Snail.

Looks like a Stomatella Snail.

+1 have those in my tank. Mine just have a darker shell.

Definitely a stomatella. Harmless, algae grazing hitchhiker.

Thanks. Had me a bit stumped. It looks as if there is no shell. Fast too.
