Snail id please

I found a couple of these little guys on a frag i just bought. Any idea what they are and are they good or bad?

Looks like a collonista snail maybe?

I think your right. Thanks.i dont think i am going to let them in the tank. From what i read they can become an infestation.

Personally i likr these lil guys. They can get in all the nooks and crannies thier larger cousins cant.
