ID on small snail W/ good pic

[bobbyblank]

Hey everyone. I a ton of very small snails roaming around my tank. Most end up food for my dwarf hermits since they are size of a number on a credit card. There are lots of them, but i have only seen a handfull of this color and shape. I havent seen them bothering anything yet, just want an ID before problems pop up. Thanks
