Snail Identification

Can anyone Identify this snail. I currently have about 20 of these in various sizes. The picture is of one of the larger ones. The baby snail's are all over the glass, sand and rock.

Could possibly be an tiny Astrea snail. However, getting a closer picture would help to identify it for sure.
