It is a pond/bladder snail. Often called pet snails. Nerite do not breed in freshwater so I am sure it is not one.
If you do not overfeed, these snails should not reproduce out of control. At least that's when I had an overpopulation occur.
Whatever you do, though, do not turn it loose in a pond or stream or flush. It is better to throw these snails out in the yard to feed other critters.
