Sounds like pond snails, if you can get a straight on picture I can say for sure.

toddnbecka said:Most snails are hermaphrodites (both m/f sex organs) and will lay eggs, but they still need 2 to reproduce. However, only having one snail is no guarantee, unless it has been the only snail in the tank since it hatched, because any given snail may already be fertile before being placed in a new tank.
