I bought something called "Black mystery snail" at Petsmart, which was most likely some kind of applesnail. The snail bred relatively easy - one day there was a clutch of eggs hanging above the surface of the water. Since that was the only snail in the tank, I assume that it was pregnant when it left the store. It can carry semen for quite a few weeks, so I heard....

They can actually store semen for a couple months!
