Most LFS won't take them until they are about nickel sized, which takes some time. If you are going to hatch them, I would recommend hatching them into a breeder trap so that you can move them easily to a grow out tank once they hit pea-sized. Keeping them in a breeder trap makesit easy for them to get food and for you tomaintain the tank. Please remember each clutch can produce anywhere from 50-200 snails, so before you hatch them confirm wiht your LFS they would want that many.
