This is going to depend on what is actually wrong with the snail.
If you are seeing signs of shell deterioration, this is being caused by either a lack of calcium in the water, or your PH is too low (acidic), or a combination of both. Make sure that your PH is not acidic, and that you have a source of calcium in the tank such as simply adding some cuttlebone to the tank.

it must have mated with another snail at the hatchery or pet store. Mystery snails (Pomacea bridgesii),like many other speciese of aquatic snails, can hold the sperm from mating and fertilize the eggs that are still in the snail.
The Mystery Snail will crawl out of The tank and bite you, so get some gloves or something so it does not get slime on you.
