i am breeding snails in a small plastic tank.
i tried them without a heater to star with but they wouldnt breed, once i added a spare heater the babies started arriving. I also have a small air pump powered filter in there to keep the water circulating and stop the water fromn going stagnant and stinky. i put in any uneaten leftovers from my other tanks, flakes, old plant leaves that come off, and plants cuttings. the more food, the more snails....
