Why Trapdoor Snails in Ponds? We know snails in ponds (and aquaria) help remove excess foods and any undetected dead stuff they can reach. Snails will eat stuff nothing else will touch — like moldy old fish food. Maybe not the best diet for them, but they help prevent the overfeeding syndrome so common with new aquarists/pond keepers.The biggest difference between these guys and mysteries and apples is their lack of a lung. They never run up a snorkel to suck O2 from the air. These means they do not drown when ice covers their water — a recurring problem in our neck of the corn belt buckle. Better yet, since they suck no air, cool weather won’t kill them.They are breed-able and it is easy to distinguish sexes. Original Origin: Japan
