malaysian trumpet snails (Melanoides tuberculata )
Bithynia tenticulata is hardy and can survive in a wide range of conditions and is very easy to keep, although like most aquatic snails it can be sensitive to acidic water (low ph). They can easily survive from scavenging and don't need any additional food especially if being kept in an outdoor pond, but if you want to put extra food in for them they can be fed algae wafers, bloodworm pellets, shrimp pellets or fishfood. Unlike larger snails with an operculum, bithynia lays eggs between 5 and 30 at a time on rocks and plants and is a fairly fast breeder.
