The great pond snail is very hardy and can survive in a wide range of conditions. It is very easy to keep, although like most aquatic snails the great pond snails 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 and shrimp pellets or fishfood. The great pond snail is a hermaphrodite and very easy to breed and does not need any special care to do so. They lay long clumps of transparent jelly containing between 30 and 140 eggs at a time on glass, rocks and the underside of leaves. While it is a common beleif that snails will over populate your pond or aquarium this will only happen if if there is a massive surplus of uneaten food and can be a good indication of over feeding (for image of eggs see main pictures).
