Welcome to the freshwater snailpages,here you can find info on snails in the aquarium,freshwater snails in nature and a description of some species. Most people who have an aquarium have snails too.And some of them try very hard to get rid of them.It is true that snails can cause damage in aquariums by eating the plants.But snails can be an interesting part of it too.Especially Applesnails are very beautiful creatures and an enrichment to any aquarium. More about those snails later.Native species can be kept too,but can reproduce themselves very rapidly and some carry parasites. Freshwater snails are very similar to those on the land but there are some differences. Because they live in the water their breathing must be adapted to that.Some snailspecies have a fine maze of arteries in their tentacles,they function as a kind of gills. Freshwater snails have only one pair of tentacles,their eyes are placed on their head.
