Tylomelania gemmifera
A large freshwater snail with a tall spiral shell and a rabbit-like face, endemic to the lakes of Sulawesi. It is ovoviviparous, bearing shelled young one at a time.
Tylomelania gemmifera belongs to a genus of freshwater snails endemic to Sulawesi in Indonesia. The genus is almost restricted to Lake Poso and the Malili lake system, which includes Matano and Towuti, and is said to be unable to live much above 700m. Thirty-four species were described by 2005, and von Rintelen and colleagues added fifteen more between 2003 and 2008. The tall spiral shells vary widely in form and colour and the aperture closes with a calcareous operculum. The snails are gonochoric and ovoviviparous, females bearing young that already have shells and can reach 2cm, among the largest newborns of any freshwater snail. The radula varies greatly with diet and substrate, which lets several species share one habitat by partitioning niches. It lives over substrates from sand and mud to rock and sunken wood, and its thick shell is read as an adaptation to predation by the crabs of these lakes.

It uses substrates from sand through rock to sunken wood, so combine a fine sand it can burrow into with stone and driftwood where algae grow. It is a large snail that eats a good deal, so allow a generous water volume.
It is endemic to the lakes of Sulawesi and is a lowland snail absent above about 700m. Avoid strongly acidic water, which erodes the shell.
Peaceful and harmless to other animals. Do not house it with snail-eating fish or with assassin snails, and avoid fish that nip at tentacles. It sometimes eats the soft new growth of aquatic plants.
The genus has a radula that varies with diet and substrate, and the snail rasps algae and organic matter from the bottom. It is too large to live on tank algae alone, so give sinking foods and blanched vegetables regularly.
Gonochoric and ovoviviparous, bearing young that already carry a shell and can reach 2cm, among the largest newborns of any freshwater snail. Few are produced at a time and increase is very slow, so overpopulation is unlikely.
Several Tylomelania species are traded indiscriminately as rabbit snails, so the identity of a purchased animal is often uncertain. Never use copper-based fish medications, which are toxic to snails. It is not listed by CITES.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Rabbit Snail is 4-6 years. With proper care and nutrition, they can live a long and healthy life.
Rabbit Snail feeds on: Algae, biofilm, sinking prepared foods and blanched vegetables. Aim for a balanced diet with appropriate feeding frequency.
