Rabbit Snail Care Guide - Aquarium Setup, Feeding & Breeding

Rabbit Snails are striking freshwater gastropods recognised by their long, conical shells and extended, rabbit-like snouts. Their shells may be brown, black, cream, yellow or patterned, while the soft body can range from golden yellow to dark brown, often with contrasting markings. Different Tylomelania species vary considerably in shell shape, colour and adult size.

These snails move steadily across surfaces with a broad muscular foot, using their rasping mouthparts to graze on algae, biofilm and soft organic growth. They are generally peaceful and spend much of their time exploring the substrate, wood, rocks and aquarium glass. They may become more active after the lights go out, although healthy individuals can also be seen during the day.

In the wild, Tylomelania inhabit warm, mineral-rich waters with rocky, sandy or muddy bottoms. Some species live in flowing streams, while others are associated with the deep and shallow margins of Sulawesi’s lakes. Their elongated shells and flexible bodies are well suited to investigating crevices and soft sediment.

Rabbit Snails are valued for their unusual appearance and useful scavenging behaviour, but they are not simply disposable algae eaters. They are living, breathing animals that require suitable water chemistry and a reliable food supply. Under good conditions they can become long-lived and rewarding inhabitants of a carefully maintained tropical aquarium.

Rabbit Snails are native to the freshwater lakes, rivers and streams of Sulawesi, Indonesia, in Southeast Asia. The name covers numerous Tylomelania species, many of which have highly localised ranges around Sulawesi’s ancient lake systems.

A minimum aquarium of about 75 litres is suitable for one or a small group of adult Rabbit Snails, with a footprint of roughly 60 cm by 30 cm or larger preferred over a tall, narrow tank. Use stable, well-filtered, oxygenated water with moderate to strong mineral content, and provide smooth sand or fine rounded gravel that will not damage their soft foot. Add rocks, driftwood and hardy plants to create grazing surfaces and hiding places, while avoiding sharp décor. A mature aquarium with gentle circulation, an established biofilm and a secure lid is ideal, and open areas should remain available for movement.

Up to approximately 12 cm (4.7 inches) in total length, depending on the Tylomelania species. Females are often larger and more heavily built than males.

Rabbit Snails graze on algae, biofilm and decomposing plant matter, but an aquarium should also provide regular supplementary food. Offer algae wafers, sinking invertebrate pellets and vegetables such as blanched courgette, spinach, kale or green beans. Their diet should include a dependable source of calcium, such as mineral-rich foods or a suitable calcium supplement, to support shell growth. Remove uneaten vegetables before they decay and avoid relying on algae alone, especially in a clean or newly established aquarium.

Rabbit Snails are peaceful and can be kept with other calm, warm-water community fish such as small rasboras, peaceful tetras, honey gouramis, smaller rainbowfish and non-aggressive dwarf cichlids. They also coexist well with other peaceful snails and most ornamental shrimp, provided the shrimp are not kept with predatory fish. Avoid loaches, pufferfish, large cichlids, crab species and any fish known to attack or eat snails. Copper-based medications and copper-contaminated treatments are dangerous to them.

Rabbit Snails are livebearers and have separate sexes, so breeding requires at least one male and one female. A female produces a single, relatively large young enclosed in a white egg capsule, which hatches soon after being laid. The young snail is fully formed and begins grazing immediately. Stable, mature aquarium conditions and plentiful calcium-rich food support successful reproduction, although these snails usually breed slowly rather than producing large numbers of offspring.

Females are commonly larger and broader-bodied than males, although the difference is not always obvious. External sexing can be difficult, and reliable identification is usually easiest when observing breeding or examining the reproductive anatomy.
