Rabbit Snail Breeding Guide: Tylomelania Live Bearers

Rabbit snails are unlike any other freshwater snail in the hobby. These elegant Tylomelania species from the ancient lakes of Sulawesi give live birth to fully formed miniature snails, wrapped in a milky egg sac. If you are looking for a thorough rabbit snail breeding guide, Gensou Aquascaping at 5 Everton Park, Singapore has kept and bred multiple species over the years. Here is what works.

Species and Varieties

Tylomelania encompasses dozens of species, many still undescribed scientifically. The most commonly available in Singapore include the yellow rabbit snail (Tylomelania zemis), chocolate rabbit snail, orange poso and golden spotted varieties. They range from 5 to 12 cm in adult shell length depending on species. Their elongated, conical shells and rabbit-like faces with drooping oral tentacles give them an unmistakable charm.

Prices vary widely. Common yellow and chocolate varieties cost $5-$10 each, while rarer colour forms like orange poso can fetch $15-$25 on Carousell and specialist forums.

Ideal Water Parameters

Rabbit snails originate from Lake Poso and the Malili lake system in Sulawesi, where water is warm, moderately hard and slightly alkaline. Aim for pH 7.5-8.5, GH 6-12, KH 4-8 and temperature 26-30 degrees C. Singapore’s warm ambient temperature is perfect, eliminating the need for heaters in most setups.

PUB tap water is softer than ideal for rabbit snails. Supplement with crushed coral, aragonite or a GH/KH remineraliser to maintain shell health. Soft, acidic water erodes their shells over time, leading to pitting and thinning.

Tank Setup for Breeding

A 40-litre tank comfortably houses three to four adult rabbit snails. Use sand substrate, as these snails love to burrow with only their heads exposed. Fine pool filter sand or aquarium sand works well. Avoid sharp gravel that can damage their soft bodies. Include driftwood, smooth rocks and live plants like Anubias and java fern, which rabbit snails generally leave alone.

Ensure the tank has no gaps in the lid. Rabbit snails occasionally climb above the waterline and can fall outside the tank if openings exist.

How Rabbit Snails Reproduce

Unlike most aquatic snails, Tylomelania are not hermaphrodites. They have separate sexes, though distinguishing males from females externally is nearly impossible without examining the reproductive structures under the operculum. The simplest approach is to keep a group of four to six and let nature take its course.

Females produce one baby at a time, encased in a creamy white egg sac that she deposits on the substrate. The baby snail emerges within hours, already measuring 5-8 mm with a fully formed shell. Reproduction happens every four to six weeks per female under good conditions.

Feeding for Breeding Condition

Rabbit snails are omnivores with a preference for decaying plant matter and algae. Feed blanched spinach, zucchini, carrot slices, sinking algae wafers and calcium-rich foods like cuttlebone shavings. A varied diet with adequate calcium is essential for shell growth in both adults and babies. Without sufficient calcium, shells develop thin spots and become prone to cracking.

Remove uneaten vegetables after 12-24 hours. Rabbit snails are slow eaters compared to nerites or mystery snails, so do not panic if food sits untouched for several hours before they find it.

Raising Baby Rabbit Snails

Baby rabbit snails are independent from birth and require no special care beyond what the adults receive. They burrow into the sand immediately and begin grazing. Growth is slow; expect roughly 1 cm of shell growth every two to three months. It takes 12-18 months for most species to reach adult breeding size.

Predation is the main risk to babies. Loaches, puffers and large cichlids will eat baby rabbit snails. Keep them in a species-only or shrimp-and-snail community for the highest survival rates.

Common Issues

Shell erosion from soft water is the number one health problem. White, chalky patches on the shell tip indicate calcium deficiency or acidic conditions. Correct water hardness and add supplemental calcium to halt further damage. Existing erosion cannot be repaired, but new growth will be healthy.

Rabbit snails are also sensitive to copper-based medications. If you need to treat fish in a shared tank, move the snails to a separate container first. With patience and stable, mineral-rich water, breeding rabbit snails in Singapore is straightforward and deeply satisfying.
