Overview

Rabbit Snails (Tylomelania species) are unique freshwater snails from the ancient lakes of Sulawesi, Indonesia. Named for their rabbit-like faces with long, droopy "antennae" and wrinkled skin, these large, elongated snails have become increasingly popular in the aquarium hobby.

Unlike most aquatic snails, Rabbit Snails are livebearers, giving birth to fully-formed miniature snails. They come in stunning color varieties including chocolate, orange, yellow, and gold, with various shell patterns. Their slow, deliberate movements and distinctive appearance make them fascinating aquarium inhabitants.

Rabbit snails are Tylomelania from the lakes of Sulawesi. The shell can reach 2 to 5 inches, which is a wide span because the genus includes several species sold under one common name. Lifespan is listed at 1 to 3 years, care is easy to moderate, and the minimum tank is 20 gallons. They are not a cold-water pond snail and they are not a nerite. The water they come from is warm and mineral-rich, and a soft acidic community tank is how the shell fails.

Temperature on the card is 78 to 84°F, warmer than a standard tropical average. pH is 7.5 to 8.5, general hardness 8 to 15 dGH, and carbonate hardness 4 to 10 dKH. Sulawesi snails need ammonia held at 0 ppm and nitrite held at 0 ppm. Nitrate should remain under 20 ppm. If the room runs cool and the tank sits at 74°F for the sake of another fish, this snail is outside its range even when everyone else looks fine. Match the heater to the snail or do not keep it there.

Natural Habitat

Rabbit Snails come from a very specific environment: Your aquatic veterinarian and experienced Rabbit Snail owners can offer perspective tailored to your situation.

• Origin: Endemic to ancient lakes of Sulawesi, Indonesia
• Environment: Lake shores with sandy/muddy substrates
• Water: Warm, alkaline, mineral-rich water
• Diet: Detritus, algae, decaying vegetation

Tank Requirements

Rabbit Snails need warm, alkaline conditions.

• Tank Size: 20+ gallons (they're large and have significant bioload)
• Substrate: Sand strongly preferred for burrowing and feeding
• Temperature: Warmer than most snails (76-86°F)
• Filtration: Good filtration with moderate flow
• Plants: May eat soft-leaved plants; Java fern and Anubias safer
• Decor: Rocks, driftwood, and hiding spots

Water Parameters

Rabbit Snails require specific conditions reflecting their Sulawesi origins: Your aquatic veterinarian and experienced Rabbit Snail owners can offer perspective tailored to your situation.

Diet & Feeding

Rabbit Snails are hearty eaters with big appetites.

• Algae Wafers: Staple food; they love them
• Sinking Pellets: Fish pellets and bottom-feeder foods
• Blanched Vegetables: Zucchini, spinach, cucumber, carrots
• Algae: Will graze but not efficient algae control
• Calcium: Essential - cuttlebone, calcium blocks, or supplements
• Protein: Occasional bloodworms or shrimp pellets

Note: Rabbit Snails may eat soft-leaved aquarium plants if hungry. Keep well-fed to protect plants.

Rabbit Snail consistent chemistry, controlled feeding, and deliberate quarantine sit at the centre of sustained aquatic welfare; these factors drive outcomes more than brand-name products.

Behavior & Temperament

Rabbit Snails display charming behaviors: Your aquatic veterinarian and experienced Rabbit Snail owners can offer perspective tailored to your situation.

• Peaceful: Cannot harm tankmates
• Slow Moving: Deliberate, unhurried movements
• Burrowing: Often partially burrow in sand substrate
• Active Feeders: Enthusiastically approach food
• Social: Can be kept in groups without aggression
• Diurnal: Active during day, unlike many snails

Breeding is slow. They are live bearers, and a female releases a single miniature snail rather than a clutch of eggs. You will not wake up to a hundred rabbits. You also cannot count on a replacement when an adult dies at the short end of that 1-to-3-year span. The baby needs the same hard, warm water as the adult, and it is easy to crush under a rock the parent can shrug off.

They burrow. A sand bed deep enough for the shell to plow is the right substrate. Gravel chips the aperture and keeps them from moving the way they do in Sulawesi sediment. Feed them. Biofilm alone is not a reliable diet for a 4-inch Tylomelania. Algae wafers, blanched vegetables, and the occasional protein pellet keep them from wasting. An underfed rabbit snail rests, stops extending the long eyestalks, and is often mistaken for a shy healthy animal until the foot looks thin.

They are peaceful toward fish and can be bullied by curious cichlids that nip the exposed foot. Stock them with calm fish in that 20-gallon minimum, preferably longer than tall, with a lid because a rabbit snail will climb. Calcium in the KH and GH ranges above is what keeps the shell smooth. A pitted shell in a 7.0 pH tank is a chemistry problem, not a mystery disease. Fix the minerals before you add another snail to replace the first.

Color Varieties

Rabbit Snails come in many beautiful colors.

• Chocolate: Dark brown body and shell
• Orange Poso: Bright orange body with brown shell
• Yellow: Golden-yellow body coloration
• Gold Spotted: Gold spots on brown body
• Black: Dark/black body coloration
• White Spotted: White dots on dark body

Compatibility

Rabbit Snails are peaceful but have specific needs.

Good Tankmates

• Peaceful tropical fish
• Shrimp (compatible with Sulawesi species)
• Other peaceful snails (Mystery, Nerite)
• Corydoras and peaceful catfish
• Small plecos

Avoid

• Loaches (snail predators)
• Puffers (eat snails)
• Crayfish (may attack)
• Assassin Snails (may target juveniles)
• Large, aggressive cichlids

Breeding

Rabbit Snails are unique livebearers: Your aquatic veterinarian and experienced Rabbit Snail owners can offer perspective tailored to your situation.

• Sexing: Separate sexes; males have slightly different shell shape
• Live Birth: Give birth to fully-formed baby snails
• Gestation: 4-6 weeks
• Offspring: Usually 1-3 babies at a time
• Baby Size: Born relatively large (pea-sized)
• Frequency: Every 4-6 weeks when conditions are good
• Population: Slow breeding prevents overpopulation

Health Issues

Common Rabbit Snail health concerns: Leaning into Rabbit Snail-specific detail, instead of one-size-fits-all advice, consistently yields better results.

• Shell Erosion: From soft/acidic water; maintain proper pH and calcium
• Temperature Stress: Lethargy in cool water
• Parasites: Can carry internal parasites
• Starvation: Large snails need regular feeding
• Mantle Collapse: Serious condition; often from stress or poor water

Signs of Health

• Active movement and exploration
• Strong appetite
• Smooth shell without erosion
• Extended antenna and mantle
• Regular breeding (indicates comfort)

Food selection and exercise planning both benefit from referencing the breed's origin story — the resulting calibration is more accurate than a generic plan.

Is This Species Right for You?

A short set of Rabbit Snail-specific deep-dives worth bookmarking before a problem brings you back to the vet.

Rabbit Snails Are Perfect For:

• Those wanting unique, large snails
• Aquarists who don't want breeding explosions
• Warm water tropical tanks
• Keepers who enjoy hand-feeding
• Sulawesi-themed biotopes

Rabbit Snails May Not Be Ideal For:

• Cool water setups
• Planted tanks with soft-leaved plants
• Tanks with snail-eating fish
• Small tanks (significant bioload)
• Those wanting efficient algae control

Aquarium keeping is a hobby of specifics, and Rabbit Snail is no exception.

If you can commit to the maintenance schedule and the initial investment in proper equipment, a Rabbit Snail is likely to reward you with an engaging, long-term addition to your aquarium.

Cost of Ownership

The day-to-day value of these specifics is that they replace generic defaults with breed-specific ones, which is where better outcomes originate.

Small adjustments based on what you observe often yield the biggest improvements.

Rabbit snails, Tylomelania, come from the ancient lakes of Sulawesi and need warmer water than a cold goldfish tank, often the upper 70s to low 80s Fahrenheit, with hard water and calcium for the long shell. They eat biofilm, vegetables, and a pellet. They give birth to one fully formed tiny snail at a time.
