Overview
The Tylomelania sp. "Yellow", commonly known in the hobby as the Yellow Rabbit Snail or "Gelbe Perlhuhnschnecke", is a highly sought-after freshwater snail. Known for its distinct, rabbit-like face and peaceful demeanor, it makes a fantastic centerpiece invertebrate for specialized warm-water aquariums.
Distribution and Habitat
These unique snails are endemic to the ancient, warm-water lakes of Sulawesi, Indonesia, particularly the Malili lake system and Lake Poso. They inhabit shallow, warm waters with soft, sandy or muddy substrates interspersed with hard rock and wood, where they spend their days foraging for decaying plant matter and microscopic biofilms.
Description of Tylomelania sp. "Yellow"
As their name suggests, these snails boast a vibrant, golden-yellow to pale orange body that is heavily wrinkled, resembling an elephant's trunk. They feature long, drooping tentacles that give them a rabbit-like appearance. Their shells are elongated, conical, and deeply grooved, typically dark brown to black. It is perfectly normal for the apex (tip) of the shell to be slightly eroded or white, a natural occurrence in their native habitats and older specimens.
Keeping and Caring for Tylomelania sp. "Yellow"
Rabbit Snails are relatively undemanding provided their specific water requirements are met. They are entirely peaceful and should not be kept with aggressive, snail-eating fish like loaches or pufferfish. Because they drag a long, heavy shell, a soft sandy substrate is highly recommended to prevent shell damage and allow for easy, natural movement.
Tank size:
A minimum of 15 to 20 gallons is recommended. These snails can grow quite large, reaching up to 3 to 4 inches (7-10 cm) in length, and need ample floor space to roam and forage.
Water Parameters:
Originating from the unique environment of Sulawesi, they require specific, warm, and alkaline conditions to thrive and maintain healthy shells over their lifespan.
Temperature
They require warm water between 26°C and 30°C (79°F - 86°F). They will become sluggish, inactive, and prone to illness in cooler temperatures.
pH
An alkaline pH of 7.5 to 8.5 is crucial to prevent the deterioration of their impressive shells.
Hardness
Moderate to hard water is necessary. Aim for a GH of 4-15 and a KH of 3-10 to provide the necessary calcium for shell maintenance and growth.
Ammonia, Nitrite, Nitrate
Ammonia and Nitrite must always be at 0 ppm. Nitrates should be kept as low as possible, ideally below 20 ppm, through regular water changes and good tank maintenance.
Feeding the Tylomelania sp. "Yellow"
Yellow Rabbit Snails are ravenous omnivores and detritivores. While they will scavenge for leftover fish food and decaying plant matter, their diet must be actively supplemented. They relish powdered spirulina, sinking algae wafers, bottom-feeder pellets, and blanched vegetables such as zucchini, spinach, and green beans. Indian almond leaves or other hardwood leaf litter also provide an excellent, continuous natural food source.
Breeding Tylomelania sp. "Yellow"
Unlike many nuisance snails, Rabbit Snails breed very slowly, making overpopulation extremely unlikely. They are dioecious, meaning there are distinct male and female individuals, though they cannot be told apart externally. Females are viviparous (live-bearing) and will release a single, fully-formed miniature snail enclosed in a milky-white nutritional sac every few weeks. The baby will quickly eat the sac and begin foraging independently alongside the adults.
Conclusion
The Tylomelania sp. "Yellow" is a gentle giant of the freshwater snail world. Their bright colors, fascinating faces, and slow reproduction rate make them a highly rewarding pet for aquarists willing to provide the warm, alkaline waters they need. They are sure to be a captivating conversation starter in any suitable community or biotope aquarium.
