Yellow Poso Rabbit Snail (Tylomelania sp. )

Yellow Poso Rabbit Snail (Tylomelania sp.) — The Golden Giant of the Planted Aquarium

The Yellow Poso Rabbit Snail (Tylomelania sp.) is one of the most striking and characterful freshwater snails in the hobby. Endemic to the ancient Lake Poso in Sulawesi, Indonesia, this large, slow-moving snail is instantly recognisable by its elongated, turreted dark shell and vivid yellow-gold body — a bold, warm colouration that glows beautifully against dark substrate and lush green planting. With its distinctive rabbit-like face and deliberate, unhurried movement, the Yellow Poso Rabbit Snail is as endearing in personality as it is striking in appearance.

A Gentle Giant with Character

Rabbit Snails are among the most personable snails in the freshwater hobby. Their elongated bodies, expressive faces, and slow, methodical movement give them a charm that is entirely their own. The Yellow Poso variety’s vivid golden body creates a stunning contrast against its dark shell and the aquarium substrate, making it a natural focal point wherever it roams. Unlike many snails, Rabbit Snails are livebearers that reproduce slowly — producing only one or two offspring at a time — making population control effortless.

• Origin: Lake Poso, Sulawesi, Indonesia — ancient, mineral-rich freshwater lake
• Size: Up to 8–10 cm

• Diet: Omnivore — grazes on algae, biofilm, soft plant matter, and organic detritus; supplement with blanched vegetables, algae wafers, and sinking pellets
• Water Temperature: 26–30°C (requires warmer water than most freshwater snails — a heater is essential)
• pH: 7.5–8.5 (prefers hard, alkaline water reflecting its Lake Poso origins)
• Tank Size: Suitable from 40L upward; benefits from open substrate for foraging
• Breeding: Livebearing; produces one offspring at a time — population growth is very slow and manageable
• Note: Requires warm, hard, alkaline water — not suitable for soft or acidic setups. Avoid housing with assassin snails or any species that may prey on them.

Aquascape Compatibility

The Yellow Poso Rabbit Snail is plant-safe and an excellent companion for peaceful fish and dwarf shrimp. It thrives in warm, well-filtered aquariums with open sandy or fine-gravel substrate for foraging, driftwood, and leaf litter. It pairs beautifully with other Sulawesi species — Cardinal Sulawesi shrimp and other Tylomelania varieties — in a dedicated Sulawesi biotope setup.

Golden, gentle, and endlessly charming — the Yellow Poso Rabbit Snail is the living jewel that brings warmth, character, and colour to your planted aquarium.
