Rabbit Snail
Tylomelania sp.
The Yellow-Faced Dinosaur (3-4.5 inches / 10-12 cm). The Rabbit Snail from the ancient Sulawesi lakes of Indonesia is undeniably one of the most bizarre, fascinating invertebrates in the hobby. It features a massive, long, heavy, cone-shaped shell. Its body is heavily wrinkled, often glowing a blinding bright yellow or orange, and features a long 'elephant trunk' snout with two drooping 'rabbit ears' (antennae). Instead of gliding smoothly, it clumsily 'drags' its heavy shell across the sand in jerking motions.

Care and observations
Water Chemistry and The Heat Mandate:
The Thermal Shock Error. Most beginners kill Rabbit Snails by freezing them. These snails come from volcanic tropical lakes where the water is permanently bathwater-warm (80°F - 84°F / 27°C - 29°C). If you keep them in unheated or cool tanks (below 75°F), they will become lethargic, lock themselves inside their shell, and slowly starve to death in forced hibernation. Furthermore, they STRICTLY require hard, alkaline liquid rock (pH 7.5 - 8.5). Acidic water will dissolve and horribly pit their majestic, long shells.
Substrate and Diet:
The Sand Requirement. Because they drag an incredibly heavy, long shell behind them, you MUST provide soft, fine-grained sand. Large, sharp gravel will trap the shell, exhausting and damaging the snail. They are phenomenal scavengers but terrible glass cleaners. They absolutely demand blanched vegetables (Zucchini, Carrots, Green Beans) and heavy calcium-fortified sinking wafers.
Reproduction (The Livebearer Snail):
The Single Baby Surprise. Unlike pest snails that lay hundreds of eggs, or Mystery Snails that lay massive pink clutches, the Rabbit Snail is a livebearer! Once every month or two, the female will drop a tiny, perfectly formed, fully shelled miniature 'baby' rabbit snail wrapped in a tiny white milky sac. It is the slowest, easiest breeding cycle to manage in the hobby.

- Calcium and minerals
- Estrema. L'acqua acida corrode immediatamente il lungo guscio ruvido.
- Molting
- Cresce strati sul guscio; la punta posteriore si erode naturalmente col tempo.
- Reproduction
- Non depone uova: è vivipara! Partorisce una sola, perfetta, singola lumachina minuscola alla volta.
- Compatibility
- Teme ferocemente i mangiatori di lumache (Botia, Pesci Palla) e necessita di fondo sabbioso (non ghiaia appuntita) per trascinarsi.
