The Japanese Trapdoor Snail is a large, live-bearing freshwater snail prized for its excellent algae-eating abilities and peaceful nature. Unlike many aquarium snails, Trapdoor Snails reproduce slowly by giving birth to live young rather than laying eggs. Their beautiful olive, brown, or dark green shells make them a natural addition to aquariums and outdoor ponds.

Japanese Trapdoor Snails are livebearers. Instead of laying eggs, females give birth to fully developed baby snails. Reproduction is slow, making them unlikely to overpopulate an aquarium under normal conditions.
Japanese Trapdoor Snails are securely packaged with breathable materials and insulation when needed. Each snail is inspected before shipment to ensure it is healthy and active. Slow acclimation is recommended before introducing them into your aquarium or pond.
