Japanese Trapdoor Pond Snails

Black Japanese Trapdoor Pond Snails - Algae Eaters

Japanese Trapdoor Snails (Viviparis malleatus) are the preferred species of snail for recreational and professional pond and water gardeners worldwide. Algae Eating Japanese Trapdoor Snails are one of the few snail varieties that can over-winter well and survive in harsher northern climates.

Algae Eating Japanese Trapdoor Pond Snails are a great asset in helping keep algae under control in your pond and water garden as they groom your plants, planting pots, and water garden rocks and walls.

Algae Eating Japanese Trapdoor Snails will tend to the bottom of the pond, consuming any decaying matter such as leaves, excess fish food, and even fish waste. Trapdoor Snails are live-bearing; they only breed a couple of times a year and will not take over your pond like other nuisance egg-bearing snails.

In order for your Trapdoor Snails to have a positive effect on algae growth, a minimum of 10 snails per 50 sq. feet will be needed, and farm ponds will need to have at least 200 Algae Eating Snails per acre to have any effect. Baby Japanese Trapdoor Snails are great forage for many mollusk-eating pan-fish and catfish species.
