Product Overview

Trapdoor Pond Snails (Viviparus malleatus)

Trapdoor Snails are the preferred snail species for pond owners. Trapdoor Snails will survive in northern climates, will not eat live healthy plant tissue, and will not climb out of the water. Pond snails are helpful in keeping algae under control in your pond as they groom your plant containers, rocks, liner sides and plants. Trapdoor snails will consume excess fish food, fish waste and decaying leaves from the bottom of the pond, and therefore help to detoxify waste products. Trapdoor Snails are live-bearing (viviparous) -- they don't have as many offspring as most snails, and do not bear young as often, so are unlikely to overpopulate the pond, as is common with egg-laying snails. To have a positive effect on algae growth, a minimum of 10 snails per 50 square feet of pond surface is necessary. Large natural ponds would require at least 200 snails per acre to be effective. It also is important to have pond plants filter the pond and providing some shade, and to not overfeed fish, as the pond's ecosystem needs to be fairly balanced for the snails to make a significant difference.

    Fast service with shipping! Everyone arrived safe and ALIVE! I was very impressed with the packaging process of my items. I even referred you to my local pond Retailer. Thanks so much, these little things were exactly what I needed, and they’ve been cleaning the bottom of my pond wonderfully. Will definitely be coming back for more items!!

    We have an outdoor pond and got the snails to help with keeping it clean in a nature friendly way. They arrived safe and are all doing great. So cute to see them moving along stones and leaving a clean trail behind !
