Product Overview

Black Japanese Trapdoor Snails (Viviparis malleatus)

The Black Japanese Trapdoor Snails (Viviparis malleatus) are the preferred snail species for pond owners and water gardeners. Japanese Trapdoor Snails are one of the few varieties that will survive in northern climates. 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. Japanese Trapdoor Snails are live-bearing and only breed twice a year. They will not over reproduce and become a nuisance like egg laying snails. To have a positive effect on algae growth, a minimum of 10 snails per 50 square feet is necessary. Large natural ponds would require at least 200 snails per acre to be effective.

Minimum order of 10

    I love the trapdoor snails ! They do such a great job at cleaning our waterlily container and are super cute. Don't add harmful chemicals, but let nature clean !

    Pond Snails

    Posted by Kelly on Jun 26th 2021

    I purchased these in early spring in NY. I had my doubts as they were not "active" as I transitioned them to my pond, and then did not see them at all in the pond. However, my pond is much clearer and I have now not only seen live adult snails, but now have some babies.

    We’ve purchased Japanese trapdoor snails from Lilyblooms the past couple years. All snails survived shipping and they always throw in an extra couple!
