Description

Jumbo - Black Japanese Trapdoor Snails (Viviparis malleatus)

Note: Our Jumbo snails are the same type as our regular size snails. They are simply larger more mature snails. See the picture for sizing.

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.

    I couldn't believe how fast the snails cleaned up my pond. I bought 10 and they sent me 11 just in case 1 didn't make it alive. My pond is 1500 gal. And only took them a couple of days to clean up all the algae. What a difference. Have had them a couple of weeks now and have a nice clean pond.

    Snails arrived in great shape. They started to move around the pond after a few hours once they got acclimated to my pond.
