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.

    Japanese trap door snails

    Posted by Gary D on May 19th 2022

    Received by USPS next day. These were Shipped the week before, but FED X printed out the wrong shipping label, so I did not receive them at my address. I contacted Lily Blooms, they were very nice about it and reshipped my order the next week by USPS. Lily Blooms has excellent customer service and I would recommend them. The snails arrived Alive and in good condition. They ship extras just in case one does not make it.

    Happy Snails

    Posted by Melissa Selleck on Apr 18th 2022

    All snails arrived alive and happy. Popped them into a container of pond water and two of them were opening up within less than 5 minutes. Added them to my pond and am hoping for the best. I highly recommend these snails for the pond.

    Snails were received in good condition (I think) and have been put into our fish pond. I hope they can survive colder water as the pond iced out only a few weeks ago.
