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

    Even though FedEx delayed delivery by 24 hours, the snails arrived healthy and happy. Within two hours of sitting in a tub of pond water, they were all running around. A real bonus was all the tiny baby snails we discovered in the tub with the mature snails. After just a week, the pone is already looking better. Thanks!!

    They were so big and healthy. I love Lillyblooms. I have never been dissatisfied with any of my orders. I live in a small town with no access to a good pond supplier. I recommend!

    I am so pleased with these snails! The shipping was very quick and we received 4 extra snails in our order of 40. We have been struggling with our pond water clarity for quite a while now and now it's amazingly clear! We put the snails in and within 10 days the water is wonderfully clear! We can't see the little guys working in there but they are certainly doing their job. We like to use natural methods as much as possible for the pond and this is great. I highly recommend LilyBlooms and these snails! Thank you so much!
