Product Description

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.

    Posted by on Oct 2nd 2017

    I hope all the snails are thriving, i can't see them in our indoor pond that is used in a grow dome. 2 didn't have snails in them but I got a couple extra in my order.

  2. Great Service! 5 Star Review

    Posted by on Sep 5th 2017

    I ordered snails for my small backyard pond and they were much bigger than I expected. They were packaged very well to make sure they survived shipping. They were all alive upon arrival. They arrived promptly and met all my expectations.

  3. Have ordered these twice 5 Star Review

    Posted by on Aug 24th 2017

    The first order I received healthy snails that were all moving around in a hour to a day. The second batch I ordered didn't fair as well but Lilyblooms has great customer service and stands behind the items they sell. They will happily ship replacement snails if there is any problems with the order received. I will order from them time and time again because of their customer service and products they offer.

    Posted by on Jul 19th 2017

    I was completely amazed that my snails came in as good a shape as they did. My package was sent to the PO arrived there Saturday afternoon I did not receive a slip in my box till Monday evening so it was Tuesday morning before I could go to town and pick them up five of them did not make it the other 10 look like they are in really good shape. The box had been damaged on the end and their bag had very little oxygen on it I was totally impressed with the aquatic plants that I bought. Wish I had purchased all of them from you. Nice size excellent quality I will definitely be ordering more

  8. Big healthy snails! 5 Star Review

    Posted by on Jun 11th 2017

    Full size adult snails. I was paying 3 times the price at a local nursery for the same thing. Very glad I ordered from LilyBlooms! Received the snails quickly, set them in my pond and they started to open within minutes. By the next morning they were all over the pond munching on algae.
