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

    Have ordered these twice

    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.

    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

    The snails arrived with my plants and I couldn't be happier with them. They got to work right away and are doing great.

    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.

    MY Japanese Trapdoor snails arrived all alive. Two or Three took a couple days to start moving around but now doing good.

    Received my order promptly. A very nice batch of snails. After a few hours in the pond, they took off to do their job. Very pleased and will order more.

    ...a bit disappointed

    Posted by Unknown on May 23rd 2017

    The snails were not as large as I had hoped. I have ordered snails from other companies in the past and those were much larger. Also, I left the snails in a bucket of pond water so I could monitor their movement. After 2 full days, I could see only 2 or 3 actually moving around.
