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 Trapdoor Snails

    All the snails arrived in excellent condition. They are happily eating away in my 40 inch bowl pond. I am having trouble with algae but after a few days I think they are making a difference. Would buy again. Thanks

    Snails arrived timely and apparently in good shape. I find it difficult to tell whether snails are alive or not on arrival. However I grouped them in several different places in my pond and they were all dispersed the next day so I assume they were alive. They were all mossy and covered with algae so are very hard to spot. Snails a got elsewhere last year came with clean shells and so are easier to spot. I actually haven't been able to find any of your snails in the pond since the first day. I can only hope they are down there somewhere doing their job.

    Smaller snails

    Posted by Pepper Morris on May 21st 2018

    I bought 10 they sent 11. I put 4 in my upper pond. They said it might take awhile for them to open up and start working. Those 4 were moving in 6 hours. Off to do their work in a 125 gallon upper pond. The 7 on the 1,000 pond were moving in 9 hours. I have seen 5 of them on the sides of the pond, assuming they are happy and eating and cleaning. I just have to bring them inside next fall. I have a 10 gal aquarium that they will rest in for the winter.

    I received my snails in really good condition. One of my snail was pregnant and Zi gad 6 babies the first day I received them. I received 11. I'm assuming since some were small. But overall very happy with them.

    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.

    Great Service!

    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.

    Have ordered these twice

    Posted by Diane Samples 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.

    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
