Product Overview
Trapdoor Pond Snails (Viviparus malleatus)
Trapdoor Snails are the preferred snail species for pond owners. Trapdoor Snails will survive in northern climates, will not eat live healthy plant tissue, and will not climb out of the water. 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, and therefore help to detoxify waste products. Trapdoor Snails are live-bearing (viviparous) -- they don't have as many offspring as most snails, and do not bear young as often, so are unlikely to overpopulate the pond, as is common with egg-laying snails. To have a positive effect on algae growth, a minimum of 10 snails per 50 square feet of pond surface is necessary. Large natural ponds would require at least 200 snails per acre to be effective. It also is important to have pond plants filter the pond and providing some shade, and to not overfeed fish, as the pond's ecosystem needs to be fairly balanced for the snails to make a significant difference.

5 Snails
Posted by Heather on Jun 8th 2020
I was extremely impressed. They were all healthy and loved the fact they had moss like on them. Wish I could submit a photo. I ordered 10 and recieved 11 as a precaution if one didn't make it. All sank to the bottom but 2 . Had no worries , the next day they all down and certainly was moving about the pond. I will be ordering more products from you. Thanks very much for great service. Oh and it was 4 days later from paid to delivery. Awesome!!!

5 Japanese Trapdoor Pond Snails
Posted by Don Connolly on May 25th 2020
The snails arrived earlier than expected and were the best shipment I have ever obtained from any supplier. They were packed very very well and the quality of the snails was outstanding. All of the snails were alive and obviously well tended as there was absolutely no smell in the shopping bag. I have never received healthier snails at any price.

I bought these to help control the algae in my pond. Here's hoping the do the trick! The snails took a couple of days to come out of hiding but they are making happy trails now.

5 Cool Snails
Posted by Jesse Smith on May 11th 2020
9 of 11 snails woke up within 24 hours. The other 2 took about 48 hours. They're all chilling in the pond with my Koi and Goldfish, sucking algae at this time. Will buy from Lilyblooms again!
