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.

Received living well. Put them in a large bowl with some plants with algae. Add my pond water to adjust them to my pond water. After 1 day they had babies!! After 2 days I added them to my pond. Spring the next year in the middle of Indiana after my pond froze over all winter they are still living. Love these big guys

Received in a very timely manner. ALL healthy, and moving about within hours. Pretty much had the bulk of my Algae cleaned up in a couple of days. Size was actually bigger than I expected. All around very happy that I purchased my JTS from Lilyblooms.

3 Three snails arrived dead. When I put them in the pond it became apparent that three more were dead. These were the smallest of the snails which arrived. The rest seem to be okay

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
