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 trap door snails
Posted by Unknown on Jul 20th 2016
My original order had some doa's probable due to the intense heat both here and in Arizona. I was more that a little surprised that Lilly Bloom sent me some replacement snails without my knowledge or request. They are obviously a company with very high standards and I am grateful I chose them for my snails. I am giving the new batch time to acclimate in a bucket of my pond water with a bubbler. I will then put them into my 4000 gal pond. They should love it. I admit I was very concerned about reorder, but they have erased my doubt completely. I will reorder more snails from you and once again my appreciation to your wonderful customer service. A real rare treat. Thanks, Bill

We ordered 10 snails for our outdoor pond. We received 12 snails, all alive, plus two of the cutest babies. We placed them in a bucket with water from the pond and within 12 hours all of the snails were out of their shells and on the move. Great addition to our pond.

5 Nice, large snails

The snails were larger than I expected and all of them were alive and in good shape when they arrived. It didn't take long for them to "come out of their shells" and acclimate to the small pond I set them in. The order arrived very quickly.
