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.

We ordered the Japanese trapdoor snails to clean the algae in our pond and large outdoor aquarium. Within a few hours of placing them in the pond and aquarium, they went to work cleaning. A week later we can see a noticeable improvement.

Snails are large and were delivered within a few days. All arrived alive with exception of 4 floaters, that's the reason for 4 stars. Excellent service!!

The snails showed up on time, wrapped in wet newspaper. I followed the instructions to introduce then to my pond. Everyone of them survived are eating away. Thanks

5 excellent

excellent way to keep pond cleaned naturally. Recommend draining and cleaning pond though if it's very dirty. We had to do so after two weeks of no results; pond has been clear for nearly three weeks now in 90 plus weather and no filters on koi pond, just got water features and aerator.

3 Snails
Posted by Chloe Johnson on Jun 16th 2020
The size and amount of the snails were great, however the box was torn, smashed and had been tapped up. One side of the package of snails was smashed. (I think 3-4 snails) the rest were fine. I have not seen any evidence the them opening up yet as my pond has many hiding places.

1 Don’t buy!!

My pond was crystal clear until these were put in. They arrived late, took over a week to wake up, were covered in green and now my pond has not been clear since. Very disappointed I wasted my $. In fact I’ve fished out as many as I could find and tossed them in the ditch.

They arrived fast to Texas. I was nervous waiting on them to land safely. All look good and 2 are already crushing around
