Algae Eating Black Japanese Trapdoor Pond Snails are the preferred species of snail for recreational and professional pond and water gardeners world-wide. Japanese Trapdoor Snails are one of the few snail varieties that can over-winter well and survive in harsher northern climates. Japanese Trapdoor Snails are a great asset in helping keep algae under control in your pond and water garden as they groom plants, planting-pots and water garden rocks and walls. Japanese Trapdoor Snails will tend to the ponds bottom, consuming any decaying matter such as leaves, excess fish food, and even fish waste.
Black Japanese Trapdoor Pond Snails are live-bearing; they only breed a couple of times a year and will not take over your pond like other nuisance egg bearing snails can and will. In order for your Japanese Trapdoor Snails to have a positive effect on algae growth, a minimum of 10 snails per 50 sq feet will be needed, and farm ponds will need to have at least 200 snails to have any positive effect at all.
Please Note: There is a 5 snail minimum when ordering with other pond plants, and a 20 snail minimum without any plant order.
