Trapdoor Pond Snails (Viviparis Malleatus)
Black Japanese Trapdoor Snails (Viviparis malleatus)
The Black Japanese Trapdoor Snails (Viviparis malleatus) are the preferred snail species for pond owners and water gardeners. Japanese Trapdoor Snails are live-bearing and they will not over reproduce and become a nuisance like egg laying snails. To have a positive effect on algae growth, a minimum of 10 snails per 50 square feet is necessary. Large natural ponds would require at least 200 snails per acre to be effective.
Trapdoor Snails are also fun to have in aquariums and without the worry of over population.
Minimum order of 10
