The Japanese Trapdoor Snail is a great asset for controlling pond algae. It is one of the few varieties that can survive Northern winters. The Japanese Trapdoor Snail will keep your pond plants groomed with minimal damage to the plants. They also clean up the sides of ponds and water gardens, feeding on uneaten fish food and decaying debris on the pond floor. The Japanese Trapdoor Snail makes a great overall pond cleaner.
The Japanese Trapdoor Snail originates from ponds and slow-moving streams with some vegetation and a muddy substrate. It is also known as the Chinese Mystery Snail and is a live bearing species. The shells of Japanese Trapdoor Snails can vary significantly in color and pattern, but are usually brown/gray coloration.
Viviparus malleatus is an omnivore that will consume algae (managing it and providing crystal clear water and healthy fish), plant matter, vegetables, fish food, frozen foods, and live foods. The Japanese Trapdoor Snail is a very peaceful animal and should not be housed with any animals that would like to make a meal of them.
