Japanese Trapdoor Snails, Large

Japanese Trapdoor Snails (Viviparus Malleatus) work around the clock, eating decaying organic matter and algae from your aquarium or pond, and looking great while they do it!

The snails, approximately the size of a US quarter coin and larger, will grow to 1-1/2 to 2 inches in diameter and unlike most freshwater snails, Japanese Trapdoor Snails will not lay thousands of eggs and overrun your habitat. Trapdoor snails do well with koi, goldfish, crayfish, and most non-aggressive ornamental fish.

As for care, if the tank or pond fish are happy the snails will be too, scarfing down uneaten food, decaying leaves and plant matter, plus other unwanted organics. Trapdoor snails do not typically eat live plants.

The snails are hardy creatures but it may take a day or two to see movement, but you'll be surprised how much they get around once established. In ponds, you may not see them unless they come up toward the surface but if you have enough you'll certainly see the results of their work. To impact water clarity plan on 10 snails for every 50 square feet of surface area.
