Japanese Trapdoor Snails are named for their operculum, which is a tough plate that protects the snail by forming a seal at the edge of the snail's shell when its soft body is retracted inside. They are also known by the name Chinese Mystery Snails. They are large for freshwater snails, and are quite unusual-looking yet attractive. They vary in coloration and patterns, but usually have more natural-looking colors such as brown and green. They also serve some very useful purposes. They clean algae off of glass, plants, and decorations, and they keep your substrate clean and the correct color. They are totally safe with any fish, shrimp, or plants, and are completely peaceful. Trapdoor Snails are quite large as adults, growing up to 2" in size.

RECOMMENDED TANK PARAMETERS:
- PH level range: 6.5 to 8.0
- Temperature range: 68 to 85 degrees Fahrenheit
- Water type: Soft to medium hard
- Recommended Aquatic Arts tank mates: Other types of snails (Nerite snails, Mystery Snails, Sulawesi Snails, etc.), dwarf shrimp (such as Blue Velvet shrimp, Sakura Fire Red Cherry Shrimp, Bee Shrimp, etc.). They can also be kept with small to medium-sized, non-aggressive fish.
- Additional notes: With trapdoor snails, it's a good idea to make sure the water line in your aquarium isn't too high, as these snails tend to climb up to the water line to breathe air. Other than algae and biofilm, they also eat fish or invertebrate pellets and blanched vegetables such as zucchini, kale, spinach, or cucumber. Snails are very sensitive to copper, so watch out for copper if you use tap water in your tank.
