Seashells from Black Racer Nerite Snails shine like ebony in your aquarium, adding a sophisticated aesthetic while also serving a practical purpose. They eat hair algae and keep your substrate clean and the correct color as do all Nerite snails. They clean glass, plants, and decorations.
The Nerite Snail is widely regarded as the best snail for eating algae in the aquarium hobby. All fish, shrimp, and plants are completely unaffected by them. Because they can only reproduce in saltwater, Nerite Snails will never overrun your aquarium (as some freshwater snails are known to do).
These Nerite Snails are our largest Nerite Snail, even beating out Tiger Nerites and Zebra Nerites in terms of size. The snails you receive will be between a half-inch and a full inch in diameter when you get them, but they can grow up to a full inch and a half in diameter. Additionally, they are the only Nerite Snails that are significantly faster and more active than any other type of Nerite Snail.
The water line in your aquarium should not be too high when keeping any Nerite Snails. These snails have a tendency to climb above the water line. Furthermore, Nerite Snails are unable to survive in water that contains excessive levels of nitrate. Copper is extremely toxic to freshwater snails, so avoid using tap water in your aquarium if you can help it.
