The Zebra Nerite Snail (Neritina natalensis) is one of the most popular freshwater algae-eating snails, easily recognized by its bold black and yellow striped shell. With its distinctive zebra-like markings, peaceful temperament, and excellent cleaning ability, it makes an attractive and useful addition to planted aquariums and community tanks.
Zebra Nerite Snails are highly effective grazers that continuously feed on algae, diatoms, and biofilm growing on aquarium glass, rocks, driftwood, and décor. They are especially valued because they do not reproduce successfully in freshwater, allowing aquarists to enjoy their algae-control benefits without the risk of a rapidly expanding snail population.

Zebra Nerite Snails do best in established aquariums with a steady supply of natural algae and biofilm. Adequate calcium and mineral content are important for maintaining strong, healthy shells. Very soft or acidic water should be avoided, as it can gradually cause shell erosion.
Important Note
Female Nerite Snails may occasionally deposit small white eggs on hard surfaces such as rocks, driftwood, or aquarium glass. These eggs are harmless and generally will not hatch in freshwater.
Colourful, hardworking, and easy to care for, the Zebra Nerite Snail is an excellent choice for aquarists looking to add both visual interest and dependable natural algae control to their aquarium.
