種の概要

Neritina natalensis is a Neritidae freshwater snail, the Zebra Nerite — among the best algae cleaners in the hobby. In the aquarium it stays a tireless, peaceful grazer. Plan on a 2–2.5 cm shell at 22–26 °C in medium-hard alkaline water; it cannot reproduce in freshwater, so it never overruns the tank.
