Nerite Snail
Neritina natalensis
Family: Neritidae
📍 Tropical regions worldwide
Nerite snails are among the best algae-eating invertebrates available, consuming green spot algae, diatoms, and film algae from glass, rocks, and plant leaves. They cannot reproduce in freshwater, so populations remain controlled. They may attempt to escape, so a tight-fitting lid is advisable.
