Neritina natalensis — Malaysian snail

The Malaysian Snail (Neritina natalensis) is a small nerite with a smooth, rounded shell that comes in variable color patterns of black, red, and cream. It is an effective algae grazer, particularly adept at cleaning glass and rock surfaces without reproducing in freshwater. Found in brackish and freshwater coastal habitats in Africa and Asia, it is hardy and adaptable to a range of water conditions.
