Neritina zebra
A tireless algae grazer with bold stripes that earns its keep in any freshwater tank.
About
The zebra nerite snail (Neritina zebra) is one of those rare aquarium residents that combines genuine good looks with a practical purpose. Its shell is patterned with distinctive dark and golden-yellow stripes that run along the whorls, giving it a look that stands out against both substrate and glass. These snails are native to brackish coastal waters and estuaries of the Caribbean and parts of Central America, where they graze constantly on algae-covered surfaces. In the aquarium, that same grazing behavior makes them genuinely valuable. They will methodically work across glass, rocks, driftwood, and broad-leafed plants, cleaning off green spot algae, brown diatoms, and biofilm that other algae eaters ignore or miss. One of their best qualities for planted tank keepers is that they leave healthy plant tissue alone, focusing entirely on the surface growth. They are peaceful, slow-moving, and pose no threat to fish or other invertebrates. A beginner-friendly choice, they are hardy and tolerant of a range of conditions, though they do appreciate some mineral content in the water for shell health. One thing worth knowing: they cannot reproduce in pure freshwater, so you will not end up overrun with offspring the way you might with some other snail species.
