Green Urchin Nerite Snail (Neritina sp.)
The Green Urchin Nerite Snail (Neritina sp.) is one of the most unique freshwater algae-eating snails available. Known for its distinctive spiky shell texture and attractive green, olive, and dark patterned coloration, this unusual Nerite Snail adds both beauty and functionality to planted aquariums, shrimp tanks, and community fish setups.
Like other Nerite Snails, the Green Urchin Nerite is an exceptional algae grazer that helps keep aquarium glass, rocks, driftwood, and decorations clean without harming live plants. Because Nerite Snails cannot reproduce in freshwater aquariums, they provide natural algae control without creating unwanted snail populations.

Aquarium Setup
