O-Ring Nerite Snail (Neritodryas javanica)
A rare patterned Nerite snail for planted tanks, glass algae, hardscape cleaning, and peaceful freshwater cleanup crews.
O-Ring Nerite Snails are beautiful algae-eating freshwater snails known for their distinctive ring-like shell pattern, active grazing behavior, and excellent planted tank utility. They are a great choice for aquariums that need help with glass, rock, driftwood, and hardscape cleanup while adding a more decorative snail variety.
Compared with common aquarium snails, O-Ring Nerite Snails offer a cleaner and more premium appearance. Their patterned shells make them visually interesting, while their constant grazing helps reduce soft algae, biofilm, diatoms, and film.

I added two O-Ring Nerite Snails to my planted tank and noticed a significant reduction in algae on the glass and driftwood within a week. Their shell patterns are striking and they don’t seem to harm the plants. A great addition for any freshwater aquarium.

The snails are active and clean regularly. I didn’t expect such a noticeable difference in biofilm after just a few days. They look beautiful and fit well with the tank’s decor.

Perfect for a planted tank. They don’t eat plants and keep the hardscape clean. The ring pattern on their shells is unique and adds visual interest.
