The O Ring Nerite Snail is an eye-catching freshwater snail, loved for the circular, ring-like markings across its glossy shell. The pattern varies from one snail to the next, so every shell is a little bit unique. It is also one of the most useful clean-up crew members you can add to a tank.

O Ring Nerites are tireless algae grazers. They work steadily over glass, rocks, driftwood and hardscape, and they eat green spot algae, diatoms and biofilm that many other snails ignore. They are peaceful, safe for plants, and do not bother fish or shrimp, which makes them a good fit for community tanks, shrimp tanks and planted aquariums.

A well-known bonus is that freshwater nerites will not breed in aquariums, since their young need brackish water to develop. You may see small white egg specks on decor or glass, but they will not hatch in freshwater, so your tank will not be overrun with snails.

Keep the tank tightly covered, as nerites are known to climb out. Stable, mature water with some natural algae and a calcium source will keep the shell smooth and healthy.
