Nerite snails are extremely popular for their  unique patterns and colors, as well as their practical benefits. They work hard to clean algae off of glass, plants, and decorations, they eat hair algae, and they keep your substrate clean and the correct color. In fact, nerite snails are widely believed to be the single best snail in the aquarium hobby for obliterating algae off of glass, rocks, live plants, driftwood, and other types of decorations. Although they thrive in both freshwater and salt water, they require salt water to reproduce. Thus, they are quite incapable of overpopulating any freshwater aquarium. Nerite Snails are completely peaceful, and therefore safe to keep with any fish, shrimp, live plants, or other snails.
