The Horned Nerite snails are a bit smaller than the other varieties of Nerites. They will not crawl out of your tank. They have a big appetite for algae and will be found on glass and on rocks. There are a variety of color patterns, like most nerites, each color and pattern is unique to each snail. We have seen the typical black and gold stripe, olive color and even a spotted snail with horns. We are happy to offer them again!
