Aquatic Arts 1 Zebra Nerite Snail (Neritina natalensis - 1/2 to 1 inch in diameter) - Live Snail This snail's shell has a truly striking and beautiful pattern - it features gold and black zebra-like stripes running all the way down. (Due to shell pattern variations, your snails may not look identical to the image provided.) This is a Nerite Snail, so it absolutely never reproduces in freshwater - great for aquarium hobbyists who don't want snails reproducing in their tanks! Totally peaceful and safe for live plants, live shrimp, and live fish. Nerite Snails are widely known as one of, if not the most, voracious algae-eaters out of any snail. All Aquatic ArtsTM (formerly InvertObsessionTM) brand plants and animals come with a 100% live arrival guarantee, plus free email support directly from the owners!
