Nerite Snails Facts Overview


Nerite snails are commonly regarded as the best snail in the aquarium hobby for obliterating algae from glass, rocks, live plants, driftwood, and other ornaments. Nerite Snails are absolutely peaceful, making them suitable for keeping with fish, shrimp, live plants, and other snails.

These snails belong to the Neritidae family, which includes more than 200 different species. The majority of these species may be found in brackish coastal waters, however a few can also be found in rivers and streams. As a result, some can be used in freshwater tanks while others can be used in saltwater aquariums.

They came from brackish waters in Eastern Africa, thus they would generally live in a mix of salty seawater and fresh river water in freshwater tanks. The majority of saltwater species come from the Pacific or Caribbean coasts.

Snails that have evolved to living in freshwater are excellent tankmates for your freshwater aquarium; they can survive for 1-2 years and grow up to an inch in length.

People keep these snails in their tanks mostly because they are one of the best algae eaters available. As long as the tanks aren't overstocked, this helps to maintain them clean. Snails aren't particularly active, but they're friendly creatures who shouldn't bother your other fish.


The anatomy of a snail consists of a hard, coiled shell on top of a muscular "foot" that moves side to side to propel the snail along. They have four sensitive tentacles as well.

If kept healthy, nerite snails can reach a length of 1 inch. Colors and markings vary by species, but they always have the same basic shape and size.

Habitat and Tank Conditions

They're mainly found in coastal areas like mangroves and estuaries, where there are plenty of rocks and other surfaces for algae to grow on; if you can duplicate this in your tank, they'll flourish.

Live rock can be used to create hiding spots in saltwater settings. Your snails can benefit from the algae that grows on the surfaces of live rocks.
