Nerite Snail

(Neritina spp.)
Population Status in the Wild: Least Concern

Nerite Snails are a popular species of freshwater and brackish water snails belonging to the family Neritidae. They are native to tropical and subtropical regions of the world, including the coasts of Africa, Southeast Asia, and Central America. Known for their distinct, attractive shells, Nerite Snails come in a wide range of colors and patterns, including black, gold, green, and striped designs, making them highly sought after by aquarium enthusiasts. Their shells are typically smooth and hard, which serves as protection against predators.

Nerite Snails are primarily herbivores and are highly effective algae eaters, making them invaluable in aquariums for controlling algae growth on glass, rocks, and decorations. They have specialized radulas (tooth-like structures) that they use to scrape algae from surfaces. Their cleaning ability is one of the reasons why they are so highly prized in freshwater tanks. Despite their effectiveness in algae control, they do not typically eat live plants, making them safe for planted aquariums.

While Nerite Snails are well-known for their algae-eating skills, they also play a role in the ecosystem by contributing to the breakdown of organic matter. They are bottom-dwelling snails and prefer to stay close to the substrate, moving slowly over rocks and tank decorations. These snails are relatively small, typically growing to about 1 to 2 inches (2.5 to 5 cm) in size, and have a peaceful nature, making them suitable for most community tanks.

Nerite Snails are known for their remarkable ability to adapt to various water conditions. They can live in freshwater, brackish water, or even marine environments, depending on the species. However, they do best in tanks with stable water conditions, a temperature range of 72°F to 78°F (22°C to 25°C), and a pH level between 7.0 and 8.0. They do require a source of calcium in the water to maintain the strength of their shells, so adding calcium supplements or ensuring the water is hard enough is important for their health.

One unique feature of Nerite Snails is that they are known to occasionally leave the water to explore dry surfaces. This behavior is normal and doesn't harm the snails, but it can occasionally lead to escapes from aquariums if the water level is too low.

Fun Facts:
Nerite Snails are excellent algae eaters and can help keep aquariums clean by consuming algae from various surfaces.

They are safe for planted tanks, as they typically do not harm live plants.

Some species of Nerite Snails can adapt to brackish or even marine water environments, making them highly adaptable.
