Nerite Snail ~ Neritina sp.

Nerite Snails are popular, hardy freshwater snails known for their efficient algae-eating abilities and uniquely patterned shells, which range in color and design from stripes to polka dots. Native to the coastal areas and freshwater rivers of Africa, Asia, and the Americas, they are highly valued for their peaceful nature and ease of care in aquariums, making them an ideal choice for both beginner and experienced aquarists.

- Size: 0.5-1 inch  
- Lifespan: 1-2 years  
- Temperament: Peaceful, non-aggressive  
- Group/Solitary: Can be kept singly or in groups  
- Food: Herbivorous, algae, algae wafers, fresh vegetables (zucchini, spinach)  
- Water Requirements: 72-78°F, pH 7.5-8.5, moderately hard to hard water

Nerite Snails are highly effective algae cleaners and can thrive in freshwater or brackish setups. They are non-invasive and don’t breed in freshwater, which prevents overpopulation in tanks. Nerites are compatible with most peaceful tankmates, but avoid placing them with fish that may nip at their soft parts. In addition to naturally occurring algae, they should be fed algae wafers and fresh vegetables like zucchini to ensure they have enough to eat, especially in clean tanks. These snails require hard, slightly alkaline water to support shell health, as soft water can lead to shell erosion and poor health.

In the wild, Nerite Snails are found in intertidal zones, estuaries, and freshwater rivers, where they graze on algae and biofilm along rocks and plants. Their strong attachment to surfaces helps them resist currents and predation, a behavior also seen in aquariums where they are often spotted on glass or decor.

Fun Fact: Nerite Snails cannot reproduce in freshwater; they need brackish or saltwater for their eggs to hatch. This unique trait makes them one of the few snails that won’t overpopulate a freshwater aquarium, making them a low-maintenance option for algae control.
