Nerite Snail (Neritina sp.) is a beginner-level freshwater invertebrate that needs at least 5 gallons and 72-78°F. A hard-working algae-eating snail that will not overrun a tank because its eggs rarely hatch in freshwater. Needs hard water with some calcium to keep its shell healthy, and a lid, because it climbs.

San Diego water
Naturally suited to San Diego's hard, alkaline tap water once it is dechlorinated (the city uses chloramine, so use a conditioner that handles it). Learn the numbers in our San Diego tap water guide.
Before you buy
