Olive Nerite Snail Tank Setup
Keep them in at least 40 litres (11 US gallons) with steady water at 72-82°F and a pH around 7-8.5. Healthy shells depend on enough calcium and clean, stable water.
What Do Olive Nerite Snails Eat?
They're grazers, so base their diet on algae, blanched vegetables, and spirulina-based foods rather than high-protein flake. A spotless tank with nothing to graze on leaves them thin and underfed.
Olive Nerite Snail Tank Mates
Excellent algae grazer. Does not breed in freshwater. Safe with most fish. The Olive Nerite Snail is peaceful, which is the first thing to weigh up when you choose tank mates. Good matches come down to the whole stocking list working together - temperature, tank size, and temperament - not any single label. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Olive Nerite Snails Good for Beginners?
Reasonable early choice after cycling. Buy after the tank has stable ammonia and nitrite readings, not the same weekend you fill it.
