Marbled Limpet Nerite Tank Setup
Keep them in at least 20 litres (5 US gallons) with steady water at 73-82°F and a pH around 7-8.5. Healthy shells depend on enough calcium and clean, stable water.
What Do Marbled Limpet Nerites Eat?
They're bottom feeders, so give them sinking wafers, tablets, or frozen treats like bloodworm once the lights go down. Flakes that never reach the bottom leave them hungry even when the tank looks well-fed.
Marbled Limpet Nerite Tank Mates
Sensitive to copper and some medications. The Marbled Limpet Nerite 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 Marbled Limpet Nerites 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.
