Long Nosed Arched Cory Tank Setup
Plan for at least 115 litres (30 US gallons) with soft sand or smooth, rounded gravel - sharp substrate wears down their delicate barbels. Keep the water at 73-77°F with a pH around 6-7.8.
What Do Long Nosed Arched Corydoras 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.
Long Nosed Arched Cory Tank Mates
The Long Nosed Arched Cory 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 Long Nosed Arched Corydoras Good for Beginners?
