Spotted Cory Tank Setup

Plan for at least 75 litres (20 US gallons) with soft sand or smooth, rounded gravel - sharp substrate wears down their delicate barbels. Keep the water at 72-81°F with a pH around 6-7.8. Always keep a group of at least 6 of their own kind - kept alone or in pairs they tend to turn shy, nippy, or wash out in colour.

What Do Spotted 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.

Spotted Cory Tank Mates

Keep in groups of 6+. Sensitive to poor water quality and salt. The Spotted Cory is peaceful, which is the first thing to weigh up when you choose tank mates. It's a shoaling fish, so settle a group of 6 or more of its own kind before adding anything else - a stressed, lonely fish is far more likely to nip or hide. 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 Spotted Corydoras Good for Beginners?

Often recommended to beginners, but only after the tank is cycled and you can keep a proper school - not three fish in a new setup.

Spotted Cory - frequently asked questions

What size tank do Spotted Corydoras need?

Spotted Corydoras need a tank of at least 75 litres (20 US gallons). A bigger tank is always easier to keep stable, and gives them more room to settle in and behave naturally.

How many Spotted Corydoras should I keep together?

Keep a group of at least 6. Spotted Corydoras are a shoaling species and become stressed, lose their colour, or hide when kept singly or in pairs.

What water parameters do Spotted Corydoras need?

Keep them at 72-81°F with a pH of 6-7.8, steady rather than chased to an exact figure. In a cycled tank, ammonia and nitrite should both read 0 ppm, with nitrate kept low through regular water changes.

What do Spotted Corydoras eat?

Spotted Corydoras are bottom feeders. Give them sinking wafers, tablets, and frozen foods that settle on the substrate, ideally after the lights go off. Feed small amounts once or twice a day, and remove anything they don't eat.

Are Spotted Corydoras good for beginners?

Yes - Spotted Corydoras are a good beginner choice once the tank is fully cycled and you can keep a proper group. They are hardy but still need stable water and a school to feel secure.

Common mistakes with Spotted Corydoras

  • Buying fewer than 6 - Spotted Corys need a proper school to feel secure; isolated individuals hide, fail to colour up, or become stressed.
