Choosing the right Corydoras catfish for your tank
Corydoras are social and should be kept in groups of six or more of the same species. Most stay under 3 inches, so a 20 gallon tank is a comfortable home for a school, and dwarf species like pygmy corys can live in 10 gallons. Use fine sand or smooth gravel to protect their sensitive barbels. Most corys thrive at 72 to 78°F with a pH of 6.5 to 7.5; sterbai corys tolerate warmer water, while peppered corys prefer it cooler.
Corys are ideal community fish alongside tetras, rasboras, guppies, and bettas. They are foragers, not janitors, so feed sinking wafers, pellets, and frozen foods that reach the bottom. It is normal for corys to dart to the surface for a gulp of air.

Corydoras are bagged with oxygen, insulated, and shipped overnight within the USA. Every fish is covered by our live arrival guarantee: contact us within 2 hours of delivery about any DOA and we will issue store credit or send a replacement.
Frequently asked questions
How many Corydoras should I keep?
At least six of the same species. Larger groups are more confident, more active, and more fun to watch.
Do Corydoras need sand?
Sand or very smooth gravel is best. Sharp substrate wears down their barbels, which they need to find food.
Can Corydoras live with bettas?
Yes. Corys are peaceful bottom-dwellers that ignore bettas and make excellent tankmates in a 10 gallon or larger tank.
