Hobbyists must also remember that all life forms tax their bioload capacity in a tank. Therefore we have to be careful with fish counts and overstocking.

A 10-gallon fish tank may be a great home for small fish, but larger species like the Bronze Cory Catfish and Sterbai Corydoras would require more space to thrive.

The tanks should be completely covered because Corys sometimes dart to the ground to eat or drink the air. Hobby users usually hear a snap or pop sound from their cats breaking the water surface and moving quickly to the bottom of the water reservoir.

Occasionally, substrate, plantings, or other decorative items may cover a tank’s floor. Therefore consider keeping the corydora catfish at least in 20-gallon tanks, as this size swimming space would be the minimum needed to survive and swim comfortably.

Ideal Tank Conditions for Cory Catfish

In nature, Cory catfish live in cold, slow-motion waters and soft sedimentary sediments. You will need a similar tank environment to keep coral catfish thriving. They are flexible and easily fit into most tanks, provided they are sufficiently big and kept well.

However, the ideal tanks should be covered as fish sometimes dart onto the top and grab a bite. They like hot water. Adjust the water temperature from 23° C to 26°C (71.6 to 78.8oF). Cory – catfish require softer substrates like sand or aquarium gravel on their bottom.
