Care and Environment

Providing optimal care for the Bannertail corydoras involves replicating its natural habitat and meeting its specific needs.

What is the minimum tank size for a Bannertail corydoras?

A minimum tank size of 71 liters (approximately 19 gallons) is recommended to accommodate a small group of these social fish.

What are the ideal water parameters for Bannertail corydoras?

Maintain water temperatures between 21°C and 26°C (70°F to 79°F), with a pH range of 6.5 to 7.5, and water hardness between 5 to 12 dGH.
