• Water Parameters: Cory fish thrive in stable water conditions, ideally with a pH range of 6.0 to 7.5 and a temperature between 72°F to 78°F. Regular testing of ammonia, nitrite, and nitrate levels is crucial, as high levels can be harmful to these sensitive fish.

• Tank Mates: Choosing compatible tank mates is important, as cory fish are peaceful and thrive in community tanks. They do well with other non-aggressive fish and should be kept in groups of at least six to ensure they feel secure and exhibit natural behaviors.
