Cory catfish are social fish that thrive in groups, so it is best to keep at least six individuals of the same species together to ensure they feel safe and exhibit natural behaviour.
While cory catfish primarily feed on bottom-dwelling insects, larvae, worms, and some plant matter, they will also consume flesh from dead fish if available in the tank.
Cory catfish are generally hardy and less prone to stress than some other small fish species, but they can be sensitive to sudden changes in water conditions, so maintaining stable water parameters is important for their health.
Cory catfish are excellent at helping keep the tank clean by scavenging leftover food particles and debris from the bottom, but they should not be relied on as a replacement for regular tank cleaning and maintenance.
