Plan your setupBehaviour
Petricola Catfish are generally peaceful and social fish that do well in groups. They are active scavengers that spend much of their time foraging for food in the substrate. These catfish are known to be shy and prefer hiding spots among rocks or driftwood, especially during the day. They are most active during the evening and night.
Tank planning
Maintaining good water quality is crucial for the health of Petricola Catfish. Provide plenty of hiding spots and caves in the aquarium to make them feel secure. Keep the tank well-aerated and maintain a stable water temperature. Regular water changes are essential to keep nitrate levels low.
