Keeping Walking Catfish in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: aggressive
  • Diet: carnivore
  • Minimum tank size: 150 gallons (570 liters) for a single adult
  • Compatibility: Generally not compatible with other fish due to its predatory nature and potential for significant growth. Can be kept alone or with very large, robust, and equally aggressive species in extremely large aquariums, but this is not recommended for most aquarists.
  • Special requirements: Requires a tightly secured lid as they are notorious escape artists. Needs ample hiding places (caves, PVC pipes) and a soft substrate to prevent injury to their barbels. Excellent filtration is crucial due to their messy eating habits and large bioload. They can tolerate low oxygen levels but thrive in well-oxygenated water. Provide access to the surface for air breathing.
