Keeping Blue Catfish in an aquarium requires the right conditions.

Aquarium Information

  • Temperament: semi-aggressive
  • Diet: carnivore
  • Minimum tank size: 500 gallons
  • Compatibility: Best kept in species-specific tanks or with other large, robust, semi-aggressive fish that can tolerate brackish conditions. Avoid small or timid tank mates.
  • Special requirements: Requires a very large aquarium with excellent filtration due to its size and waste production. Substrate should be soft sand to protect its barbels. Provide ample swimming space and some hiding spots with large rocks or driftwood. Can tolerate a range of salinities from freshwater to brackish, but stable conditions are preferred.
