Keeping African Brown Knifefish in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: semi-aggressive
  • Diet: carnivore
  • Minimum tank size: 50 gallons
  • Compatibility: Best kept with similarly sized, peaceful to semi-aggressive fish that are not fin-nippers. Avoid very small fish as they may be seen as prey. Can be kept singly or in a group in a sufficiently large tank with ample hiding spots.
  • Special requirements: Requires a well-filtered tank with subdued lighting and plenty of hiding places such as caves, driftwood, and dense vegetation. A soft substrate is preferred. They are sensitive to poor water quality, so regular water changes are essential. They are nocturnal and will be most active after lights out. Provide a varied diet of live or frozen foods.
