Keeping Giant kokopu in an aquarium requires the right conditions.

Aquarium Information

  • Care level: expert
  • Temperament: peaceful
  • Diet: carnivore
  • Minimum tank size: 200 gallons (750 liters) for adults
  • Compatibility: Best kept in a species-specific tank or with other large, peaceful native New Zealand fish that tolerate similar cool, flowing water conditions. Avoid small fish as they may be prey.
  • Special requirements: Requires a well-oxygenated tank with strong filtration and good water flow. Abundant hiding places (rocks, logs, dense vegetation) are crucial. A substrate of gravel and sand is suitable. Mimicking a natural stream environment with cool, clean water is essential for their long-term health. They are sensitive to poor water quality and elevated temperatures.
