Aquarium Information

  • Care level: advanced
  • Temperament: semi-aggressive
  • Diet: carnivore
  • Minimum tank size: 500 gallons (for adult specimens)
  • Compatibility: Best kept in species-specific tanks or with other large, robust fish that cannot be swallowed. Avoid small or aggressive tank mates.
  • Special requirements: Requires a very large aquarium with ample swimming space. Excellent filtration is crucial due to their predatory diet. They are sensitive to poor water quality. A secure lid is essential as they are known jumpers. Live or frozen whole fish, shrimp, and other meaty foods are preferred. Due to their size and specialized needs, they are generally not recommended for typical home aquarists.
