Aquarium Information

  • Care level: expert
  • Temperament: semi-aggressive
  • Diet: carnivore
  • Minimum tank size: 75 gallons
  • Compatibility: Not recommended for typical home aquariums due to its invasive potential and specific care requirements. If kept, only with similarly sized, robust, and non-aggressive coldwater fish. Avoid keeping with smaller fish or invertebrates.
  • Special requirements: Requires excellent filtration and highly oxygenated water. A substrate of sand or fine gravel with some hiding spots (rocks, driftwood) is beneficial. Due to its invasive status, strict precautions must be taken to prevent its escape into natural waterways. In many regions, possession is illegal without specific permits.
