• Temperament: semi-aggressive
• Diet: carnivore
• Minimum tank size: 200 gallons
• Compatibility: Best kept in a species-specific tank or with other large, robust, and non-aggressive cold-water marine fish. Avoid small fish or invertebrates as they will be prey.

Live or frozen meaty foods are required. Not suitable for typical home aquariums due to size and temperature requirements.
