Aquarium Information
- Care level: intermediate
- Temperament: aggressive
- Diet: carnivore
- Minimum tank size: 75 gallons
- Compatibility: Best kept alone or with very large, robust, and fast-moving fish that cannot be swallowed. Highly predatory towards smaller tank mates.
- Special requirements: Requires a thick substrate (at least 6-8 inches) for burrowing, tight-fitting lid as they are escape artists, and plenty of hiding places. Good filtration is essential, but strong currents should be avoided. Can tolerate low oxygen levels due to air-breathing capabilities, but good water quality is still important.
