Keeping Marbled swamp eel in an aquarium requires the right conditions.

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.
