Keeping Spiny Eel in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: peaceful
  • Diet: carnivore
  • Minimum tank size: 30 gallons
  • Compatibility: Generally compatible with other peaceful, similarly sized or larger fish that will not be seen as food. Avoid very small fish or aggressive tank mates. Best kept with other bottom dwellers that are not overly competitive for food.
  • Special requirements: Requires a soft substrate (sand or fine gravel) for burrowing, as they spend a significant amount of time buried. Provide plenty of hiding places such as caves, PVC pipes, and dense vegetation. A secure lid is essential as they are known to be escape artists. They are nocturnal and most active during the night.
