Keeping Unicorn Fish in an aquarium requires the right conditions.

Aquarium Information

  • Care level: advanced
  • Temperament: semi-aggressive
  • Diet: herbivore
  • Minimum tank size: 300 gallons
  • Compatibility: Can be kept with other large, robust fish. May be aggressive towards other tangs or similar-looking species, especially in smaller tanks. Best kept singly or in very large aquariums with multiple individuals introduced simultaneously.
