Keeping Blue Tang in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: semi-aggressive
  • Diet: herbivore
  • Minimum tank size: 180 gallons
  • Compatibility: Generally compatible with other non-aggressive fish, but can be territorial towards other tangs or fish of similar shape/color. Best kept singly or in very large tanks with multiple tangs introduced simultaneously.
  • Special requirements: Requires a well-established tank with plenty of live rock for grazing and hiding. A strong protein skimmer and good filtration are essential due to their high waste production. Prone to marine ich (Cryptocaryon irritans) if stressed or in poor water quality. Requires a diet rich in marine algae and spirulina to maintain health and color.
