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 surgeonfish, especially those of similar size or shape. Requires ample swimming space and rockwork for grazing and hiding.
  • Special requirements: Requires a very large aquarium with strong filtration and excellent water quality. A constant supply of marine algae (e.g., nori) is essential to prevent head and lateral line erosion (HLLE) and maintain health. Provide plenty of open swimming space and live rock for grazing.
