Orange Shoulder Tang
Acanthurus olivaceus


Origin: Indo-Pacific – Hawaii, Philippines, Indonesia, Great Barrier Reef
Size: Up to 35 cm


Reef Compatibility:


  • Small Fish Safe: ✅ Yes
  • Invert Safe: ✅ Yes
  • Coral Safe: ✅ Yes


Diet: Herbivore – primarily grazes on marine algae; supplement with nori, spirulina, and quality herbivore pellets. Will also accept mysis and brine shrimp.
Care Level: Moderate to Difficult – requires a large, stable aquarium (at least 500 L) with abundant swimming space and grazing opportunities.
Aggression: Semi-aggressive – generally peaceful but may be territorial with other tangs, especially of similar shape.
Captive-Bred Available: No


Notes:
Juveniles are yellow with faint markings, while adults develop the signature grey-blue body and bold orange shoulder patch. This species is active, fast-moving, and best suited for larger reef aquariums. Provide ample live rock for grazing and open water for swimming.


Why We Like It:
The Orange Shoulder Tang is both graceful and striking, with its dramatic colour change from juvenile to adult. A powerful swimmer and diligent grazer, it makes an impressive centrepiece for a large reef display.
