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.
