The Orange shoulder Tang (Acanthurus olivaceous) is also known as the Orange-epaulette Surgeonfish, Orange spot Surgeonfish, Orange band Surgeonfish and Orange shoulder Surgeonfish. As a juvenile the Orange Shoulder Tang is a solid yellow color, with just a hint of blue coloration on the edges of the fins.
As they mature towards adult hood the tail takes on a lyre shape and the front half of their body turns light gray while the back half takes on a dark grayish-blue color. Above the front pectoral fins an eye catching bright orange stripe that is outlined by the dark gray colored ring forms.
The Orange Shoulder Tang as with all tangs can be quite beneficial in helping control hair algae, as they like to spend their days picking at rockwork and occasionally sand in search for hair algae & other organisms to eat.
