Orange Shoulder Tang

Name: Orange Shoulder Tang
Scientific Name: Acanthurus olivaceus
Maximum Length: About 8 inches
Favorite Things: Long open swim lanes, strong flow, and constant grazing on algae; supplement with nori/seaweed sheets and quality herbivore pellets. Juveniles are bright yellow; adults turn slate gray with a bold orange shoulder bar.
Best Buddies: Generally peaceful with robust reef fish (wrasses, clowns, rabbitfish). Avoid mixing with similarly shaped tangs in tighter systems; handle carefully—sharp caudal “scalpel.”
