Freckled Tang

Snapshot: This surgeonfish rocks a beige suit with yellow polka dots as a juvenile. It grows up into a smoky brown stunner with golden highlights. The real showstopper is its face that is sprinkled with bright, freckle-like spots that steal the spotlight.
 
Other tidbits: Can grow up to 40cm or so. Distributed throughout the East Indian Ocean, Australia, Indonesia, Central/West Pacific Ocean.
 
Bare bones must know: Live-rock fish-only system, or reef aquarium with plenty of swimming room.
