Spotted Unicorn Tang

Snapshot: This unicornfish rocks a sleek brown-to-grey body and flaunts dark vertical lines along its sides. Its white tail is clean and sharp, with a bold dark spot at the base. And that signature horn screams "royalty".
 
Other tidbits: Can grow up to a whopping 60cm or so! Distributed throughout the East Indian Ocean, West Indian Ocean, Australia, The Red Sea, Indonesia, New Zealand, Central/West Pacific.
 
Bare bones must know: Live-rock fish-only system, or reef aquarium with plenty of swimming room. Larger size aquarium needed. Well established and mature aquarium only.
