The name 'Naso Tang' simply describes its genus while its other common names, the Lipstick Tang or Orangespine Unicornfish, touch on its outstanding appearance. Orangish lips and a pair of spines surrounded by a bright orange area on either side of the caudal peduncle are some of the distinct features that make this fish stand out. Along with these add a strong yellow line running from the back of the mouth up to the eye and bold colored stripes on the top and sometimes bottom fin, and you have a true beauty. They grow to 17.7,” with males being larger and live up to 45 years! The Naso Tang is best left for intermediate aquarists.
