The Naso Tang, also known as the Lipstick Tang or Orangespine Unicornfish, is a species of tang native to the Indo-Pacific region. They have a distinctive elongated body shape and a small mouth with protruding lips. They are primarily dark blue with bright yellow highlights on its fins and tail. It also has a unique bright blue stripe along the edges of its dorsal and anal fins. Juvenile Naso Tangs have a more yellowish coloration and lack the blue stripe on their fins. In the wild, the Naso Tang feeds on a variety of algae and other plant material, but in captivity, they can be fed a diet of marine-based seaweed, vegetables, and high-quality commercial pellets or flakes.
