The Naso Tang, also known as the Orange-spine Unicornfish, darkens with maturity. Naso Tangs from Hawaii are often more brightly colored than those found in other areas. As a juvenile, the Naso Tang from Hawaii is dark gray with a blue stripe following the dorsal fin and an orange stripe in the anal fin. When matured, the body takes on a reddish-brown tone and the juvenile striping is supplemented with additional color. The tail takes on a lyre shape with a yellow vertical bar towards the back. Two orange patches appear at the peduncle spines near the tail. The face undergoes the largest change. A thin, black mask forms between the eyes and mouth. The mask is outlined with bright yellow and the lips develop a reddish-orange color.

A 135 gallon or larger aquarium is necessary to provide plenty of swimming room, places to hide, and a tight-fitting lid to prevent jumping to escape. It is aggressive towards other tangs, but peaceful with other fish in the tank.

The diet of the Naso Tang should consist of marine algae and vegetarian items such as spirulina, meaty planktivore preparations, and dried seaweed (brown is best).
