The Naso Blonde Tang, also known as the Orange-spine Unicornfish, darkens with maturity. As a juvenile, it is gray with a yellow stripe on both the dorsal and anal fin. When matured, the body takes on a darker bluish-gray tone and the juvenile striping is supplemented with additional color. The tail takes on a lyre shape and two yellow patches appear at the peduncle spines near the tail. A thin, black mask forms between the eyes and mouth, and the lips develop a yellow color. Naso Tangs from Hawaii are often more brightly colored than those found in other areas.
A 125 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.
Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae. This will strengthen their immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or use a veggie clip, and feed at least 3 times per week. Sea Veggies, Seaweed Salad and Ocean Nutrition are all ideal products and are very easy to use.
