The Brown Sailfin Tang is yellow, dorsally, and brown, ventrally. These colours gradually get darker from front to back. The body is covered with fine, intricate, light blue markings. The tail is a solid brown colour. Juveniles are a little more attractive, with larger dorsal and anal fins and a slightly purplish body color.
A larger aquarium is necessary to provide plenty of swimming room. It is aggressive towards its own species or tangs in general, and best kept with only one per 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 foods. 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.
