The Blue Unicorn Tang (Naso brevirostris), also known as the Spotted Unicornfish, is a large, majestic Tang found among the Indo-Pacific Ocean. Their bodies range in color from grey to brown; some having striped or spotted designs. Most notable though is the elongated horn located inline with their eyes for which they are named. Reaching sizes of 24 inches, they should be housed in very large aquariums with plenty of room to swim. Their diet should consist of seaweed preparations or macro algae. They are best if not kept with other unicorn tangs, as they can be aggressive towards their own kind, but are peaceful towards other species.
