The Blue (Hippo) Tang, also known as the Regal Tang, is one of the most recognizable and beloved reef fish in the aquarium hobby. With its vivid royal-blue body, bold black patterning, and bright yellow tail, this species brings instant color and movement to large reef aquariums.
Tank-raised specimens are well adapted to aquarium life, readily accept prepared foods, and generally acclimate more easily than wild-caught individuals. Active and intelligent, the Blue Tang is constantly on the move and thrives in spacious systems with strong water movement and excellent water quality.
While peaceful overall, this species requires ample swimming room and a consistent feeding schedule to maintain health and coloration. It is best suited for established reef aquariums with experienced aquarists prepared to meet its space and dietary needs.
