Also called the Pacific Blue Tang, Regal Tang, Hepatus Tang, Palette Tang, and the Hippo Tang. This fish is a royal blue, with a black marking on the body which resemble a painters palette. They have a yellow tail and yellow blotches on their pectoral fins. An active fish that requires plenty of swimming room. A tank of at least four feet in length is recommended. While they are very docile as juveniles and can be kept in groups, they may fight with other Blue Hippo Tangs when mature. Provide hiding places large enough to accommodate, as this fish can grow up to 12 inches. The Blue Hippo Tang will lay down on its side when it does not have a good hiding place available. They also display this behavior frequently as juveniles, when stressed, or transfered to new surroundings. As most tangs mainly feed on algae, this fish requires live rock for grazing.
