Acanthurus olivaceus
Water parameters are being added.
The Orangeshoulder Tang as a juvenile, it is solid yellow, with just the slightest hint of blue fringing on the anal and dorsal fins. As an adult, the front half of the body turns light gray and the back half takes on a dark gray-blue color. Above the pectoral fins is an eye-catching orange stripe that is outlined by the dark gray color. The tail takes on a lyre shape. A large aquarium is necessary to provide plenty of swimming room. It is not aggressive towards other Tangs. If housing more than one, it is best to add a juvenile to the aquarium that contains an adult.
