The Orange Shoulder Tang (Acanthurus Olivaceus) should be housed in a 180 Gallon or larger aquarium, which is necessary to provide a lot of swimming room.
The Orange Shoulder Tang has three phases of color changes. The first as a juvenile, they are a solid yellow and the slightest blue on the tips of their anal and dorsal fins. As they change and become an adult they have a half light grey and half dark blue/grey color body. Above the pectoral fin a bright orange stripe is outlined in dark grey. The tail also takes shape into a lyre tail. At full show size the Orange Shoulder Tang becomes a magnificent dark blue/grey and is strikingly beautiful with its orange stripe above its pectoral fin. These fish are not aggressive towards other tangs, but if housing more than one a juvenile should be added to the aquarium that contains an adult.
The Orange Shoulder Tang should be offered plenty of marine based seaweed and algae. This will strengthen their immune system, reduce aggression and improve their overall health. They may eat meaty foods along with the other fish in the aquarium, but it should be fed using a veggie clip that can hold seaweed 3 times a week.
