The Goldtail Angel Fish has a body of mottled-brown with vertical white stripes. There are several bright sapphire-blue stripes on the head, and the tail is a dull yellow rimmed in the same sapphire-blue. As a juvenile, the tail is clear in coloration.
The Chrysurus Angelfish requires an aquarium with multiple hiding places and large amounts of live rock for grazing.
The Gold Tail Angel Fish may nip at stony and soft corals and clam mantles, but may be kept with small-polyped stony corals and somewhat noxious soft corals. When stressed, the Chrysurus Angelfish makes an unusual clicking sound.
As other angelfish, it is hermaphroditic, and there are no distinguishing characteristics to differentiate males and females.
The diet of the Gold Tail Angel Fish should include marine algae, mysis or frozen shrimp, and chopped meaty foods.
