The body and fins are greenish, in the dorsal fin the membrane between the fin rays is orange. A blackish band can often be seen on the soft-radiated sections of the dorsal and anal fin. The caudal fin base is black. The preopercular is lightly serrated with 18 teeth, as are interoperculars and suboperculars at their junction. In addition, the gill cover has two equally long spines.
