The species varies greatly in colour. Males are generally pale bluish-green, greenish-brown to yellowish (paler below), with narrow orange to reddish stripes along the scale rows, and a distinct midlateral stripe that may be blackish to yellowish anteriorly, becoming bluish-green or brownish-green on the tail base. A yellow or orange spot is usually present on the gill cover, and the dorsal, anal and caudal fins have bright reddish, yellowish and orange patterns.
Females and juveniles are silvery with translucent or faintly pigmented fins.
