Under conditions of reflectied light, the fish sometimes displays a fine lateral band from the opeculum to the end of the caudal peduncle (Walker, 1971, p. 98) this being an olive-gold hue. The fins, with the exception of the dorsal fin, are hyaline, the relation of the pectoral and pelvic fins being typical of the ostariophysans (fishes possessing an auxiliary mechanism for detecting sound consisting of a set of internal bones called the Weberian Ossicles). In such fishes, the

There are three vertical black bars which contrast with the grey-brown ground colour of the body, there is one bar running down from each dorsal fin and the last bar is on the caudal peduncle. There is a characteristic black ‘eye-spot’ surrounded by a yellow ring within the first bar. The first dorsal fin has a dark leading edge while that of the pelvic fins is white.
