Overview
The distinctive dorsal fins of the roosterfish normally remain retracted in a deep groove along the fish's back, but when the fish is excited the fins rise. There are two dark blue or black, curved bands on the flanks. One begins from the front and the other from the back of the first dorsal fin. Both run diagonally down the flanks towards the front of the anal fin then curve smoothly and run along the flanks to the tail base. The dorsal spines are banded with alternate dark and light stripes and the lower base of the pectoral fins is black.
