| Little pigmen.. Eyes unpigmented. Scattered melanophores occurred in the head region and in a line on the dorsal margin of the body. At 24h after hatching, a line of melanophores along the ventral surface of the body began to develop. At 24-36 h, the eyes became pigmented. At 42h, larvae seemed to be making feeding strikes, pigmentation on the ventral surface of the body increased. At 7-8 days, pigment cells were visible on the tip of the lower jaw and on the lower margin of the gill cover. | ||||

Gas bladder inflation also occurred at 10 days posthatch in 10-20% of larvae. By 13 d, the first traces of the juvenile color pattern began to appear, three pigmented lobes on the base of the anal fin developed. | ||||
