Yolk-sac absorbed at about 2.2 mm. Pigmentation: a single melanophore on the nape, dorso-ventral pair midway back on body, and the dorsal surface of gut is pigmented. This pattern persists until about 6 mm, then pigment becomes scattered. Distal pigments present in pelvics. Sequence of fin development: pelvic (2.75 mm); second dorsal and anal (7 mm) |
