Eyes unpigmented; mouth undeveloped; light pigment between eyes; narrow gap between yolk and anus; vent halfway between snout and tip of tail. Yolk-sac absorbed at about 2.8 to 3.0 mm. Pigmentation: melanophores confined to dorsal and dorso-lateral regions of body and extend to the tail. Pigment soon aggregates into three patches - one at vent, one midway between vent and tip of tail and one near tail tip. |

Pigmentation: band of pigment over gut, pair of spots between anus and caudal fin; few spots on ventral notochord tip. Sequence of fin formation: dorsal (7.0-8.0 mm TL); at 8.0 mm, dorsal, caudal and anal fin rays are well differentiated. At 15.0 mm, young displays adult form. |
