The yolk-sac is largely absorbed by 3.5 mm TL. Pigmentation: After 6 mm TL, a single melanophore becomes obvious ventrally and immediately anterior to the cleithrum, and a pair of melanophores appears ventrally and immediately posterior to the cleithrum. A fine mid-ventral line of melanophores is visible along the hindmost two-thirds of the gut. |

Anterior migration of the anus and the dorsal and anal fins is noticeable at 17 mm TL. Scalation first appears along the lateral line at 26 mm TL and is complete by 35-40 mm TL. Sequence of fin development: caudal (3 mm TL); pectoral (3 mm TL); dorsal (7 mm TL); anal (11 mm TL); pelvic (16 mm TL). |
