Pectoral fin enlarged. No crest on the nape. At 3 mm, lower lobe of the caudal fin is irregularly shaped. Body is laterally compressed at this stage. At 9 mm, body is dorsoventrally flattened and at times cylindrical. Head is prominently depressed dorsoventrally. Caudal fin almost oval in shape. First dorsal fin has 4 spines, second dorsal fin has 9-10 rays. Preoperculum process comprised with a forward-directed spine and a posteriorly-directed spine with 4 lateral processes are visible. Pigmentation: At 3 mm, pigmentation prominent along the mid-lateral line from the post-orbital region also ventrally. A pigmented band present along the ventral portion of the operculum up to the posterior tip of the pectoral fin and borders the ventral side of the myomeres. At 9 mm, the dorsal region of the body has 4-5 bands of pigments. |
