At 6.5 mm, spinous dorsal fin not yete developed. Thick finfold is visible between the posterior part of the head and the enterior part of the second dorsal fin. Second dorsal fin rays 20. Anal fin rays 21. Caudal fin rays 18. At 20 mm, preanal myomeres 14, postanal myomere 20. Pigmentation: Pigmented spots (each one below each ray) line the base of the anal fin. At 8-13 mm, 2 pigmented spots are present at the anterior portion of the caudal peduncle, between the posterior ends of the dorsal and anal fins. In some larvae, two rows of chromatophores (one along the mid-dorsal line behind the dorsal fin and the other mid-ventrally behind the anal fin) are present, though this information requires verification. |
