deskripsi pendek Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)): 15 - 17; duri punggung lunak (Keseluruhan (total)): 11-14; Duri dubur 3; Sirip dubur lunak: 9 - 12; vertebrata, bertulang belakang: 30 - 32. Scales on cheek in 2-3 rows. Caudal scales variable, not on the inter-radial membranes except at the base; never stiffening the fin. Genital papilla large and tuberculate or scalloped, tasseled in breeding males. Generally lighter or darker olive-green.
