Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 9 - 10; Radios blandos dorsales (total) : 25 - 28; Espinas anales: 3; Radios blandos anales: 28 - 31. Caudal fin broadly forked (Ref. 6885). Generally silvery overlaid lightly with a brassy cast; light green above; sides with a series of about 9 to 11 narrow vertical dark bars, posteriorly, broken and staggered along the lateral line; caudal and anal fins red (Ref. 6885).
