Descripción breve
Claves de identificación | Morfología | Morfometría
Radios blandos anales: 11 - 12. Can be diagnosed by having the following characters: dark transversal bars on dorsum present; dark spots absent on the center of each body scale in some specimens; usually two, sometimes three or four midlateral dark blotches on body; angle of the dorsal and ventralmost radii of body scales between 110° and 180°; and cranial fontanel partially closed (Ref. 91907).
Body shape (shape guide): fusiform / normal.
Adults are found in schools of 10-50 specimens in deeper water. They feed on plants (Ref. 13371). Distinct pairs breed on densely grown weedy places (Ref. 205).
