Maturity: Lm ? range ? - ? cm
Max length : 30.0 cm TL オス/雌雄の選別がない; (Ref. 111518); 最大公表体重: 255.00 g (Ref. 111518)
背面の脊椎 (合計) : 2; 背鰭 (合計) : 9; 肛門の骨: 3 - 5; 臀鰭: 21 - 27. Possesses a humeral spot shaped as an oval or inverted teardrop, occupying not less than a quarter of the height of the body; caudal peduncle with a black spot covering between one third and almost the totality of its depth (Ref. 52916).
Attains a length of around 20 cm. As indicated by its dentition and body form, it is a formidable predator which feeds exclusively on fish. A ubiquitous species, but frequently found throughout the length of waters with moderate flow. Reproduction begins with the onset of the rainy season (Ref. 12225).
