Maturity: Lm ? range ? - ? cm
Max length : 27.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 26147)
Inhabits lower courses of the larger rivers. Free swimming species found near the surface. Nocturnal, plus active during dusk and dawn. Feeds on smaller fish. The male is recognizable by his thick, ossified maxillary barbels and by the first few rays of the anal fin which are fused, supporting the urogenyla tube that runs along the anterior border to the tip of the rays (Ref. 6868). This fish comprises the majority of the catches in the fish nets and is especially captured during the rainy season which is its reproductive period. Occurs less frequently in flood zones, prefers eroded zones where it appears in large numbers (Ref. 27188).
棲息於較大的河的下游。 自由游動的魚種發現接近水表面。 夜行的, 加上活躍的在薄暮與破曉的時候。 吃較小的魚。 藉著他的厚又鈣化上頜骨觸鬚與臀鰭的少數鰭條那是的第一個，雄魚是可認識的融合, 支撐沿著鰭條的前緣到頂端的尿殖管.(參考文獻 6868) 這一個魚在魚網中包含多數的捕獲而且尤其在雨季的時候被捕獲是它的生殖的時期。 在洪水區域中時常生存比較少量, 偏愛侵蝕區域在那裡它在大的數量中出現.(參考文獻 27188)
