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).
栖息于较大的河的下游。 自由游动的鱼种发现接近水表面。 夜行的, 加上活跃的在薄暮与破晓的时候。 吃较小的鱼。 藉着他的厚又钙化上颌骨触须与臀鳍的少数鳍条那是的第一个，雄鱼是可认识的融合, 支撑沿着鳍条的前缘到顶端的尿殖管.(参考文献 6868) 这一个鱼在鱼网中包含多数的捕获而且尤其在雨季的时候被捕获是它的生殖的时期。 在洪水区域中时常生存比较少量, 偏爱侵蚀区域在哪里它在大的数量中出现.(参考文献 27188)

50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00483 - 0.01247), b=3.02 (2.88 - 3.16), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
营养阶层 (Ref.
69278): 3.6 ±0.51 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
