Maturity: Lm ? range ? - ? cm
Max length : 8.5 cm SL 雄鱼/尚未辨别雌雄; (Ref. 122736); 最大体重: 7.70 g (Ref. 122736)
背的软条 (总数) : 11. This species differs from other congeners, except intermedia and dichroura by the following combination of characters: presence of a black posterior margin on each caudal-fin lobe, and presence of a black lozenge-shaped pigment blotch on the caudal peduncle that extends to the posterior limit of the median caudal-fin rays; the short 7 gill rakers on the upper limb of the first gill arch distinguish bonita from the 2 similar species that possess 10 elongate gill rakers on the upper limb an d18 on the lower limb of the first gill arch (Ref. 51265).
这种与其他同类不同, 除了 媒介物 与 dichroura 以外藉由跟随组合特征: 有在每个尾鳍叶上的一个黑色的后缘, 而且有一个黑色的菱形-在延伸到中央尾鳍鳍条的后面的限制的尾梗上的形状有颜色斑块; 在第一个鳃弓的上边缘上的短人 7个鳃耙区别 bonita 从在第一个鳃弓的下面肢翼上在上边缘上持有 10个细长的鳃耙 d 18 的 2个相似的种。 (参考文献 51265)
Collected in marginal backwaters with low current speeds (about 0.1 m/sec) in up to 1 meter depth. Occurs primarily near the water surface, swimming in schools up to 10-30 individuals. Stomach contents and observations indicate that this species feeds mainly on terrestrial insects (dipterans and coleopterans) from the surrounding riparian forest. The insects are captured via surface picking and drift feeding (Ref. 51265).
在边缘的洄水区中的向上到 1 公尺深度中收集了水流量小的地方速度 (大约 0.1 公尺/秒) 。 主要地在水面的附近生存,在鱼群向上到 10-30个个体中游泳。 胃内含物与观察指出这种主要捕食陆栖的昆虫 (双翅类昆虫与鞘翅目) 从周围的河岸森林。 昆虫经由表面的采集与漂流物进食被捕获。 (参考文献 51265)
