简单描述
检索表 | 型态特徵 | 形态测量图
Snout truncated. Anal fin much shorter than head length. Dorsal fin base very long. Vertical bars on body more conspicuous in adults, reduced to very short bars on the midline. Some populations have a dark band along the body, may be absent or diffuse on fish of other regions. Caudal fin bluish white on the margin, the proximal half is colorless and the intermediate area is darkened, especially in males. Distal half of dorsal fin yellow or orange; edge of first rays of anal fin orange or red, the black blotch sometimes absent. Bluish green highlights on iris, cheek and scales above pectoral fin (Ref.36880).
吻截形的。 臀鳍远短于头长。 背鳍基底非常长的。 在身体上的纵带更显着的当成鱼时, 在中联机缩小成非常短的横带。 一些族群有一个深色条纹沿着身体, 可能是没有或扩散开在其他区域的鱼上。 尾鳍蓝白色的在边缘上，近端的一半是无色的与中间的区域颜色较深, 尤其在雄性中。 末梢部一半的背鳍黄色或橘色的; 臀鳍的第一鳍条的边缘橘色或红色的, 黑色的斑块有时不存在。 在虹膜，颊与鳞片胸鳍上方上的蓝绿色的突出部分.(参考文献 36880)
Inhabits stagnant waters or currents of all velocities between 40-1250 m of elevation; mainly in waters of moderate flow in brooks and creeks at temperatures of 20-23°C. Feeds on terrestrial insects (Ref. 36880).
