簡短描述
檢索表 | 型態特徵 | 形態測量圖
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。 臀鰭遠短於頭長。 背鰭基底非常長的。 在身體上的縱帶更顯著的當成魚時, 在中線上縮小成非常短的橫帶。 一些族群有一個深色條紋沿著身體, 可能是沒有或擴散開在其他區域的魚上。 尾鰭藍白色的在邊緣上，近端的一半是無色的與中間的區域顏色較深, 尤其在雄性中。 末梢部一半的背鰭黃色或橘色的; 臀鰭的第一鰭條的邊緣橘色或紅色的, 黑色的斑塊有時不存在。 在虹膜，頰與鱗片胸鰭上方上的藍綠色的突出部分.(參考文獻 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).
