簡短描述
型態特徵 | 形態測量圖
Anal fin almost as long as or longer than head length. Dorsal fin rays long and almost reach the base of the caudal fin, lacking a distance equal to or less than the eye diameter. Sides of the body with 10 - 12 dark bars and 3 or 4 series of spots which correspond to the longitudinal scale rows along the body. Dark caudal fin margin with a vertical series of short dark streaks a little closer to the base than to the posterior margin of the tail. Dorsal fin red-orange with black stripes on the base. Body gray with a tenuous pink or orange hue (Ref. 36880).
臀鰭幾乎與頭長等長或更長。 背鰭鰭條長的而且幾乎達到尾鰭基底, 沒有距離等於或小於眼直徑。 身體有 10- 的側邊 與 12條深色的橫帶與 3 或 4 斑點列一致的縱向的鱗片列沿著身體。 深色的尾鰭邊緣有一個垂直的成列短深色條紋稍微更靠近基底超過對尾部的後面的邊緣。 背鰭紅色-橘色的在基底上有黑色的斑紋。 身體灰色的有一朵稀薄的粉紅色或橘色的色。 (參考文獻 36880)
Inhabits stagnant waters or creeks with low current velocity between 35 and 620 m elevation; in temperatures from 21 to 37°C; swims in small groups over muddy bottoms. Feeds on terrestrial insects (Ref. 36880).
