简单描述
检索表 | 型态特徵 | 形态测量图
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).
臀鳍几乎与头长等长或更长。 背鳍鳍条长的而且几乎达到尾鳍基底, 没有距离等于或小于眼直径。 身体有 10- 的侧边 与 12条深色的横带与 3 或 4 斑点列一致的纵向的鳞片列沿着身体。 深色的尾鳍边缘有一个垂直的成列短深色条纹稍微更靠近基底超过对尾部的后面的边缘。 背鳍红色-橘色的在基底上有黑色的斑纹。 身体灰色的有一朵稀薄的粉红色或橘色的色。 (参考文献 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).

营养阶层 (Ref.
69278): 3.5 ±0.50 se; based on food items.
回复力 (Ref.
