简单描述
检索表 | 型态特徵 | 形态测量图
背的软条 (总数) : 7 - 9; 臀鳍软条: 8 - 11; 脊椎骨: 36 - 38. Body very deep. Caudal fin and most of the anal fin on nuptial males are bright orange. Nuptial males have a chevron or lunate-shaped blotch of dark pigment slightly separated from the posterior end of the dark lateral band. Anterior rays of dorsal fin fall short of the tips of the posterior rays in the depressed fin (Ref. 40813).
身体非常深的。 尾鳍与大部分的在求偶的雄性上的臀鳍是鲜橘色的。 求偶的雄鱼有一个锯齿形或者新月状-形状斑块深色的些微地与深色侧面的条纹的后端分开了。 背鳍的前面鳍条在扁平的鳍达不到后面的鳍条的顶端。 (参考文献 40813)
Inhabits sand-bottomed and silt-bottomed pools and runs of headwaters, creeks and small rivers, usually along undercut banks and debris (Ref. 86798). Occurs in reduced current, under overhanging vegetation or an overhanging bank, around stumps or roots, or occasionally under floating debris caught on snags or trailing brush of Smilax or Vitis vines (Ref. 40813).
残枝或者根的周围, 出现于缩减的水流, 在上悬的植物或一个上悬的坡下面, 或者偶然地在漂浮的残砾下面在断枝或 牛尾草 或 Vitis 藤的蔓生丛上面捕获.(参考文献 40813)

50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00376 - 0.01926), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
