簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 7 - 9; 臀鰭軟條: 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).
身體非常深的。 尾鰭與大部分的在求偶的雄性上的臀鰭是鮮橘色的。 求偶的雄魚有一個鋸齒形或者新月狀-形狀斑塊深色的些微地與深色側面的條紋的後端分開了。 背鰭的前面鰭條在扁平的鰭達不到後面的鰭條的頂端。 (參考文獻 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).
殘枝或者根的周圍, 出現於縮減的水流, 在上懸的植物或一個上懸的坡下面, 或者偶然地在漂浮的殘礫下面在斷枝或 牛尾草 或 Vitis 藤的蔓生叢上面捕獲.(參考文獻 40813)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
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).
營養階層 (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref.

Fishing Vulnerability (Ref.
