Second dorsal fin with 9 segmented rays; usually 15 pectoral fin rays; lateral scales extend dorsal to pectoral base, usually 33-36; belly scaled close to pelvic disc; males with first dorsal fin higher than second dorsal fin, spines not filamentous; predorsal midline with 9-17 cycloid scales; males blackish, 5 or 6 bars between second dorsal and anal fins; and females with midlateral band straight with blotchy patches on caudal peduncle.
具有 9个分段的鳍条第二背鳍鳍; 通常 15个胸鳍鳍条; 侧面的鳞片延伸背部的对胸鳍基底, 通常 33-36; 腹面覆有鳞片的接近腹鳍体盘; 雄性有比第二背鳍鳍高的第一背鳍, 不丝状的棘; 用 9-17个圆形的鳞片前背的中线; 雄性黑色的, 在第二背鳍与臀鳍之间的 5 或 6条横带; 而雌鱼有侧面中央的条纹笔直的有到处有污点的区块在尾梗上。
The species is found in coastal steams, in clear and oxygen rich water, in the lower course of rivers, up to 50 m in altitude. It prefers rocky substrates, with boulders and pebbles, and slow to medium currents (pools). It feeds on algae and small invertebrates, scraping them of the surface of the rocks. The species is amphidromous. After the reproduction in freshwater, larvae go at sea where they undergo a planktonic life for several months (Ref. 87781). Inhabits large and quite streams, preferring pools and backwater areas. (Ref. 26040).
栖息于大的与相当溪流, 偏爱水池与回流水区域。

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
