Mature males characterized by an extended ray on the first dorsal fin which is very long and overlaps the second dorsal fin when folded; courting male can appear turquoise to nearly black, with two "racing" stripes along the length of the body; females and juveniles normally mottled brown to gray-green; both sexes turn black when disturbed (Ref. 44091).
成熟的雄鱼在第一背鳍上特徵为一个扩大的鳍条是非常长的与重叠第二个背鳍当摺叠; 追求雄鱼能显得蓝绿色的到几乎黑色, 有两个 " 竞赛 " 斑纹沿着体长; 母鱼与稚鱼通常褐色班点对灰色-绿色; 两性变黑色的当被惊扰时。 (参考文献 44091)
Benthic in lower and middle reaches of streams (Ref. 58302). Adults inhabit mountainous streams. Are well adapted to exist in swiftly-flowing basalt-bottomed stream habitat (Ref. 26461). Presence of these species signify water of good water quality (Ref. 44091). Adults are primarily herbivorous, scraping algae off rocks, while the larvae are omnivorous; occasionally caught with nets ('upena), usually after being stupefied with native plants (e.g. hola and ahuhu), a process requiring partial diversion of the stream to reduce water flow; particularly prized in July and August when the females are gravid (Ref. 44091).
栖息于多山的溪流。 很好地被适应存在在很快地-流动的玄武岩底部的水流栖息地.(参考文献 26461) 出现这种象徵好水质的水.(参考文献 44091) 成鱼主要食草,啃食藻类外海的岩石, 然而仔鱼是杂食性的; 以网 ('upena) 偶而捕获, 通常在与原生的植物 (例如 hola 与 ahuhu) 一起使麻醉之后, 一个突起跟缩小的水水流需要水流的部分转移; 特别地在雌性是怀孕的七月与八月珍视。 (参考文献 44091)
