简单描述
型态特徵 | 形态测量图
背的软条 (总数): 11; 臀鳍软条: 26 - 30; 脊椎骨: 40 - 42. Distinguished from all other congeners, except B. colaroja, by its red caudal fin and greenish-silver body. Differs from all other Creatochanes, including B. colaroja, by the following combination of characters: posterior extension of maxilla not reaching vertical through articulation between second and third infraorbital; third infraorbital not contacting preopercle ventrally or at angle; 17-19 circumdorsal scales; no humeral mark; no caudal fin ocellus; anal fin pigment dense but restricted to margins of fin rays, not forming band; 18-19, rarely 20 precaudal vertebrae; anal fin originating under 18-19th centrum, rarely 20; dorsal fin originating above 10th, rarely 11th centrum; cheeks absence of conspicuous blotch of pigment ; caudal fin lobes equal in length (Ref. 47228).
除了 B. colaroja 以外，与所有的其他同类区分了,用它的红色尾鳍与呈绿色-银色的身体。 有别于所有的其他 Creatochanes, 包括 B. colaroja, 藉由跟随组合特徵: 颚骨的在后部延长不达到垂直的经过关节在第二个之间与第三眶下的; 第三眶下的不腹地连络前鳃盖骨或在突出部位上; 17-19个 circumdorsal 鳞片; 没有肱骨的标志; 没有尾鳍眼状斑; 臀鳍有颜色密集的但是局限于鳍条的边缘, 不形成条纹; 18-19, 很少地 20个尾前椎; 臀鳍在 18-第 19个椎体下面开始, 很少地 20; 背鳍开始在上面第 10, 很少地第 11个椎体; 颊缺乏有颜色的显着斑块 ; 尾鳍叶长度相等.(参考文献 47228)
Occurs in large river habitats in swift current and in rapids among dense stands of the rooted vascular Podostemonaceae, as wells as in small streams with current. Also inhabits small streams, rapids, bays and backwaters over sand, gravel and rocky bottoms (Ref. 47228).
在生根脉管的 Podostemonaceae 的密集台子之中的湍急水流与急流中出现于大的河栖息地, 以及在流动的小溪中。 也在沙子，砾石与岩石底部之上居住于小的溪流，急流，海湾与洄水区。 (参考文献 47228)
