簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 11; 臀鰭軟條: 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，與所有的其他同類區分了,用它的紅色尾鰭與呈綠色-銀色的身體。 有別於所有的其他 Creatochanes, 包括 B. colaroja, 藉由跟隨組合特徵: 顎骨的在後部延長不達到垂直的經過關節在第二個之間與第三眶下的; 第三眶下的不腹地連絡前鰓蓋骨或在突出部位上; 17-19個 circumdorsal 鱗片; 沒有肱骨的標誌; 沒有尾鰭眼狀斑; 臀鰭有顏色密集的但是侷限於鰭條的邊緣, 不形成條紋; 18-19, 很少地 20個尾前椎; 臀鰭在 18-第 19個椎體下面開始, 很少地 20; 背鰭開始在上面第 10, 很少地第 11個椎體; 頰缺乏有顏色的顯著斑塊 ; 尾鰭葉長度相等.(參考文獻 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).
在生根脈管的 Podostemonaceae 的密集臺子之中的湍急水流與急流中出現於大的河棲息地, 以及在流動的小溪中。 也在沙子，礫石與岩石底部之上居住於小的溪流，急流，海灣與洄水區。 (參考文獻 47228)
