背棘 (总数) : 1; 背的软条 (总数) : 7; 臀棘: 1; 臀鳍软条: 6. This species is shares with T. truncata, presence of a large black axine starting from approximately mid-body with dorsal apex near dorsal-fin origin, ventral apex near pelvic-fin origin, and caudal apex near caudal-fin base. It differs from all its congeners in the following set of characters: a
steep sloping lateral head to pre-dorsal region (shared with T. espei, vs. a gentle sloping lateral profile from posterior of head to predorsal region for T. truncata, T. hengeli, T. somphongsi); terminal mouth (shared with all except truncata with a sub-superior mouth); caudal apex of axine
reaching caudal-fin base (shared with all except truncata with caudal apex not reaching); dorsal and ventral apices of axine originate near to both dorsal-fin and pelvic-fin origins (shared with truncata vs. dorsal apex starting up to 3 scale-width posterior to dorsal-fin origin and ventral apex starting two scale-width after pelvic-fin origin in espei, hengeli, while axine is reduced to thick black stripe in somphongsi); dorsal fin with distinct orange/red pigments shared with truncata, espei (vs. hengeli, somphongsi with almost hyaline dorsal fin) (Ref. 122370).
彩色斑纹淡红的，略带桃色的或橘色的身体有一条显着的黑色斑纹为了要有一个三角形的或孵化形状 , 从下方尾鳍基底的背鳍起点到中央而且通常前面地扩大。 不完全的侧线缩小成 6-9个孔了。 没有触须。 分枝的臀鳍鳍条,5.(参考文献 38434)
Inhabits forest streams (Ref. 13061). Found in primary peat swamps in larger than 100 fish (Ref. 57235). Feeds on worms, crustaceans and insects (Ref. 7020). Eggs spawned at the underside of broad leaves and similar structures (Ref. 38434). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539). Previously known as "Rasbora" but revised as separated genus by Kottelat & Witte (1999) (Ref. 57235).
栖息于森林溪流。 (参考文献 13061) 在大于 100个鱼中发现于初期的泥煤沼泽了。 (参考文献 57235) 吃蠕虫，甲壳动物与昆虫。 (参考文献 7020) 卵在宽树叶与相似的结构下面产卵了。 (参考文献 38434) 水族馆保持: 形成 5个或更多个体的群体; 水族馆最小体型 60 公分.(参考文献 51539) 先前知道如 " Rasbora" 但是校订依照分开了 Kottelat& Witte(1999) 的属.(参考文献 57235)
