Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 9.0, range 9 - ? cm
Max length : 21.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 4833)
背棘 (總數): 1; 背的軟條 (總數): 6-7; 臀棘 0; 臀鰭軟條: 12 - 13; 脊椎骨: 31 - 37. Body elongate and slightly compressed. Maxillary barbels extending beyond the pelvic fins, often to the end of the anal fin. Dorsal spine weak, finely serrated on its inner edge. Adipose fin small, inserted much behind rayed dorsal fin but anterior to the anal fin. Color in life varies with age; generally delicate gray-silvery to shining golden, with several (about 5) pale blue or dark brown to deep black longitudinal on side. A narrow dusky spot often present on the shoulder. The fins glass, with dark tips (Ref. 4792).
細長的身體與些微扁長形。 上頜骨觸鬚延伸超過腹鰭, 時常到臀鰭末端。 背棘弱的, 細鋸齒狀的在它內緣。 脂鰭小的, 插入在有鰭條的背鰭的很後面但是位於臀鰭前。 顏色活著時隨著年齡改變; 通常嬌弱的灰色-銀色到閃爍金的, 有一些 (大約 5) 藍灰色或深褐色的到深黑色的縱向在側邊上。 一個狹窄的暗色斑點時常位於肩之上。 鰭玻璃, 與深色的末端.(參考文獻 4792)
Facultative air-breathing (Ref. 126274); Adults inhabit standing and flowing waters. Usually found among marginal vegetation in lakes and swamps with a mud substrate. Feed on plants, shrimps, insects, mollusks and fish (Ref. 6028). Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).
成魚棲息於靜止及流動的水域。 在湖中通常發現於雜草叢中,而且沼澤具有一個泥底部。 吃植物, 蝦,昆蟲,軟體動物與魚.(參考文獻 6028) 卵生的, 明顯的成對可能地像其他的相同該科的成員.(參考文獻 205)
