; 淡水 底中水層性; pH range: 5.5 - 6.5; dH range: ? - 15. 熱帶; 22°C - 27°C (Ref. 13371); 8°N - 6°N
Asia: endemic to Sri Lanka. Occurs mainly at the south western wet zone, from the Kelani to the Gin basins. Range extends north of the Kelani, into the swamps around Gampaha (Attanagalu Oya) and northwards. Introduced into the Perdeniya Gardens in the Mahaweli basin and is well established between Gampola and Ginigathena (Sri Lanka).
亞洲: 斯里蘭卡的特有種。 主要地在西南方的濕區域,從 Kelani 到琴河流域生存。 範圍延伸 Kelani 北方, 進入沼澤之內 Gampaha(Attanagalu Oya) 與北方的周圍。 引入在 Mahaweli 流域的 Perdeniya 花園中了而且很好地在 Gampola 與 Ginigathena(斯里蘭卡) 之間被建立。

Yellow finned variety usually occurs in flowing water and stays close to the substrate (sand to boulders). Red finned variety inhabits slow flowing waters of marshes in the Kelani Valley foothills, associated with mud or silt bottoms. Forms medium sized shoals. Matures at 3 cm and spawns during rainy season (Ref. 6468). Feeds on green algae, plankton and detritus (Ref. 6469). Population with strongly bifurcate caudal fin from introduced Mahaweli stock (Ref. 6470).
鰭黃色的變種通常出現於流動的水中,而且停留接近底部 (沙子到大圓石) 。 鰭紅色的變種在 Kelani 山谷山麓小丘,被伴隨著的泥或淤泥底中居住於濕地的慢流動水域。 形成中等大小的淺灘。 在 3 公分時成熟而且在雨季的時候產卵。 (參考文獻 6468) 吃綠藻,浮游生物與碎屑。 (參考文獻 6469) 具有來自引入的 Mahaweli 分枝的強烈分叉尾鰭的族群.(參考文獻 6470)
