生態學
; 淡水 底中水層性; pH range: 6.0 - 6.5; dH range: 5 - 12. 熱帶; 22°C - 26°C (Ref. 1672); 8°N - 6°N
Asia: restricted to forest streams from the Kelani to Nilwala basins in Sri Lanka. It occurs in hilly areas up to about 300 m elevation. The brightly colored population introduced to Mahaweli at Ginigathena, Sri Lanka are said to have diminished in number due to the aquarium export trade.
亞洲: 侷限於在斯里蘭卡森林溪流從 Kelani 到 Nilwala 流域了。 它出現於中多丘陵的區域達到大約 300 公尺海拔。 色彩鮮豔的族群引進了在 Ginigathena 的 Mahaweli, 斯里蘭卡據說已經數量減少由於水族館輸出貿易。

Inhabits clear, cool, shady streams in forested areas, on gravel or sand substrate. Sometimes found in pools of quiet water in the margins of clear streams and rivers (Ref. 6471). Bred in captivity. Spawns in shallow water among marginal weeds. Eggs (>100) hatch in 1-2 days; fry are free-swimming after 24 h (Ref. 6702). Feeds mainly on filamentous algae and detritus (Ref. 6703). Males brightly colored and with darker fins. Popular aquarium fish. Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 80 cm (Ref. 51539).
在礫石或沙子底部上, 在森林區域中棲息於清澈寒冷又暗的溪流。 有時在清澈溪流與河的邊緣中發現於靜止的水域的水池。 (參考文獻 6471) 在繁殖場中飼養了。 產卵在雜草叢之中的淺水區。 卵 (>100) 在 1-2 數天中孵化; 魚苗在 24 h 之後是游離於水中。 (參考文獻 6702) 主要吃菌絲藻與碎屑。 (參考文獻 6703) 雄性色彩鮮豔的而且有較深色的鰭。 受歡迎的水族館魚。 水族館保持: 形成 5個或更多個體的群體; 水族館最小體型 80 公分.(參考文獻 51539)
