Ecologia
; acqua dolce benthopelagico; pH range: 6.0 - 6.5; dH range: 5 - 12. Tropical; 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.
