|Population:||D. pathirana is reported to be numerous within its limited range (Pethiyagoda 1994).|
|Habitat and Ecology:||D. pathirana is a pelagic species that occurs in swift flowing streams, with pebble or boulder substrates. It has not been found in silted rivulets flowing into the mainstream. It forms groups of 3-5 individuals slowly moving near the surface.|
D. pathirana is threatened by pressure from shade loss and agricultural effluents (Pethiyagoda 1994).
During the past two centuries, nearly all the natural forests in this eco-region have been cleared for tea, rubber, and coconut plantations, rice paddies, and human settlements (WWF 2001).
|Conservation Actions:||It is not known if there are any conservation measures in place or needed.|
