Recorded from the Danum Valley, lower Segama and Kuamut headwaters. Most common cyprinid species around Danum Valley Field Centre, fond in all stream systems with slow-moving water, attaining high abundance in the absence of other species (schools of more than 200 individuals have been observed). Dispersal abilities very good, populations being established in stagnant roadside pools and above waterfalls, including substantial series of falls at Maliau Basin Conservation Area (Ref. 34011).
