It is found in countries in the Mekong river basin in South-East Asian countries, such as Cambodia, Laos, Thailand, and Vietnam. It prefers clear, fast-moving streams and waterways with a rocky bottom and ample shade. It prefers tropical locations.

The Mekong Minnow feeds on algae on rock surface, as well as insect larvae. It is benthic because it lives mainly on the bottom of the stream.
