Probably restricted to the Ganges and Brahmaputra River basins in Nepal, India and Bangladesh with apparent occurences in Thailand, Myanmar and the Western Ghats mountains in southern India likely to represent undescribed species. The species was described from the Kosi River, a major Ganges tributary, and the speciens in our images were collected from Ghoti Ganga Creek, a northern tributary of the Ganges.

Best kept in a well-decorated set-up with aquatic vegetation and woody structures. The addition of some floating plants to diffuse the light entering the aquarium also seems to be appreciated and the addition of dried leaf litter can add a natural feel. Filtration, or at least water flow, should be relatively gentle, and use a soft substrate if possible since Oreichthys species have miniscule sensory bristles on the lower jaw which are used when foraging..
