During the dry season the fish live in the clear water of the main stream and during the rainy season they migrate to the flood plains and flooded gallery forests . In the middle reaches of the Mekong, Cosmochilus harmandi has its habitat until the water level rises. The nutritional basis of Cosmochilus harmandi has not yet been fully explored. Due to the subordinate mouth shape, it is assumed that the species feeds on plant roots on the fine-grained water bed.
