Description

The Mekong flying barb is a flying barb (Cyprinidae) from slow-flowing and still fresh water of the Mekong basin in Southeast Asia. The species grows to about 8 cm and has a slender, silvery body with a conspicuously long pair of barbels and large pectoral fins. As a social surface fish it swims in schools and snaps at insects falling on the water, larvae and small zooplankton; when threatened it can skim a short distance over the surface. The fish is harmless to humans.
