Schistura cataracta
Introduction '''''Schistura cataracta''''' is a species of ray-finned fish in the stone loach genus ''Schistura''. It occurs in the Nam Theun and Nam Gnouang, in the Mekong basin of Laos. It prefers stretches of rivers with fast current and a stony or rocky substrate, but it does occasionally occur over gravel or sandy substrates. It can also be found in reservoirs, albeit at low densities and dams are the biggest threat to this species.
