Schistura sexcauda

provided by wikipedia EN

Schistura sexcauda is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found in the basin of the Chao Phraya River in central Thailand where it has been recorded in streams with a moderate to fast current and in riffles, over substrates consisting of gravel to stone.[1] It is known to be raised in local subsistence fisheries and traded both nationally and internationally as an ornamental fish. [3]

Some authorities regard Schistura fowleriana as a synonym of this species.[4]

Etymology

The genus name Schistura refers to the fish's forked caudal fins, coming from the Greek schizein and oura meaning respectively "to divide" and "tail".[5] The species name sexcauda comes from Latin sex and cauda meaning "six" and "tail", referring to the six bar markings behind its dorsal fin.[6]
