Stone loach.jpg

The stone loach (Barbatula barbatula) is a species of fresh water ray-finned fish in the Nemacheilidae family. It is one of seventeen species in the genus Barbatula. Stone loaches live amongst the gravel and stones of fast flowing water where they can search for food. The most distinctive feature of this 14 cm fish is the presence of barbels around the bottom jaw, which they use to detect their invertebrate prey. The body is a mixture of brown, green and yellow.
