Comments: Found in lowland water courses with little current (Ref. 26100).  Also inhabits springs and stretches of streams with moderate current.  Most populations occur in small streams and are very sensitive to water abstraction and pollution (Ref. 59043). Feeds on invertebrates, plants (Ref. 26100) and small aquatic insects (Ref. 59043).  Threatened due to pollution, habitat destruction (Ref. 26100) and water abstraction (Ref. 59043).
