Comments: Inhabits streams in hilly areas and lowland in karstic resurgences.  Occurs in clear waters around 10-20° C, usually with dense subaquatic vegetation.  Feeds mainly on aquatic insects.  Spawns on gravel bottom in shallow water.  Attains a maximum size of up to about 40 cm SL.  Threatened due to water abstraction, overfishing and stocking of non-native trouts (Ref. 59043).
