Distinguished from congeners in Mediterranean basin by having the following combination of characters: 9-13 parr marks in adults; caudal fin slightly emarginate; 20-60 small ocellated spots on flank (smaller than eye), some black, some brownish red (Ref. 59043).
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).
