Distinguished from all its congeners in Balkan Peninsula by the combination of the following characters: small black spot on opercle and upper third of flank, ocellated red spots on whole flank; body depth 19-23% SL; 16-18 gill rakers; preanal length 72-75% SL (Ref. 59043).
Found in streams. Believed to be originally an inhabitant of lakes entering streams to spawn, then returning to lake. Habitat modifications and water abstraction have interrupted the lower course of most streams and distribution is confined to headwaters, possibly to two streams only. Spawns in November (Ref. 59043).
