Short description

Anal spines: 1; Anal soft rays: 9 - 11; Vertebrae: 30 - 31. Body pale, with long vertical stripes in both sexes, some over 2/3 body depth; perianal organ small, less than half length of pelvic disc; pelvic anterior membrane depth about half pelvic spine length in ventral midline; body with well spaced scales in single series along lateral midline, and otherwise naked except on caudal peduncle and side of anterior abdomen; typical D2 I/10-11; interorbit with two transverse rows of sensory papillae.

With a mature female at 18 mm SL, this is the smallest European freshwater fish. Found at the mouth of tributary streams. Has been observed in small shoals near the surface, over open areas of gravel or stones. Feeds on invertebrates. Spawns from February to May. Is threatened due to water abstraction and pollution (Ref. 26100).
