Morphology | Morphometrics
soft rays: 10 - 11. Body moderately elongated (Ref. 57144). Preorbital length 0.9-1.3 in eye-diameter (Ref. 57144). Dorsal fin inserted before origin of anal fin, on the same axis, with 7-8 (rarely 9) branched dorsal-fin rays (Ref. 57144). A long and narrow caudal peduncle, its length 1.7-2.0 in body least depth (Ref. 57144). Body pigmentation of live males a profusely mottled blue and silver, not forming vertical bars; females without conspicuous black spots, except a spot at the junction of the caudal peduncle and central caudal fin rays (Ref. 57144).
Africa: Algeria (Ref. 57144).
This species could be considered as critically endangered following IUCN criteria (Ref. 57144). Excessive ground water withdrawal for agricultural purposes, the drying of wetlands, and water pollution are, along with the introduced Gambusia, the major threats to the survival of this species (Ref. 57144).
