Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic; non-migratory. Tropical; 25°N - 10°N, 12°W - 5°E
Africa: a slow flowing creek near Samalofila, southwest of Bamako, and a locality east of Bougouni in southwestern Mali (Ref. 57259).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 4.0 cm TL male/unsexed; (Ref. 57259); 4.0 cm TL (female)
Dorsal spines (total): 0; Dorsal soft rays (total): 5 - 7; Anal spines: 0; Anal soft rays: 11 - 14. Diagnosis: small and slender ‘Lampeye’ species with rounded unpaired fins and low sexual dimorphism; dorsal fin with 5-7 rays, anal fin with 11-14 rays, displacement between dorsal and anal fins 1/9-12; scales on mid-lateral series 27-30 (Ref. 57259).
Colouration: Male colouration: body colour is pale olive-grey with a light blue iridescence on the sides and a white ventral area; the scales have narrow dark brown to black margins; unpaired fins are mainly pale green; the caudal fin has a grey to black edging to the upper and lower parts, and the dorsal fin displays a grey to black margin; the anal fin has a brown submarginal band; the ventral fins are green (Ref. 57259). Female colouration: the colour pattern is similar to that of the male but much less prominent; the bands in the unpaired fins are also much less distinct (Ref. 57259). Both sexes show a light blue to green reflection in the iris (Ref. 57259).
Found in schools, most commonly in the upper water layers (Ref. 57259). Not a seasonal killifish. Is easy to maintain in the aquarium (Ref. 27139).
