Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 7 - 9; Anal spines: 0; Anal soft rays: 14 - 17. Diagnosis: Robust, fairly deep-bodied ‘Lampeye’ species with relatively long fins; dorsal fin with 7-9 rays, anal fin with 14-17 rays; displacement between dorsal and anal fins 1/7-9; scales on mid-lateral series 26-29 (Ref. 57259).
Colouration: Male colouration: overall body colour is a light olive-grey, with a distinct light blue iridescence on the sides, mainly on the frontal part of the back, between the upper operculum and the beginning of the dorsal fin; all scales have a distinct dark brown border, creating a strong reticulation on the sides; the dorsal and anal fins are yellow to orange-red, this colour intensifying towards the fin margins; red-brown spots, arranged in curved bands, are present in the posterior parts of these fins; the caudal fin is pale blue in the central part, grading to yellow or orange towards the margin; this fin also displays a large number of dark brown spots, arranged to form crescent-shaped crossbars (Ref. 57259). Female colouration: translucent grey in general body colour with a weak silver iridescence; the scales also have narrow brown borders, but this feature is less distinct than on the male; the unpaired fins are colourless (Ref. 57259). Both sexes have a distinct light blue-green reflecting spot in the upper part of the iris (Ref. 57259).
Found in quiet parts of brooks, small rivers and streams under gallery forest cover in the savannah of the Fouta Dialon (Ref. 7372, 57259). Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139).
