Morphology | Morphometrics
soft rays: 11 - 14. Diagnosis: Small and slender ‘Lampeye’ species with rounded fins and low sexual dimorphism; dorsal fin with 6-9 rays, anal fin with 11-14 rays, displacement between dorsal and anal fins 1/8-11; scales on mid-lateral series 27-29 (+3) (Ref. 57259).
Colouration: Male colouration: overall body colour is pale yellow-grey to silver; the scales have narrow dark grey borders, producing a reticulated appearance; the lower lip is also dark grey; the opercle and sides show a distinct light blue iridescence; immediately behind the origin of the pectoral fins there is a vertically orientated oblong grey patch; the unpaired fins are pale yellow, becoming darker distally and ending in a dark grey to almost black margin; the caudal fin has some small dark grey spots, arranged in crescent-shaped crossbars (Ref. 57259). Female colouration: the body is an overall pale yellow-grey, with a silver iridescence on the frontal parts of the sides and the abdomen; the scales have faint dark grey borders, producing a weak reticulation; all fins are colourless (Ref. 57259). Both sexes show a silver reflection and a light blue spot in the upper part of the iris (Ref. 57259).
Found in small savannah streams (Ref. 57259). Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139).
