背面の脊椎 (合計) : 0; 背鰭 (合計) : 8 - 10; 肛門の骨: 0; 臀鰭: 15 - 17. Diagnosis: Larger-sized ‘Lampeye’ species; males usually with an extension at the upper corner of the caudal fin; sometimes with extended rays in the unpaired fins; ventral fins inserted distinctly behind pectorals; dorsal fin with 8-10 rays; anal fin with 15-17 rays; scales on mid-lateral series 27-33 (Ref. 57259).
Colouration: Male colouration: variable in colouration; basic colour light grey to light olive, dorsal area darker, ventral area light to almost white; on the sides strong light blue-green to light blue reflections, not arranged in bands, but covering the entire sides; the unpaired fins may vary from colourless, through pale blue to orange or pink, sometimes provided with red spots; the margins at the unpaired fins are usually red or pink, but sometimes black; a white outer margin may be present in the lower caudal fin; the caudal fin extensions are usually white (Ref. 57259). Female colouration: pale, semi-transparent grey or olive; some pale silvery reflections may be present on the sides; the fins are all colourless (Ref. 57259). Both sexes show an orange reflective spot in the upper part of the eye iris (Ref. 57259).
Body shape (shape guide): fusiform / normal.
Found in small rivers and brooks under forest cover and in the forested savannah on soils of basal origin; usually
swimming in schools in the streaming parts of the creeks (Ref. 57259). Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139).
