Các tia vây lưng cứng (tổng cộng) : 0; Tia cứng vây hậu môn: 0. Diagnosis: A short and robust Aplocheilichthys species of relatively small size with rounded fins (Ref. 47311).
Colouration: The colour is quite variable in males (Ref. 47311). In general, the sides are an iridescent grass-green to blue-green; on the frontal part of the body and the back this may change to a golden green or bronze-green; the latter colour may cover the body entirely in some populations; the scales on the back and sides have narrow dark gray borders, which may be more distinct on scales along the mid-lateral line; at the upper end of the operculum, forward of the pectoral fins, is a black, vertical oblong marking (Ref. 47311). The colour of the unpaired fins is also variable and ranges from dark gray or almost black to grass-green or bronze; dark gray or red to red-brown margins may be present (Ref. 47311). Some populations may include specimens with orange-red fins, while in others the orange-red colour is limited to the margins of the unpaired fins (Ref. 47311). Females are light gray-brown to gray; very narrow, dark gray margins to the scales produce a faint reticulation on the sides which is best developed along the mid-lateral line, resulting in a faint longitudinal line in some cases; the ventral parts are silver; all fins are colourless (Ref. 47311). Both sexes show a silver reflection in the iris, the upper part being green in the male (Ref. 47311).
Body shape (shape guide): elongated.
Found in shallow parts of papyrus swamps of Lake Victoria; also found in river mouths, rice fields and ditches connected to lakes (Ref. 3788, 47311). Sexual maturity is reached at an age of about 6 months (Ref. 47311). Not a seasonal killifish (Ref. 27139).
