Though Walker’s Killis can be found in many different populations throughout Africa, it has become threatened or extinct in some areas due to human development. These fish are native to Ghana and the Ivory Coast where they tend to inhabit small streams, ponds and swamps in both the rainforest and forested areas of the savannah. These Killifish are both annual and non-annual, living in both temporary and permanent bodies of water. Males of the species often have a greenish sheen to their bodies and exhibit dark spotting on the body and caudal fin. The fins of male Walker’s Killis are orange in color with black edges. Females of the species are typically drab in coloration, often light brown with faint dark brown spots and colorless fins.
