Walker’s Killi

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.

Tank Set-Up

This species is not often seen in the aquarium hobby, but checking with the American Killifish Association may be beneficial. The Walker’s Killi can be kept in conditions similar to other species of Killifish. The tank should be lined with dark substrate and decorated with areas of dense planting and driftwood. The water in a Walker’s Killi tank should be filtered through peat and the temperature should not be too high or it may shorten the lifespan of these fishes.

Feeding

These fish tend to accept quality flake foods but often prefer live and frozen foods. For optimum health and coloration, feed a varied diet of live/frozen foods such as brine shrimp, Daphnia, and bloodworms along with a good quality flake.

Breeding

Walker’s Killifish are “egg hangers” and can be spawned fairly easily in the home tank. A trio of two females and one male should be conditioned separatedly on live and frozen foods then introduced into a spawning tank full of soft, acidic water. After spawning, incubate the eggs in a peat moss-lined container filled with an inch or two of water. After 21 days the eggs should hatch and the fry may be fed brine shrimp or microworms.
