Fundulopanchax Walkeri

Datasheet

General Description

There are various populations of Fundulopanchax Walkeri species, some of which are endangered due to human development in Ghana and the Ivory Coast. Interestingly, this fish can exist as both an annual and non-annual species, adapting to breed in permanent and temporary water bodies. F. walkeri prefers cooler temperatures compared to other killifish species, with high temperatures shortening its lifespan significantly.

Aquarium Setup

For F. walkeri, a minimum tank size of 28 litres should be provided, with a dark substrate like peat moss. Create dense planting areas and wood pieces for cover, while using floating plants to diffuse light. Due to their jumping ability, ensure the tank has tight-fitting covers. Peat filtration is recommended, and water conditions of pH 6.0-7.0, hardness of 5-12 dH, and a temperature range of 20-23°C should be maintained.

Behaviour

Although F. walkeri can coexist in a community tank, it thrives better in a species-exclusive setup. Known to consume any fish that fits into its mouth, this species displays aggression above its size and prefers slightly cooler temperatures compared to many others.

Feeding and Diet

A diet of small live or frozen foods like daphnia or bloodworms is preferred for F. walkeri, though they can also accept high-quality flakes in some cases.

Reproduction & Dimorphism

Easily spawned, F. walkeri is termed an "egg hanger" and can be bred in small aquariums. Males are larger and more brightly colored. Water conditions should be soft and acidic, with a temperature of 73-75°F. Spawning media can include peat moss, spawning mops, or fine-leaved plants. Eggs are deposited on substrate or vegetation, with incubation options in water or on peat moss.

Habitat and Distribution

Found in small streams, swamps, and ponds within coastal rainforest and forested savanna areas, F. walkeri is native to Ghana and the Ivory Coast.
