Gardner’s Splendid Carp (Fundulopanchax gardneri)

24 October 2026

Gardner’s splendid carp is a small West African killifish valued for its iridescent body, red markings and patterned fins. The supplied image appears to show a brightly colored male, while the source identifies a pair; exact locality form and sex of every fish cannot be confirmed from the available evidence. It is generally peaceful, though males may spar, and it is best kept in a covered, mature aquarium with gentle flow, subdued lighting and abundant plant cover.

Gardner’s Splendid Carp (Fundulopanchax gardneri)

Taxonomy and identification

The accepted scientific name is Fundulopanchax gardneri. It belongs to the family Nothobranchiidae and is commonly called Gardner’s killifish or Gardner’s splendid carp. The species includes geographically distinct populations and aquarium strains, so color and fin pattern can vary. The image is consistent with a male Gardner’s killifish, but locality form and the sex of the second fish cannot be verified.

Distribution and habitat

Fundulopanchax gardneri is native to parts of West Africa, especially freshwater habitats in Nigeria and adjacent areas of Cameroon. It inhabits small streams, forest pools, marshes and temporary or slow-moving waters, where vegetation and leaf litter provide cover. Local populations may differ in coloration and water preferences; captive fish should be acclimated gradually rather than exposed to abrupt changes.

Behavior and social needs

This species is usually peaceful toward similarly sized fish, but males can display and nip at one another, particularly in cramped quarters or when competing for females. Keep a pair or a small group with more females than males when possible, and provide dense plants, floating cover, caves or wood for retreats. A secure lid is essential because killifish can jump.

Aquarium setup and tank size

A mature aquarium of about 40 litres is a practical minimum for a pair or small group, with a larger footprint preferred for community housing. Use gentle filtration, stable biological filtration and subdued light, with plants such as Java moss, Anubias or floating vegetation. Leave some open swimming space but break sight lines with vegetation. Avoid strong currents and maintain excellent water quality.

Water parameters

Provide soft to moderately hard, clean water around 20–24 °C and pH 6.0–7.5. Stability is more important than pursuing a precise number, particularly for captive-bred fish. Regular partial water changes, careful acclimation and avoidance of overcrowding help prevent stress. Keep dissolved oxygen adequate without creating a turbulent current.

Diet

Offer a varied carnivorous diet. Suitable foods include appropriately sized frozen or live brine shrimp, daphnia, mosquito larvae and bloodworms, supplemented with a good-quality small pellet or flake where accepted. Feed small portions once or twice daily and remove uneaten food. Live and frozen foods are especially useful when conditioning adults for spawning.

Compatibility

Choose calm tank mates that are too large to swallow but not large or boisterous enough to outcompete or intimidate them. Small peaceful tetras, rasboras, smaller Corydoras and other gentle community fish may work in a suitably spacious, planted aquarium. Avoid fin-nipping species, aggressive fish and very active feeders. Do not mix different Fundulopanchax forms for breeding if maintaining locality lines matters.

Breeding

Gardner’s killifish is a plant- or mop-spawning species rather than a strict annual killifish. Provide a spawning mop, Java moss or fine-leaved plants, and condition the adults with live or frozen foods. The female deposits adhesive eggs among the fibers, often with the male nearby. Remove the mop or transfer eggs to a separate rearing container to improve survival, because adults may eat eggs and fry.

Eggs and fry

Incubation time varies with temperature and handling, commonly taking roughly two to three weeks in suitable conditions. Inspect eggs and remove any that turn opaque or fungus-covered. Newly hatched fry require very small foods such as infusoria or commercially prepared first foods, followed by newly hatched brine shrimp as they grow. Use gentle filtration and frequent small water changes in the rearing container.
