Killifish
Also known as: Fundulopanchax gardneri
Fundulopanchax gardneri, commonly known as Gardner's killifish, is a small, colorful freshwater fish native to West Africa. The Killifish originates from West Africa, specifically Nigeria and Cameroon, inhabiting slow-moving streams, swamps, and seasonal floodplains with dense vegetation., reaches Adult size: 5-6 cm in captivity, typically lives 2-3 years, and is kept at 22-26°C (72-79°F). Individual fish vary, so treat this as a general guide rather than a guarantee.

About the Killifish
Fundulopanchax gardneri, commonly known as Gardner's killifish, is a small, colorful freshwater fish native to West Africa. Males display vibrant blue-green bodies with red spots and elongated fins, while females are more subdued in coloration. This species is adapted to seasonal habitats and can survive temporary drying of its environment through egg diapause. In captivity, it is valued for its striking appearance and interesting breeding behavior.
Lifespan and health
With proper care, Fundulopanchax gardneri typically lives 2-3 years in captivity, though some individuals may reach up to 4 years under optimal conditions; their lifespan is naturally short due to their annual life cycle in the wild, where they hatch, mature, breed, and die within a single rainy season. Common health issues include fungal infections (often from poor water quality or injury), parasitic infestations like ich (white spot disease), and swim bladder disorders caused by overfeeding or bacterial infection; maintaining stable water parameters, providing a varied diet, and quarantining new fish are key preventive measures.

Care and tank setup
Tank setup should include a densely planted aquarium with fine-leaved plants like Java moss or spawning mops to provide cover and breeding sites; use a dark substrate and low lighting to mimic natural conditions. A gentle sponge filter is ideal to avoid strong currents, and the tank should be covered as these fish are known jumpers. Water parameters must be maintained within the specified range with weekly 25% water changes to prevent nitrate buildup; avoid sudden changes in temperature or chemistry. Feed small amounts 2-3 times daily, offering live or frozen foods as the primary diet with occasional dry food supplementation; remove uneaten food promptly to maintain water quality.
