Gardneri Killifish (Fundulopanchax gardneri) are hardy, colorful killifish that thrive in well-planted tanks with soft, slightly acidic to neutral water (pH 6.0–7.0) and temperatures between 72–78°F (22–26°C). They prefer subdued lighting and plenty of hiding places like plants and leaf litter. These peaceful fish do best in pairs or small groups and enjoy a diet of high-quality live or frozen foods such as bloodworms, brine shrimp, and daphnia, complemented with flakes or pellets. Regular water changes and good filtration help maintain water quality, supporting their active and vibrant nature.
