The Gardneri killifish carries a striking orange-red body scattered with iridescent blue-green spots and banding, particularly vivid in mature males, making it one of the most colourful small fish covered in this entire series. It comes from Nigeria and Cameroon in West Africa and stays compact, reaching around five to six centimetres.
Unlike some killifish that live only a single season in the wild, the Gardneri killifish is generally treated as a non-annual species, meaning it does not rely on drying seasonal pools and can live a genuinely normal multi-year lifespan in a stable aquarium, making it considerably more approachable than the more specialised annual killifish some hobbyists associate with the group. In truth its wild behaviour sits somewhere on a spectrum, since populations in less stable West African habitats can behave more like seasonal spawners, but the captive-bred stock sold in the hobby consistently behaves as the easier, long-lived non-annual type.
A pair or small group does well in a tank of forty litres or more, with dense planting, floating cover and subdued lighting that echoes its shaded forest stream habitat. It tolerates a reasonable range of water conditions, including typical Indian tap water, though it does best in a stable, well-established tank.
A tight-fitting lid is essential, since like most killifish it is an accomplished jumper, particularly when startled or displaying.
A diet of small live or frozen foods such as bloodworm, brine shrimp and daphnia suits it best, alongside good-quality micro pellets once the fish are settled. It can be reluctant to take dry food exclusively, so keeping some live or frozen options on hand matters.
Males can be territorial towards each other, particularly in a small tank, so a single male with several females, or a larger tank with more swimming room for multiple males, keeps behaviour calmer.

Flushing a fish, whether dead or simply unwanted, down the toilet is a habit many Indian households have inherited without questioning it, and it carries real risks that are worth understanding.
