Killifish
Killifish – Colourful, Rare & Fascinating Freshwater Fish
At Wonderworld Aquarium & Pet Centre, our Killifish range features some of the most vibrant and unique freshwater fish available in NZ.
Known for their intense colours, patterned fins, and short but fascinating lifecycles, Killifish are a favourite among experienced aquarists and collectors. Many species are best kept in species tanks or carefully selected community aquariums.
Killifish prefer soft to moderately hard water, gentle flow, and secure lids as some species are skilled jumpers. Planted tanks with floating cover help them feel secure and display their best colours.
