About Clown Killifish

The Clown Killifish, also known as the Banded Panchax, is a tiny, colorful killifish perfect for nano aquariums. Males display striking vertical bands of blue, yellow, and red on their bodies and tails. Native to West Africa, these small fish stay under 2 inches and are peaceful community residents. They are egg-layers that prefer soft, acidic water and should be kept in pairs or small groups. Their brilliant colors and small size make them ideal for carefully scaped nano tanks with other micro fish.
