Rocket / Clown Killifish

Looking for a colorful, little fish that stays in the upper third of your nano aquarium? Say hello to the Rocket / Clown Killifish Epiplatys annulatus, also known as the clown killi, rocket killifish, and banded panchax. These common names come from the alternating vertical bands of dark brown and tannish-yellow on its body and the vibrant, flame-like tail that males possess. While adult killies can reach up to 1.4 inches (3.5 cm), most of the fish sold at stores are juveniles around 0.5 inch long and won’t display their true red, yellow, blue, and orange colors until you bring them home and raise them to maturity.
