The Halfmoon Koi Female Betta (Betta splendens) is a stunning domestic Betta combining the elegant halfmoon tail form with the highly sought-after Koi colouration — a vivid patchwork of red, orange, black, and white that mimics the markings of a traditional Japanese Koi carp. Female Bettas are smaller and more community-friendly than males, and the Koi pattern makes each individual fish uniquely patterned and visually striking. An excellent choice for a planted community tank or a Betta sorority setup.
