Swordtails are sleek, powerful swimmers named after the long, sword-like extension on the bottom of the male's tail fin. They bring amazing energy and a dramatic silhouette to medium-to-large setups. The most sought-after commercial variants in Australia are the Kohaku / Koi Swordtail (a translucent white body with vivid orange patches, mimicking pond koi), the Green Swordtail (reflecting iridescent wild-type greens and reds along the lateral line), and the Neon Swordtail (sporting an ultra-bright, metallic red and blue reflective body).
