The Blushing Swordtail is a North American livebearer related to and in the same genus, Xiphophorus, as the platies. Most commercial strains of swordtails have mixed heritage, including ancestors from X. helleri, X. maculatus and X. variatus. Commercial swordtails are primarily descended from X. helleri. Males often reach 7.5cm (3 in.), not counting the swordtail. Females are somewhat larger and much heavier. Both sexes have gray-green bodies and red fins. Males like all swordtails have an extended “sword” from the bottom margin of caudal. Males often have one thin orange and blue lateral stripes flanking the lateral line. This fish has no natural range, but of its ancestors hail from Mexican and Central America.
