The White Mickey Mouse Maculatus is a North American livebearer related to and in the same genus, Xiphophorus, as the swordtails. Most commercial strains of platies have mixed heritage, including ancestors from X. helleri, X. maculatus and X. variatus. This fish is largely descended from X. maculatus. The top photograph is of a mature male. The bottom picture is a mature female showing off her gravid spot. Males often reach 4cm (1.5 in.). Females are somewhat larger and much heavier. Both sexes have pinkish-white bodies and often a splash of red at the base of the dorsal. Additionally, both sexes sport the “mickey mouse” pattern of a large black spot in the caudal peduncle (the head of the mouse) and two smaller spots, one each at top and bottom of the base of the caudal fin (the ears). This fish has no natural range, but its ancestors hail from Mexican and Central America.
