Poecilia mexicana, Campeche, a wild shortfin molly, is a North American livebearer related to and in the same genus, Poecilia, as the guppy and other mollies. This species is native to Mexico. We acquired this fish in June 2009 from Dr. Ptacek of Clemson University. They were earlier collected from the wild by Dr. Ptacek. We intend to maintain it as a species and also to use it to create new strains via hybridization with other Poecilia and with our commercial mollies. Males reach about 2.5 inches (6.35 cm). Females are somewhat larger and much heavier. This fish lives to be about three years of age. Male P. mexicana, Campeche mollies have blue gray bodies. The caudal (tail) has an orange and black border. Females have gray-green bodies.
