Xiphophorus Genetic Stock Center

Dedicated research resource for the Poeciliid fish genus Xiphophorus

Faculty and Staff

The Xiphophorus Genetic Stock Center currently houses 24 of 26 species of the freshwater genus Xiphophorus. In their natural environment, these fishes live in drainages in eastern Mexico, Guatemala, Belize and Honduras, with most of the described species living in Mexico. The taxa make up three groups: the Northern Swordtails, the Southern Swordtails, and the Platyfish.

The purpose of this site is to provide information to both the research community and the general public about the Xiphophorus Genetic Stock Center. As a national resource for research animals, we welcome opportunities to share fish with the research community for further research, development, and application.
