The Monterrey Platyfish (Xiphophorus couchianus) is a freshwater fish of the family Poeciliidae that grows up to 4 cm.
Description
The Monterrey platyfish is a small livebearing fish endemic to fresh water around Monterrey in northeastern Mexico. The species reaches only about 4 cm and has a stocky, olive-grey body without a bright colour pattern. Like other platies the female gives birth to live young and the male carries an anal fin modified into a mating organ. Owing to the drying and destruction of its springs the species has all but vanished in the wild. The IUCN assesses it as Critically Endangered (CR).
