Description

The Gila topminnow is a livebearing molly (Poeciliidae) from fresh and brackish water of the Gila River system on the border of Mexico and Arizona. The species grows to about 6 cm. Through introduced mosquitofish and habitat loss the species is vulnerable. As a surface fish it lives in streams, pools and springs and eats algae, small invertebrates and detritus. The female gives birth to live young. Due to its very restricted range the species is vulnerable. The fish is harmless to humans.
