Gila Chub (Gila intermedia) is a small (6 cm), secretive fish that was historically distributed through the Gila River basin in Arizona and New Mexico, but currently occurs in southeastern Arizona and in remnant populations in two creeks (Mule Creek and Turkey Creek) in southwestern New Mexico. They are typically found in the quiet, deep waters of pools or hidden by the cover of vegetation, boulders, and fallen logs. They are known to eat insects, algae, and fish. Recent taxonomic work suggests that Gila Chub in New Mexico may be the same species as two other limited-distribution fishes of the Lower Colorado River drainage, Headwater Chub (Gila nigra) and Roundtail Chub (Gila robusta).
