Zoogoneticus tequila

Zoogoneticus tequila, the Tequila Splitfin, made international conservation headlines when it was declared extinct in the wild in the early 2000s. Thanks to an extraordinary collaborative effort between the Chester Zoo, the University of Morelia, and dedicated hobbyists, a captive population was maintained and individuals were successfully reintroduced to the Río Teuchitlán in Jalisco, Mexico.

Males display an attractive spotted body pattern with subtle orange or yellow tones on the fins. This species holds particular significance in the conservation world as a symbol of what dedicated hobbyist involvement can achieve for endangered fish.

Keeping Tequila Splitfin in the hobby contributes to the genetic diversity of the captive population and raises awareness of the goodeid conservation crisis.
