Tequila Splitfin

Tequila Splitfin is a tiny fish found only in Rio Teuchitlan, Mexico, in a small spring pool. Scientists assumed the Tequila Splitfin had become extinct since no specimens have been found since 1992. The only known remnant colony of Tequila Splitfins, however, was discovered in 2005. It is thought that there are only around 500 Tequila Splitfins left in the wild, with about 50 mature fish.

Fortunately, conservation measures are presently underway to help replenish the natural population of Tequila Splitfins. The Mexican Fish Ark, which is situated at the University of Michoacana of San Nicolás de Hidalgo, has been rearing various endangered goodeid species, including the Tequila Splitfin. Conservationists released 700 Tequila Splitfins back into the wild in 2017, hoping that the species will recover.
