Zoogoneticus tequila, Tequila splitfin or simply Tequila fish, is a species of goodeid fish (family Goodeidae) from Mexico.[3][4][5] The specific epithet, tequila, derives from the Tequila Volcano, which looms near the type locality.[2]
Distribution and conservation
Zoogoneticus tequila is endemic to Mexico. Its current distribution is restricted to a single spring pool in Teuchitlán, only 4 metres (13 ft) in diameter, where a population consisting of less than 50 adult fish live.[6] Even in this habitat, it is outnumbered by introduced guppies by a factor of six.[7] Before the discovery of the pool population in 2000/2001, Zoogoneticus tequila was generally thought to inhabit rivers; however, no fish could be found in the original habitat and the species was considered extinct in the wild.[1] Introduced fish species have been implicated in the disappearance of Zoogoneticus tequila from its type locality.[1][6] Habitat deterioration may also have contributed. Pollution and water extraction are threats to the pool where the wild population persists. Captive populations are maintained by aquarists.[1]
Description
Along with other Mexican goodeids, Zoogoneticus tequila are viviparous; this lead the genus to be originally included in family Poeciliidae.[2] Clutch size is up to 29 young.[1] Males are smaller than females, with standard length up to 41 mm in males and up to 58 mm in females.[2] Total length can reach 70 mm in females.[3] The sexes can also be distinguished by colouration.[2]
