They are endemic to the Teuchitlan Springs in the upper Ameca river basin in Mexico, where they inhabit small lakes, tributaries and freshwater springs.<\/p>\n<p>First discovered in 1955 in a small lake, overlooked by the Tequila Volcano. A volcano which gives the species its name. However, it was not until 1998 that they were officially classified as their own species. Their original habitat was a small lake with a diameter of just 8 metres and a depth of 1.3 metres.<\/p>\n<p>Considered extinct in the wild after a series of unsuccessful searches in 1998. However, just three years later, a small population containing a handful of adults was found. Similarly, this was in a small lake that measured between 3 and 4 metres in diameter. Distressingly, as of 2013, these are also extinct.<br \/>In 2015 a reintroduction programme began, driven by captive breeding projects around the world. The IUCN (International Union for Conservation of Nature) estimated this population to have around <a href=\"https:\/\/www.iucnredlist.org\/species\/169395\/1276460\">80 adults in 2018<\/a>. Thankfully, numbers are growing at a steady rate. This new population inhabits an oxygen-rich freshwater spring which is 4 metres in diameter and an average depth of just twenty centimetres.<\/p>\n<h3 class=\"wp-block-heading\">Tequila Splitfin Conservation<\/h3>\n<p>The survival of the Tequila splitfin now faces a multitude of threats in the wild.

However here at <a href=\"https:\/\/neuronicdev.es\/bpa\/\" target=\"_blank\" rel=\"noreferrer noopener\">Blue Planet Aquarium<\/a>, we believe that every species is entitled to a fair shot at survival, especially when it\u2019s decline is largely caused by human activity.<br \/>Here at Blue Planet Aquarium, however, we now have a healthy group of Tequila splitfins. Thanks to Bolton Museum Aquarium, we were able to become part of a nationwide captive breeding programme. As a result, this will allow Blue Planet Aquarium to contribute new offspring to other collections that will work towards ensuring the future of this characterful species. Hopefully, in time, the waters of the Ameca river will teem with Tequila splitfins once again.<br \/><em>Author: Dan Goodyer, Aquarist at Blue Planet Aquarium&nbsp;<\/em><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Tequila splitfin (Zoogoneticus tequila), is a small freshwater fish measuring up to 8cm long \u2013 with females being slightly larger than males.
