The La Palma Pupfish was endemic to only one spring-fed pool of some 10 sq. metres in a Mexican desert.
Discovered only in the early 1990s, it is now extinct in the wild (since 1996) following human drainage of the pool for irrigation
but a small population survives in captivity.
The breeding male has beautiful milky white irridescent scales and a thick black border to the tail. They grow to 5-6cm long.
Female.
Breeding male.
The Charco Palma Pupfish, also called the Charco Pupfish, is also now extinct in the wild following human drainage
of its habitat but a small population survives in captivity. It is superficially similar to the La Palma and Potosi pupfish.
