Astyanax jordani is a freshwater fish of the characin family (family Characidae) of order Characiformes, native to Mexico. It is sometimes called the cave tetra, or by its local Spanish name sardina ciega.
A blind cave fish, A. jordani is very closely related to the Mexican tetra (A. mexicanus) and their taxonomy is disputed. Some treat the two as variants of a single species (in which case A. jordani is a junior synonym of A. mexicanus) and this is supported by phylogenetic evidence, but others continue to recognize the two as separate species.
A. jordani is listed on the IUCN Red List as Vulnerable on the basis of shrinking population and an acutely restricted and diminishing habitat. It is fairly resilient, however, having a population doubling time of 15 months.
It reportedly has been introduced to the Philippines.
