Astyanax jordani is a freshwater fish of the characin family (family Characidae) of order Characiformes, native to Mexico.[3][4] It is sometimes called the cave tetra, or by its local Spanish name tetra ciego.
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,[5][6][7][8][9] but others continue to recognize the two as separate species.[10]
A. jordani is listed on the IUCN Red List as Vulnerable on the basis of shrinking population and an acutely restricted and diminishing habitat.[1] It is fairly resilient, however, having a population doubling time of 15 months.[3]
It reportedly has been introduced to the Philippines.[3]
