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]
The fish was named in honor of C. Basil Jordan of the Texas Aquaria Fish Company (Dallas, Texas, USA), who donated the type specimens and for making his discovery of the first recorded blind characin known to the scientific and aquarium world.[11]
It reportedly has been introduced to the Philippines.[3]

Astyanax jordani es una especie de peces de la familia Characidae en el orden de los Characiformes.[ru] Astyanax jordani
Astyanax jordani (лат.) — вид лучепёрых рыб, обитающих в мексиканских[1] пещерах. Не следует путать его со слепой пещерной формой другого вида — Astyanax mexicanus. При этом виды родственны и есть мнение, что Astyanax jordani всё же младший синоним или подвид Astyanax mexicanus.Другой контент может иметь иную лицензию.
