Appearance

A blind cave fish, "A. jordani" is very closely related to the Mexican tetra and their taxonomy is disputed. Some treat the two as variants of a single species and this is supported by phylogenetic evidence, but others continue to recognize the two as separate species.

Naming

The fish was named in honor of C. Basil Jordan of the Texas Aquaria Fish Company, who donated the type specimens and for making his discovery of the first recorded blind characin known to the scientific and aquarium world.

Status

"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.
