Astyanax is a genus of freshwater fish in the characin family (family Characidae) of order Characiformes. The type species is A. mexicanus, the Mexican tetra. These fish are among those known as tetras.[1] [2] With roughly 100 Astyanax species, this genus is the most species rich genus ot the entire order, but this requires much work. [3]
The blind cave fish, a form of A. mexicanus, is a famous member of this genus. A. jordani, a different but closely related blind fish, was formerly considered to form its own genus, Anoptichthys.
The generic name comes from Astyanax, a character in Greek mythology who was involved in the Trojan War.
