Psalidodon fasciatus, commonly known as the banded astyanax, is a species of freshwater ray-finned fish belonging to the family Acestrorhamphidae, the American characins. This fish is widespread in the Americas from Mexico to Argentina.[3] It grows up to 17.1 cm (6.7 in) in length.[4] Formerly thought to be closely related to the Mexican tetra, it is now in the same genus as the Buenos Aires tetra.[5]

It is the target species of the scale-eating Deuterodon heterostomus which is a close mimic.[6]
