Astyanax caballeroi is a small species of freshwater fish endemic to a single lake system in Mexico. It has a longer snout and more slender body than most other species in the genus Astyanax, thought to be the result of predatory behavior; while A. caballeroi eats invertebrates and smaller fish, other Astyanax species are more broadly omnivorous, and have deeper bodies with shorter snouts. This difference in body shape once placed A. caballeroi, along with several other species of Astyanax, into the former genus Bramocharax.
Its coloration - a combination of green and silver with black details - is not at all uncommon in species of Astyanax native to Mexico. Its other physical differences, however, allow for easy delineation between related species. For instance, congener Astyanax aeneus is one of the closest relatives of A. caballeroi, despite the disparity in appearance.
