Astyanax abramis is a small freshwater fish from the inland rivers of South America. It is plentiful in almost the entire continent, with a habitat including the La Plata, upper Amazon, and Meta River basins. The body shape is subrhomboidal (somewhat rhomboidal) and laterally compressed, and the scales are largely silver, with a blue or green tint on the dorsal side.
As a cryptic species, A. abramis could possibly constitute multiple species that are currently undescribed. A. abramis is also a part of a species complex that includes itself and various congeners, including Astyanax bimaculatus, the namesake of the complex, and Astyanax lacustris, which is very closely related to A. abramis and looks very similar. Astyanax is a particularly speciose genus wherein cryptics and complexes are not uncommon.
