Astyanax argentatus is a small freshwater fish native to northern Central America and southern North America. Given its native range, it is also known as the Texan tetra. Little has been published regarding the feeding habits or behavior of A. argentatus, but it is known to have the northernmost distribution of any member of the genus Astyanax.
There is debate regarding its status as a species, as it was considered a synonym of the Mexican tetra (A. mexicanus) for 20 years, but it has recently come back into favor as its own distinct entity. Various morphological specifics indicate their separation, though some resources still consider them synonymous. It also has visual similarities to various other members of the genus; its silver scales, single humeral spot, and yellowish or reddish fins are not uncommon features therein.
