Astyanax belizianus is a small freshwater fish native to various regions of Central America. Little is known of its diet or specific environmental preferences, but it was first recorded in Belize. Modern ichthyology has expanded its range into Guatemala and Honduras, where it inhabits various rivers and lake tributaries. It is a silvery fish that may have a slight yellowish tint to its scales. The body is deep, especially in comparison to similar species from the same genus.

Its original description nominated it as a member of genus Tetragonopterus, which is not uncommon for members of Astyanax named in the late 1800s. A. belizianus was considered synonymous with congener Astyanax aeneus for a great deal of its existence, but recent research into the phylogeny of the genus (2017) has resurrected it from synonymy and re-granted it species status.
