Taxonomy Until 2019, ''Pristella'' was a monotypic genus, but ''P. ariporo'' was described in 2019. Additionally, ''Hyphessobrycon axelrodi'' may belong in ''Pristella'' due to its conical teeth, but further genetic studies are needed to confirm this.

Unlike most other characins, it is tolerant of (and sometimes found in) slightly brackish water. It is small (up to around in length) and lives in large groups, and males can be distinguished from females by being smaller and thinner than the females. Like most other tetras, it feeds primarily on small insects and planktonic animals. Nomenclature Older aquarium books often refer to this species by the junior synonym ''Pristella riddlei''. Aquarists tend to refer to this fish as the golden pristella tetra, though some call it the X-ray tetra, instead.
