Mexican Identity
The retrieved species account identifies a Mexican distribution under Astyanax mexicanus. Taxonomic revisions have separated related North and Central American tetras. Older broad locality records should therefore retain their original names rather than being assigned automatically to this species.
Freshwater Habitat
Fish occur over rock and sand in pools and backwaters of streams and rivers and also in springs. These varied waterbodies share sheltered areas. A spring record and a river-backwater record should keep their distinct environmental context rather than being merged into one uniform setting.
Feeding and Size
Insects, crustaceans and worms are recorded foods, and eggs may be placed in crevices. The compiled maximum is twelve centimeters total length. A distinctive cave or surface population requires its own documented identity before special traits are generalized to every Mexican Tetra.
Keep the Population Identity
Cave and surface records can differ in important traits. Preserve locality and taxonomic evidence before generalizing an unusual appearance or behavior.
