Description
The Mexican Tetra is a highly adaptable and hardy freshwater fish, known for its silvery body and active schooling behavior. This species is famous for having both a sighted surface-dwelling form (as pictured) and a blind, cave-dwelling form. They are generally peaceful but thrive best in groups of six or more.
