Description
The Mexican Tetra is a hardy and adaptable characin species, known for its silvery body and a distinct dark spot on its shoulder. While famous for its blind, cave-dwelling morph, the sighted form is an active and generally peaceful community fish. They are schooling fish that thrive in a well-maintained aquarium with ample swimming space.
