Blackfin Goodea is an endemic to Mexico. It occurs in nine Mexican federal states over the central part of the country, and has been introduced to two more states.
Blackfin Goodea has the largest distribution range of all Goodeid species. Still, it is estimated that the species is already disappeared from ca. 20% of its historical range.
The numbers are currently decreasing. Water pollution, groundwater pumping, droughts and invasive fish species are the major threats to the species.
