Skiffia is a genus of goodeid fish that contains four species, endemic to the Mesa Central area of west-central Mexico.

They inhabit stagnant or slow-moving waters such as lakes, ponds, channels and ditches, and prefer shallow depths.

[5] All four Skiffia species face some conservation threat and have suffered local extinctions in more than 50% of areas studied where they were previously known to have existed.

[5] S. lermae and S. bilineata are the most widely distributed of the genus, found over the states of Michoacán, Jalisco and Guanajuato.

Captive populations of S. francesae are maintained in a variety of locations by aquarium hobbyists, research institutes and zoos.
