Vieja

Vieja is a genus of cichlid fish from Central America and Mexico. The majority of the species are freshwater fish found in stagnant or slow-moving waters of southern Mexico to El Salvador, but V. maculicauda, which also occurs in brackish waters, ranges south to Panama. They are high-bodied cichlids that reach lengths of up to 17–35 cm (7–14 in) depending on the exact species. Vieja feed mostly on vegetable matter, but may also take small invertebrates.
