Vieja is a genus of cichlid fish from the Pacific slope of 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.[1] They are high-bodied cichlids that reach lengths of up to 17–35 cm (6.7–13.8 in) depending on the exact species.[2] Historically, Vieja was included in Cichlasoma. Once recognized as its own genus, it first included most of the superficially similar, relatively large and high-bodied cichlids of Central America and southern Mexico, but several of these are now considered to belong to separate genera: Chuco, Cincelichthys, Isthmoheros, Kihnichthys, Maskaheros and Oscura.[1][3] Vieja feed mostly on vegetable matter, but may also take small invertebrates.[2]
