Thorichthys is a genus of cichlid fish that is native to the Atlantic slope of Middle America, ranging from southern Veracruz and the Yucatán Peninsula in Mexico, to Guatemala and Honduras, with introduced populations in a few other countries.[1][2] They tend to inhabit moderately-flowing to standing water such as rivers, streams, lakes, ditches and lagoons, and they are primarily freshwater fish, although T. helleri and T. meeki may occur in slightly brackish habitats.[2][3]

Thorichthys have somewhat pointy heads and stripes down their body, and mostly feed on invertebrates and detritus. Members of Thorichthys do not exceed 17 cm (6.7 in) in standard length,[4] and they are popular aquarium fish, especially the well-known firemouth cichlid (T. meeki).[2] Genetic evidence shows that Thorichthys is most closely related to Salvin's cichlid, the only species of the genus Trichromis, which is morphologically and behaviorally rather different. In contrast, Thorichthys is not particularly close to Cribroheros despite having several features that are similar.[5]

Thorichthys es un género de peces de agua dulce perteneciente a la familia de los cíclidos. Las nueve especies que se reconocen en este género se distribuyen en América Central. Todas ellas presentan una cabeza bastante aguda y rayas horizontales en el cuerpo y tienen a habitar en aguas tranquilas. Los miembros de este género raramente superan los 13 cm de longitud, lo que los convierte en populares peces de acuario. La especie más popularmente conocida del género es el denominado "cíclido boca de fuego" (Thorichthys meeki). El género fue inicialmente descrito en 1904, pero sus especies fueron transferidas a un subgénero de Cichlasoma en 1907. En 1996 fue restablecido como un género independiente.Другой контент может иметь иную лицензию.
