Etymology: Amphilophus: Greek, amphi = on both sides + Greek, lophos = crest (Ref. 45335); tolteca: The name relates to a pre-Columbian culture in Central America that was probably responsible for a mural painting of a feathered serpent, called Quetzalcoatl, close beside Lake Asososca Managua. According to a folk tale, the deist pictogram guards the lake.
