Also called the Redhead or Firehead Cichlid, the Quetzal Cichlid is endemic to the Rio Usumacinta basin in western Mexico and Guatemala as well as parts of Belize. These fish tend to inhabit slow-flowing lowland waters such as rivers and lakes, but is sometimes found in brackish environments. This species is one of the most colorful cichlids, exhibiting a metallic green, blue, red and orange coloration along the flanks. Many specimens also have dark spots or splotches near the caudal fin and along the belly.
