Competition between Color Morphs of the Polychromatic Midas Cichlid Cichlasoma citrinellum.

The Midas cichlid, Cichlasoma citrinellum, is a polychromatic fish that occurs in Nicaragua. All of these fish start life as normally colored, cryptic individuals. In some populations a few fish change into conspicuously colored morphs, most frequently gold.
