Competition Between Color Morphs of the Midas Cichlid, Cichlasoma citrinellum, in Lake Jiloá, Nicaragua

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. When kept in unmixed color groups, golds and normals grow at the same rate; but when they are mixed, growth of the golds becomes faster an...

Physiological responses to salinity increase in blood parrotfish (Cichlasoma synspilum ♀ × Cichlasoma citrinellum ♂)
