Mikrogeophagus ramirezi, commonly known as the Ram Cichlid or Dwarf Cichlid, is a small, vibrantly colored freshwater fish belonging to the family Cichlidae. It is highly prized in the aquarium hobby for its striking appearance, peaceful demeanor (for a cichlid), and interesting breeding behaviors. These fish exhibit a complex social structure, particularly during breeding, and are known for their intelligence and responsiveness to their environment.

Colorazione

Wild-type M. ramirezi exhibit a striking array of colors. The body is typically golden-yellow to iridescent blue, often with a prominent black spot on the flank, sometimes encircled by iridescent blue. A black stripe runs vertically through the eye. The fins are often edged in red or orange, with iridescent blue spots on the dorsal, anal, and caudal fins. Males are generally more colorful and have elongated dorsal and anal fin rays, with the second or third dorsal ray often extended into a filament. Females are typically smaller, less intensely colored, and have a reddish-pink belly, especially when breeding. Numerous captive-bred color morphs exist, including 'German Blue', 'Electric Blue', 'Gold', and 'Balloon' varieties, which can vary significantly from the wild coloration.
