Species Profiles
German Blue Ram
Mikrogeophagus ramirezi
German blue rams are one of the most beautiful dwarf cichlids, with iridescent blue and gold coloration, a distinctive black spot, and red-highlighted fins. Despite being cichlids, they are remarkably peaceful and make excellent centerpiece fish for planted community tanks. They do require warm, soft water and are more sensitive than typical community fish.
