The Blue Ram, Mikrogeophagus ramirezi, is one of the best know and most popular of all cichlids. It has a host of common names including; the Butterfly Cichlid, the Ram Cichlid, Blue Ram, German Blue Ram and Gold Ram. Although they are rarely referred to as Butterfly Cichlids any more, most of the other names are commonly used. The Gold Ram is a true-breeding color strain that has been in the hobby for many years. Although they are very different in color they are exactly the same fish and easily cross breed with Blue Rams. In 2009 a new color form was introduced to the hobby and the "Electric Blue Ram" is now found in many pet stores.
