General: The German Blue Ram (Mikrogeophagus ramirezi) is a colorful, South American Dwarf Cichlid. The German Blue Ram will reach a length of three inches, and live up to five years in captivity. As an individual, the German Blue Ram may only require an aquarium of twenty gallons. As a pair, the German Blue Ram should be kept in twenty-nine gallons, or more. The mated pair will become defensive, as they exhibit parental behavioral strategies.

Fecundity: The German Blue Ram (Mikrogeophagus ramirezi) may produce up to 250 eggs per clutch. In order to encourage reproductive behaviors, it is best to mimic the natural environment of that particular species. An acidic pH, soft water hardness, caves made of porous rock, and a well-balanced omnivorous diet will promote the production of viable offspring.

Preferred Water Chemistry: Acidic (5-7 pH), soft water (3 to 6 dGH)

Aquarium Diet: Brine Shrimp, Baby Brine Shrimp, Blackworms, Omnivore Pellet, Spirulina

Dimorphism: The German Blue Ram (Mikrogeophagus ramirezi) male will develop elongated dorsal, pelvic, and anal fins. The female will retain her short, round fins. The male will also produce a brighter coloration, once mature. The female will develop a purple patch towards the posterior (back) half of the operculum (gill cover).

Compatibility: The German Blue Ram (Mikrogeophagus ramirezi) are typically compatible with Danio, Tetra, Rasbora, Pencilfish, Hatchetfish, and Corydoras.
