German Blue Ram

Mikrogeophagus ramirezi (ram cichlid) is a dwarf cichlid found in the Orinoco river basin in the savannahs of Venezuela and Columbia in South America. Male specimens of the ram usually have the first few rays of the dorsal fin extended, but breeding has made some females also show this. The water is generally slow-flowing, contains few dissolved minerals, and ranges in colour from clear to darkly stained with tannins.
