Although extremely colorful and widely available, M. auratus is not a good choice for the novice at keeping Malawi cichlids. Males are extremely aggressive and the dominant one will try to kill any other males of its species, as well as females if they are not in spawning condition or are not provided with adequate hiding places. Only one male should be kept per aquarium, and at least three or, preferably, four or five females provided.
To be kept successfully, at least a 55 gallon aquarium well provided with rocks or other cover is advisable
Quote from a cichlid forum article on the fish. Do some research JRD!
