Like all Melanochromis species the M. johannii has horizontally striped males and females of different colors. Males are a variable bluish black with pale blue or royal blue stripes. The dramatically different females are orange or yellow-orange with indistinct blackish stripes. M. johannii is currently one of the more widely available mbuna species. Unfortunately, like most members of the genus Melanochromis, this one has aggressive, territorial males which require a large aquarium with plenty of rockwork or other hiding places. If not provided with such quarters, the dominant male may pursue and kill any subdominant males and perhaps females that are not ready to spawn.
