U would be amazed at how well africans color up if u put them in a higher ph such as 8.0 and in a species only tank containing just a male and a few females. Petshops usually keep their fish around neutral cause its easier fir them to maintain all different tanks.
When i brought home my deepwater haps they looked good in store but once home and adjusted they the male atleast doubled in intensity. Also there is always a dominant male in a tank so if u have a community of africans in a tank all the other males will probably never show their full potential.
