Africans (specifically Malawi) Cichlids are some of the most colorful freshwater fish. And as they are aggressive, they are very active in the tank. Hence, African form excellent "Show tanks" for living rooms to entertain guests who more often than not will have no idea about fish. As mentioned by others, African cichlids are not as "interactive" as CA/SA ones.
CA/SA tanks can usually be appreciated only by people who know that a GT is not the same as a FH. I very nearly stabbed this cousin of mine who looked at my Jaguar and suggested I should get him FH food so that he gets a "kok" and looks better.
If you don't want to stab your relatives, please go for a colorful Malawi (Hap) set-up with lots of Yellow Labs and Blue Dolphins... If you do go for a CA/SA set-up, keep it away from wannabe "critics".
Just my 2 cents,
