This is a good question, because Africa is a giant continent with over a thousand species of cichlids.
Some are loners, some not, some like to live in species groups, some can live in communities.
Some love hard water, some soft, some neutral or it won't matter.
If you were to narrow it down to rift lake African Mbuna species of lake Malawi you may get a few answers, if you asked about Aulonacara from Lake Malawi it may be different, or if you said said Tropheus of Lake Tanganyika, the answers may be totally different.
If you narrow it down a bit, the OP question can be more reliably answered.
An example
If you want some Kribensis type, and some rift lake type Mbuna, it might require 2 different tanks.
