Everything I have read on African Cichlids (and right now I am in the process fo researching before setting up a tank, so its been quite a bit), has said that in general, African Cichlids are agressive fish and not meant to be in a standard community tank.
Something else to consider: African Cichlids thrive in a high pH, high KH water. Angels tend to prefer soft water and a lower pH. These fish have two very different needs. What is your water's pH? Everything I have read so far says that the MINIMUM pH is 7.5, or else you will need to raise it with baking soda.
What size of tank are you considerign putting this fish in? What other tankmates are there?
