I've done a lot of reading about starting my own african cichlid tank for my 55G, but I decided I didn't want to because of the cost. To my understanding, the best type would be the Mbuna of Lake Malawi. Overstocking the tank is a must, because it will divide the aggression out, then follow it with over-filtration. General set up would be 3 species of Mbuna, 1 male and 3-5 females of each. If you chose to go with Demasoni as one of the species, go for 2 males and 8-10 females, smaller size, and a bit less aggressive, so higher numbers will help them stand against the other species. My plan was Demasoni (Blue, black barred) 2M 8F, Psuedotropheus Acei 1M 3F and Red Zebra 1M 5F. I found almost all of the info I needed here:
