Hey sorry your inbox was full and I didnt want to re-write it.... so here's my reply! 
Btw your link didnt work, but thats ok.
I would suggest doing some africans, malawi cichlids, especially if you want color. A group of P. saulosi would be perfect, that would give you yellow females and blue males, and they look great. I would do one male with at least 3 or 4 females.... then you could probebly add one or two more species such as socolofi or rusty cichlids... make sure they are smaller species and 'less aggressive' mbuna. I would stay away from yellow labs with saulosi because of the similar color you *may* get males bugging the female labs to breed, but if you have enough saulosi females then you should be okay. If you really wanted, you could probebly get both yellow labs and saulosi. I would not do more than 10 fish.... as when they reach full size it would be cramped. Aim for 6-8 fish.
Africans are aggressive no matter what, so they are always going to be chasing... its in thier nature and its part of what makes them so entertaining.
Have sand substrate, lots of stable rockwork, and a good powerful filter cus these guys are messy. Adding crushed coral into the substrate or into a stocking in the filter will help raise the pH up to what it needs to be (approx. 8.0).
Have you ever tried Kribensis cichlids before? They are easy to breed and fun to keep. Although a 20 gallon "tall" tank will be pushing it for territory space... however I kept a pair successfully in a 10 and 20 gallon, you just need to have lots of hiding places. Blue rams are nice too... as well as apistogramma.
If you have any other questions ask away!
