First off I do admire your desire to take the advice offered here. I will admit that I hate when people post here and don't at least think about the answers they get or just take the advice they want to here. So for that I hope you get the help you are looking for.
However I must say you need to give us a little more. You need to do some of the work your self and research a little on what you are looking for. Then after that work out a few choices and ask us our opinions and go from there. It is hard to just tell people what fish to keep without at least first having them narrow it down a little. Give us a list of a few that you are interested in and are available to you. I would hate to recommend a cichlid you have never heard of or can't find in your area.
Lastly to clarify something are you for sure saying you are keeping the two BP's in this tank? Cause if so I would say that would greatly limit your stock list to almost nothing else. If you want to go with breeding cichlids for the first time, at the risk of being sounding cliche, I would do convicts. They are extremely easy to get a hold of, cheap, and breed like crazy. Plus they are fun with great personality. Otherwise there is always HRP's, sajica, firemouths, and rainbows.
Good luck and I hope this helps.
