Well there are two things you need to know about how many africans you can keep.
1) The gallons of a tank don't matter as much as the footprint(LxW)
2) There is no rule about how many inches per gallon or anything like that.
Also, how many you can keep will vary wildly with which species you select.
I would suggest you certainly get rid of the kenyi, and get a few more acei as a starting point. Then if you had a 55, you could do 2 more species with approximately 5 or 6 fish of each. I would ask this same question in the malawi folder though as you are likely to get more responses. Good luck
