i have done that, started a trial tank & am now completely hooked on africans. I am in the process of getting together all the equipment for my new 4 footer. I currently have 5 fryeri, 3 e yellows, 2 red zebras & 2 cobalt zebras. they are all about two inches long & they are in a two footer 24Lx20Hx12D. they have enough room for now. the only setup difference between my african & community tank is crushed marble as a substrate to raise the ph a bit. my ph is around 7.8 & they do well. I do recommend a high filtration rate, I have a cf1000 on my +-100L african tank.
