I have a mbuna tank going, I only got 9 of them to start out with, I was planning on looking into it more and figuring out just what I wanted...well now I have and I was wondering what the best way was to introduce more fish into this tank, as these are some pretty aggressive little buggers! I tried to put a small pleco into the tank and they were on him like white on rice in half a second, so how can I get more fish in there without them getting picked on too badly? I'm wanting to add an acei, a red zebra, and an ob zebra for right now....
