I just bought a butti at 3" for my african 40 g. high. I honestly have never seen one around here anywhere. I hear they get pretty crazy, but I had no idea what pretty cichlids they were until i got one. So far in my 40, I have a red zebra who owns the tank at 4", he's pretty active, and he was free, a yellow lab also at 4" who's very chill, a blue zebra at 2.5", that kinda resembles a rusty top cichlid, purple striped body with fading to gold fins, the very shy, but pretty active butti, and,I also added a 3.5" tinfoil barb, who basically just follows the yellow lab around. Is this too many fish for this sized tank or can I add a few more? I would like to know because, I wanted to do something a little different with this tank. I know its only a 40 g., I just thought I'd give africans a shot, but I dont want to overcrowd either. - thanx, salty
