I guess i put this is the wrong place the first time. I was recently at my lfs, I was some keyhold "fish" I have a tropical community tank. I wasn't aware that they keyhole was a cichlid. I was shocked when i found out. But after reading further I found out that they were peaceful and could be kept in a tropical tank. So my question is--do I need more than one. Right now my little kenny is the only one that i have. Should i get more and if so how many??
