I know theres some people on MFK who keep emperors...they're awesome but like cant009 said, they get huge. You would need a pool lol Thats a good show too
I've kept them several times and they are among my favorite cichlids. Awesome personalities and great non-picky eaters. The problem I've always run into is that after 6months or so they are 16-17" and start to get aggressive towards tank mates. I'll most likely try them again at some point.
