I've been researching cichlids (like a maniac) because I'm almost ready to put fish in my 55 Gal tank. I plan to have a mbuna tank but have, for some strange reason, fallen in love with the pics of Blue Moorii. I've read that they can co-exist with "peaceful" mbuna. Can someone suggest some tank mates for them? This is my first fish tank, so please include numbers I should get and male/female ratios. Thanks!
