I'm looking to purchase a new tank, but I'm really bouncing around. If I were to construct a 55-gallon mbuna cichlid tank, should I be purchasing one of each cichlid, or should I go more for 1 male to multiple females per species? I am aware of the hardscape requirements but not as much for fish to fill the tank. So, what I'm mostly looking to find out here is whether it's best to purchase one of each type of fish, for example yellow labs, acei, afra (if I can find it lol), or should I go for the whole 1 male to 5-ish females thing and just have a few different species? My main concern is that the fish will not get along and will be aggressive due to just not being compatible, or from too many males and not enough females, etc. I've done some research, but I really can't figure out whether it'd be a problem to have one of each species of mbuna cichlid or not.
