Yellow labs and acei, are great mbuna to start with because they are really mellow (i kept mature yellow labs with angels with no problems... wouldnt reccomend it though unless your willing to risk the angels. fish in general can be unpreditable)
Bumblebee cichlids are the LAST fish i would reccomend, they are incredibly unpredictable. my male would be fine one day and kill three the next for absolutely no reason. i finally decided to get rid of him when he ripped the eyes out of a catfish, who survived btw and is still doing well.
Auratus are for either professionals, species tanks, or hyper-aggressive tanks. a young male i "adopted" from a teacher killed a strongly established red zebra more than twice his size. pure blooded crazies
frontosa are for experienced keepers only, who know what fish they can be kept with safely. they need to be kept in fairly large groups (at least 6) and need a very large tank, not to mention they easily reach 10 inches and often larger.
personally, i would reccomend peacocks (smaller varieties), yellow labs, demasoni, maybe red zebras, and a synodontis catfish (something like an upside-down cat or a featherfin synodontis... only one, since most compatable catfish are co-specific aggressive and get to be about 5 inches or larger)
good luck!
