good job.
I'd probably get a ton more rockwork in there for them; the mbuna in particular will appreciate it, as will your lone frontosa at his current size (he's going to be very jittery in there on his own with all the fast movers).
Think about some real plants if you like the look of plants in an African tank - personally I do - (Java Ferns, Java Moss); great for keeping nitrates down, and I assure you from personal experience it can be done very easily.
you probably would ideally increase your mbuna groups to hit 1 male, 2 or 3 females in each. same gender breakdown for the ahli, same for the victorian haps. Not sure about how much room that leaves you though.
I see you have 2 jacobfreiberg; both male ? probably ok anyway in a tank that size, just if there was only one female again she may be overly stressed by the male.
