Welcome to Cichlid-forum!
Don't look at pictures for advice, it might have looked like that for one moment or one day. You want something that will work throughout a two year period or longer.
What are the dimensions of your tank? What is your stock list including size and gender and count of each.
I would say the recommendation will be to adjust your stock. With mbuna, even if the tank is filled to the waterline with rocks you should see plenty of the fish at all times.
