I would look to increasing the number of caeruleus and acei. You could also look at adding another crabro or two. Your Peacocks might get hammered. Your red zebra(Metriaclima estherae) might change colour depending on whether or not it is male or female. Males are blue with the females being an orange/red colour. Wait till the fish is about 2+ inches and then you should be able to sex it. Venting being the best method.
You could look at some of the Cynotilapia species for some coloue variation or possibly the Pseudotropheus sp"elongatus".
With added fish you will have added cleaning of filters. Make sure your filtration is more than enough.
