I would swap the Afra for the maingano. Cobue females are pretty drab just like peacocks and you may end up with a few to many dull fish in the one tank. Besides that they may not get along with the saulosi.
I would add the maingano and call it stocked, considering that both the Acei and Jakes will grow beyond 5" as will the Maingano eventually
