What do you feed your African cichlids?

Im feeding hikari cichlid excel mini floating pellets...and delicasea super veggie flakes...which i believe are excellent as they are made from fresh seafood and vegetables..they have spirulina in them too...but do you think i need some frozen food like brine shrimp for extra protein aswell? or is this diet ok? I have Phseudo. esthrae Melanochramis johanni and Electric yellow labs..they are all juvenile...
