cichlid stocking

Hello guys, I've got new 55 gallon tank after cycle (40" \ 15" \ 21" ) I want to put inside central american cichlids.. I thought about 2 different setups, what do you think of them? 1) Working pair of Rainbow cichlid (Archocentrus multispinosus) with more 2-3 large schools of tetra \ neon. So...

My 4 foot long tank is all set up and cycling, the fish should be ready to be added in 5-7 days, and right now I'm just wondering on exact stocking numbers. Heres what i thought. 7-8 juvenile peacock cichlids 3 electric yellows 1 brittle nose catfish
