Too many fish in 90 gallon?

[shark230]

I have a new 90 gallon reef tank. I have a 5 inch yellow tang that I am going to add at the end. I already added royal gramma.
Can I add 3 red fin fairy wrasse, royal gramma, and 2oscellaris or is that too many with yellow tang in 90 gallon? Will they get along?
I have had yellow tang for 4 years and is being stored at pet store now until ready to add to tank

I have quite a few fish in my 90... 4.5" Blue Tang, 4" Copperband Butterfly, 3X Lyretail Anthias about 3" each, 3X 2.5" Pajama Cardinals, 2X Springeri Damsels, 2X 3.5" Bar Gobies, and a 4" Melanarus Wrasse. I'm still having problems maintaining nitrates. I am thinking about adding a few Blue-Green Chromis or maybe another Wrasse.
