Need new fish addition advice

[Alexa&Walt]

Good Morning everyone and happy Easter!!!!

Presently we have the following (but i'd like to add one more fish)

o Kole Tang
o 6-line Wrasse
o Diamond Watchman Goby
o 2 each Clownfish
o Skunk Cleaner Shrimp

65gallon reef tank with various corals (LPS)
VHO Floursecent lighting

I'd like to add just ONE MORE FISH.....

Perhaps a blue Tang or a Coral Beauty or a flame hawkfish or a blue Damselfish????

Does anyone have any recommendations as to what I listed or alternate fish. I'd like a little more color in the tank.

My concerns:

Compatability....everyone gets along well as it is.
Tank size.....can I accomodate one more fish???

If you want to keep your shrimp then the hawk is out of the question. My thought would be the coral beauty or have you ever considered Chromis, they are a lot mellower that damsels.

Don't Chromis require schools of at least 5 to do well?

Id lean toward a reef safe angel, or a flasher wrasse.
