Which saltwater fish should I add to my tank?

[ac3131]

I have a 46 gallon tank with 100lbs of live rock, coral, a clownfish, yellow tang, cleaner shrimp, emerald crab, mexican turbo snails, and hermit crabs. I want one more addition that will bring my tank together. Any ideas?

a Blue Tang or some Wrasses would be nice. Or even just some feather dusters
