I have an exquisite and a Lubbock's wrasse in my 75. I picked up both locally. (Richmond, VA) I hope to add a Carpenter's as well.
I've seen some red velvet wrasses locally and a PetCo not far from me has had a female flame wrasse for quite a while. I've also seen the Lubbock's there (two different color morphs).
I've also seen orange backs in Virginia Beach, VA and Debelius wrasses in Lancaster, PA for sale. I've seen Scott's fairy wrasses a couple of times around as well.
It's not a flasher or fairy wrasse, but I also have a melanarus in my 40. (Got him in Silver Spring, MD.) He used to live in the 75 but I had to remove him due to aggression issues.
As others have said, Live Aquaria stocks a lot of different species.
