Maybe the picture was flipped? I don't see any wrasses on the right of the Copperband? To the left there is a Leopard wrasse,
Macropharyngodon meleagris a beautiful fish!, I 've had one for 4 years now.
I'd agree with you on the Anthias,
Pseudanthias hypselosoma they along with a few other species often come in as assorted Anthias or Pink Anthias. I think I've seen them come under a few other names too, but I can't remember. Again nice fish, I hope they all survive your emergency tank relocation.
I have a friend that would gladly babysit your red sea tang, but I don't think he would want to give it back!!!!
