UPDATE:
The order from liveaquaria came in.... minus 1 of the 2 fish I ordered. The sailfin tang is on backorder. 
I added a Kole tang a week ago today knowing that the Desjardini Tang was not shipping. B&B had a really nice looking one in stock. The Powder Blue showed up on Tuesday. No agression between the tangs and everyone is doing really well. My Coral Beauty tried to be the boss for all of 2 seconds with the Powder Blue. I am running my UV sterilizer and it has helped to keep the dreaded ich from popping up.
I am really happy with the Powder Blue from Drs Foster & Smith. Once in the tank it immediately settled in and was feeding off the rock. I hope to add a Orange Shoulder this week and get the Desjardini Tang in as well.
Thanks for all the imput!!!! Tangs are addicting!
