If the blue tang lived through being stuck in a piece of live rock, thrown on the deck of a boat, rinsed off, being around the die off of the live rock, then put in a lFS, then in a new tank-he may still survive. Not being mean, this post is comming from someone who did not feed his flame hawk for two months (stayed fat) while trying to get rid of the $%^% hair algae. Good luck!
