Tangs not meant to be or what???

Well the other option is to wait for all your fish to die, wait another 72 days then get new fish.

If you have room for a reef tank you have room for a QT tank. You may need a bigger one due to the fact ich made it into your display but you can run it just for this period then sell the tank and get a smaller tank to use when you add one or 2 or 3 fish at a time ect.
