Though some of us have differences of opinion on the tank size requirements for tangs the reefer who held a regal tang in a 34 gallon tank should be reported to the SPCA.
The chances are very high that you will have a fight to death when you introduce both in the same tank because of their size, colouring and species. The stress will weaken them and some of the other fish in the tank as well. You risk an ich outbreak. You do not know the condition of the new tang. I would not take the risk.
If you chose to add the fish do it in a darkened room and leave he lights off for a couple of days. Feed from both ends of the tank.
Thanks for sharing your concern
