It is true that stress can cause fin rot. Nevertheless, your fish did not get fin rot because of stress. For instance, fin rot due to stress occurs when a fish is cramped in a small space. Your angel was in a very large tank. Furthermore, fin rot due to stress can occur with bad water quality. Your water quality was not bad enough to cause fin rot.
Every time one of your fish gets ick, you should always assume that all of your fish have it if they are in the same tank.
