Can you locate the source of the problem. Did you add new unquarantined fish or something. Problems like that generally don't just pop up, so if you added a new fish assuming it was a reputable LFS, see if you can go back and ask what diseases they've had in their angelfish tank so you know which one.
Hemorrhagic Septicemia is more rare than fin rot from my experience however both are severe debilitating diseases. I recommend treating for both however make sure the medications you put are compatable together.
