What Jbadd said... it's a chronic condition that can be reversed in the early stages, but alas my set of orphans (I have 5, from 4 different keepers), were in the advanced stages of it when they came to me.
There's a lengthy thread on here (well there are many discussions) about a theory about its causes and treatments. I won't get into that here, as it will derail the thread, but my specimens have severe disfigurement, their dorsal fins are partly missing or entirely missing, which drastically changes their appearance. Rather than be euthanized, I took them in and I keep them away from intact specimens (the ailment isn't contagious) so they don't get picked on by others. They'll live out the rest of their lives with me - they're good algae pickers.
Back to the topic at hand... I did once introduce a yellow tang to a tank AFTER a flame angel had been there a while. The flame killed the tang (I'd have put money on the tang winning that argument), the next day.
Like I said - it just depends on the individuals. Sometimes they get along, sometimes they don't. Choose specimens carefully and wisely, and my recommendation would be to introduce them at the same time, that way neither has a home turf advantage.
