Don't be discouraged. It really is individual personality of each fish. You can try another Coral Beauty (perhaps smaller) again.
Alternatively; there are other Centropyge angels that are similar that you may want to look into:
Rusty Angel, Midnight, Blue Fin, Golden Dwarf, Flame, Potter's, Lemon Peel, etc.....
Take some time and research (some are more 'reef safe with caution' than others.)
As an aside: Chromis are kind of weird (at least for me). I've had them spontaneously disappear and die without a specific known reason (predator, disease, internal hierarchy fighting) in the past. I've already accepted the fact that they aren't as hardy as other fish.
My 2 cents
