Hey Matt, IME the trick or method that has worked best for me with Centropyge species in a Reeftank is to feed well and have many corals. I think that all of the Angels will at least nip/sample your coral occasionally... it's in their nature. As far as hardiness goes I believe most to be quite hardy and collection procedures to be the determining factor to their survival rates. As I also always preach, try to purchase only juveniles. Better for the species as a sustainable population and for us Reefkeepers as to acclimating to prepared foods before they are set in their ways in the wild. Or purchase one that has been in captivity for a time.
Cheers, Todd
