I have a Majestic, Blue Line and a tiny juvi Koran. There's absolutely no aggression among any of them yet (the Blue Line and Koran are new, but went into the new tank soon after the Majestic). I don't have a lot of corals and no clams, although I want to change both of those things. None of the angels pick at any of the corals, although I've seen the Majestic pick at stuff...probably bits of food or algae...that is in amongst the zoos and button polyps. I'm keeping my fingers crossed...but like others have said, the angels are possibly the coolest things in the tank, so if I can't keep a certain type of coral, so be it.
Btw, the Blue Line in the store was in a tank with frags of various things including zoos and hadn't touched any of them. He did have a close encounter with a longspine urchin that left a small would in his side, but it doesn't appear to be bothering him, and I got him "cheap" as a result. I'll try to post some pictures later, although I have a microbubble problem that makes everything look like it has ich in pictures.
