Anyone here ever keep a blue line or blue ring in a reef?

Fish psychology, where were they captured, how old were they when they where captured, were did they originate from, how much do you feed, how big is your tank, what would its companions be, and does the fish feel like it. Annularis like to pick on clam mantles, but blue lines from Taiwan are RELATIVELY (stressed) reef safe.
 
When it comes to large angels you really need to go into it expecting the worst. Your clams are food, and depending on the species, individual, how well-fed it is, and how it feels that day some of corals could be nipped at/eaten. It's a real cr@p shoot.

That being said, I had a friend with a nice 250 reef that housed a beautiful adult Emperor angel that never touched his T. maxima (last I heard).
