i have a mix of alot of different types of LPS and my pair of clowns are model citizens when it comes to them. they host in my elegance coral but i wouldnt recommend getting an elegance as a beginner. +1 for duncans, id also suggest for beginners mushrooms, zoas, acans, GSP, xenia. alot of people will tell you not to get green star polyps or xenia coral because they grow so fast, but if you isolate them then its fine especially because IMO xenia are one of the coolest corals to watch, always grabbing.
