Mine is currently in with a angel that is hazing him pretty good, a cleaner wrasse, a royal gramma (that was in with him in the established tank I bought them from) and a clown goby...   He eats mysis, and picks at the rocks, but must not be picking at aiptasia as I don't have any in my nano.. 
He has become my favorite fish out of the group.  VERY active after lights out..
