I've got the same size tank - and it may be that I'm willing to accept a bit more risk to corals than some, to have some amazing fish on the reef.
I've got a blue-jaw triggerfish who's a real charmer - even if he does dress like a girl. (A risk to smaller shrimp, though he leaves my cleaners, blood-shrimp and peppermints alone.)
I've recently purchased a Quoy's parrotfish who's being remarkably shy and not coming out to eat for just over a week now. When he does, all the nearby rainbows are going to be jealous. (Everything I've been able to find about this parrotfish indicates that they stay between 8-10 inches long in an aquarium, and that they're completely reef-safe - though not at all safe for acrylic tanks!)
I'd love to try a regal and a majestic angelfish, powder-blue and achilles tangs, and a yellow long-nose butterflyfish, all of which have better-than-average records of reef-safe-ness for their family groups, and all of which are beautiful in color and finnage. In order to someday do that, I'm thinking that I'll probably run my 220 fallow for 76 days while re-quarantining all of my existing fish from the 65, so that those tangs and angels don't come down with something nasty.
