I have four keyhole cichlids in a 55 gal and they are painfully shy, to the point of crashing into sides of the tank, and I think if I didn't have a lid, a few would have jumped out, just by me opening the door to the fish room. Beautiful fish, and after I sit still they'll come out do cichlid things, but still. As juveniles, they'd be out and about, swimming with the rainbows in their tank, but as adults not so much. For a featured tank in a prominent part of the house (which your tank definitely should be) I'd go with something else. Food for thought.
