If you like the Maculosus, I'd recommend the Asfur angel instead. They are from the Red Sea, so quality of the fish is up there. But for a 125gal, the Asfur will stay smaller. Mac's grow to be a pretty large angel, Asfur's stay smaller, about 10" max, have seem to have a very slow growth rate.
For the Cortez, have you seen the adult? I hate to call a fish an ugly duckling, but an adult Cortez is just not I'm angel I'd have when there are so many other more beautiful angels out there.
