Wonder the bro who got the Hawaii emperor could kindly post a pic.
Did some search. Apparently emperor angel is never found in Hawaii seas.
The one or two spotted by divers are most likely released there through aquarium tanks...

Stu Ganz and Bill Stohler both sent me photos of this Emperor Angelfish, seen by each them individually on May 9, 2010, in a swim-through cave at Sharks Cove, Pupukea, O`ahu. The species is native to coral reefs from Africa to the Line Islands and French Polynesia, but not to Hawai`i. Given that it was seen at one of O`ahu's most popular dive sites, the fish is almost certainly an aquarium release. There is, of course, the more remote possibility that it got here naturally. Such things have happened. In 1948, before the advent of the commercial aquarium trade, an adult was captured in a trap off Ewa at a depth of 90 ft. But there is no evidence that a breeding population has ever existed in Hawai`i.
If this Pupukea fish arrived naturally, it would likely have grown up in the area where it was photographed. And if a juvenile Emperor Angelfish (even more spectacular than the adult) had been present last summer, it would certainly have been noticed and photographed by dozens of divers, and the word would have certainly got out. Of course, in the unlikely event that it did grow up here unnoticed, it is questionable whether such a fish could survived the onslaught of this winter's waves.
As a matter of interest, another Emperor Angelfish lived for some years in Honolulu Harbor, near the Falls of Clyde and could easily be seen from shore.
