One thing I learned a decade ago when I was first putting fish into the Aquarium - There is very little agreement among "experts" regarding some saltwater tropicals. Several species are indistiguishable from each other as juveniles, and there's discussion about whether they are even different species at all. Just do a Google image search for "Koran Angelfish". I've never even seen an example of the straight-bar version that you posted.
