Thanks to both of you and checked of course both species. Both species looks very similar as juveniles but from pictures I found I quest the Queen angelfish looks to fit a little better. For the moment I leave the title as being still unknown untill there is more surtainly about the real ID.
I would say that this is a Queen Angelfish (Holacanthus ciliaris). Notice how the first four lines on the fish's body starting near the head are slightly curved and the last one near the tail is (somewhat) straight. For juvenile Bermuda Blue Angelfish, the first three bars near the head are curved and the last two near the tail are straight. For juvenile Queen Angelfish however, the first four lines are curved and the last one is straight. Therefore, this is a Queen Angelfish and Tim May's ID is correct.
A search online and in my books indicates there is some variation in the 'bending' of the lines, and while I'm not convinced this is not bermudensis as I suggested, I agree it is looking more like ciliaris than I first thought. At this point I'm not 100% on either.
