These orange colorations around the head and face in my experience, are pretty typical with P. scalare angels and show up as a fish matures. The greens/blues are typical as well, especially on the fins. Not all fish mature the same though so some fish may have more color than others. All of my P. scalare angels are maturing with this orange coloration and blue fins, my P. altums are only getting the blueish fins. This is just my opinion and not scientific fact so take it for what it is. Under P. scalare I have marble, silverlace, koi, black, smokey leopards and albinos angels and all my fish with the exception of the black, show these colors. Even my albinos are getting some orange. :?
