The photo displayed here for Queen Angelfish, Holacanthus ciliaris shows an atypical "crown" for this species. The fish is probably a hybrid of H. ciliaris and H. bermudensis. I am currently raising an example of this same hybrid in an 180 gal. tank and have a series of photos showing its progressive development over the last year and a half from what appeared to be a juvenile "Blue" to the immature stage looking like the fish in your photo. Please contact if you wish to display copies.
