I couldn't agree more! Well said.
Last month i bought beutifull (large) P.navarchus (or is it now E.navarchus?)... This angel is stunning! It took me a whole week just to acclimatize this semi-adult fish to my mostly SPSP dominated reef, and my Zebrasoma xanturum didn't help too much with it.
Nowdays Majestic angel swims and eats with other tankmates, and my polyp expansion isn't as good as it used to be - but who cares?! Angel nips at polyps some time, maybe he nips at slime, as LemonLemon stated above, but truth is this amazing fish can be kept in SPS tank, IMHO.
My advice to ppl who want to have large angels in their reef is: buy the fish when you have large specimens of Acropora in your tank and enjoy in your new angelfish!
