CORRECTION. The only imperators with orange tails are from the Christmas Islands. NOT the Red Sea. Yes, the ones from the Red Sea have tails that are slightly darker, but they aren't Christmas Island Specimens, by any means. IMO, it is worth the extra few dollars to purchase Imperators from the Red Sea, because they do have better color than Indo-Pacific Specimens, and they are hardier, because they are handled much better on the way here. Plus, most of the Indo specimens come from the Phillipines and Indonesia, where the usage of Sodium Cyanide is quite common. Hope that helped...
