That's like saying since there is no species named saf1, or your actual full name for that matter, that therefore you or your genes don't really matter/exist, and we should disregard pictures of you or family resemblances etc. The fact is there are real differences between different color morphs of the same species of Acropora, just like there are real differences in people, that fact that we don't classify them scientifically is irrelevant. Keep in mind that I agree with you that this particular coral is way overpriced.
