That one looks more like a red planet type of coral. People say that red planet is A. Hyanthicus, but I do not think so. If you look at the two photos closely, they have similar color and plate, but the one in the original post has must larger tips and more of them. In any case, it is a beautiful coral as well.
Now that I look again, I would need a closer shot, but the original could be A. Millepora that has grow in a tabling form.
