What makes you 99% sure it is Elutherobia vs Minabea Alderslade?
Well I can't be 100 percent sure but it looks like the pictures and the polyps stick out 1/2 an inch from the coral. Not in this picture but I have seen them. In a Minabea the polyps are tight to the coral. Rumor mill has it you might have some yellow ones also? Your red ones are nice looking.
