It's debatable, some people say anthelia pulse, others say no... I can say I have never seen anthelia pulse
What color is it? anthelia typically has a duller coloration, white,grey,browns(though some can be pinkish red or even blue).
Anthelia generally has a taller longer stalk, and the hands(tentacles) are usually longer and more pronounced.
Google Waving hand coral and Pulsing Xenia, You will see they have differences...
Though it doesnt really matter, I was just curious. I personally like pulsing Xenia, and think it's worth keeping.
