Green Finger Coral

[Cunningham]

I have a green finger coral and it's green and opens nicely and my buddy has two of them and we both got them from the same person and his both turned reddish pink but look nice and open but not green anymore. Why is that?

Probably the difference in lighting of his tank to ya'lls.
