Duncan coral black polyps

[BSTurbo6321]

This morning I noticed my Duncan is not opening all the way and it’s polyps have black ends. Any help would be appreciated first picture is a couple days ago and second is today

corals close up at nights, and corals look brown in their natural color. Your duncan looks normal to me, it will color back up when the lights on come.

It’s currently mid day and full lighting, picture isn’t take very well I get another

If the lights are on and the polyps are brown, it might be low lighting. What type of light do you have on what intensity, what tank size?

It’s setting mid tank and is lit by ai primes at nearly full intensity and 70 whites

I see two different lighting in two pics.
Of course they would not look the same.
