Single hammer coral closed

[coastalnanoreef]

I have a pretty much hammer only tank. Every hammer looks amazing except for 1. The past month or so this coral hasn’t opened up. I have no idea what the problem could be. I will attach a picture of what the coral used to look like vs now. Any help would be greatly appreciated!

Are the corals directly next to it bothering it?

No. I’ve moved it 2 times now.
