While I cant comment on the Fox coral, I can say leave the Tree coral alone, it's normal for it to be looking "hungover" like you said.

I've had a gorgeous Xmas Tree coral in my tank for about a year now. Every once in a while it darkens in colour, slumps over and looks like it's on it's deathbed for a day or two. I knew it wasn't water parameters as I also have a smaller frag of it sitting right next to it that would still look terrific.

So long story short, couple days later the larger piece is back to normal and lighter in colour and fully expanded.

Just something they do I think?
