Urgent Torch Coral Dying?!

It looks like our torch coral isn't doing to well. We recently moved it to a new area in the tank because we added a hang on the back protein skimmer. One of the heads had previously died, but we left it as is. Now it looks like a second one is starting to die and you can start to see a lot of the skeleton. I also noticed that it seems to look like it is kind of "rotting" on the bottom of the base. The coral also had brown coming out of its mouth, I couldn't tell if it was poop or brown jelly. The coral seemed to be doing fine yesterday, but something must have happened today while I was at work.

Please help with possible solutions to revive our coral! Thank you in advance

I have uploaded pictures to my google drive of what the coral currently looks like and what it looked like yesterday.
