Dying Duncan...ideas?

Everything else seems fine... no other stressed corals. This guy got knocked over by a snail a bit over a week ago, things started to go down hill a few days ago, several heads closed, then turned dark...now spreading. I am not seeing pests. Thoughts?

Brown Jelly Disease? If this is the case you might want to break off the two polyps in the foreground and toss the rest.

Will this hurt other coral?

I've never had it spread from one coral to another, but then again I don't have a whole lot of experience with the disease either. Once it showed up I would just toss the coral and be done with it. An Iodine dip or something like Coral Rx might help, but like mentioned above I never took the time to find out. Hopefully somebody with more experience with this disease will chime in here soon.

Mine started to brown jelly within an hour for some random reason
Did the reef dip and saved most of them
Good luck
