Brown Jelly Disease?

[Reefer_French]

Hello, I was wondering if anyone can confirm that this might be brown jelly disease. I noticed this goniopora have this spot but only half as big yesterday and then saw this today at the end of the day while feeding the corals. I saw some flesh kind of drifting or hanging off of it and was wondering if it looks like brown jelly. I saw some other corals looking a little weird, but it was hard to tell because the lights were going out at the end of the day so could of been just that. If so, any potential treatment options? Thanks.
I also have 4 other gonis on that rock and they’re all doing ok.
