What is this on my Acan irritating it and seems like eating it?

I found this on my Acan the other day. I immediately pulled the coral and dipped it in ro/di water which seems to have helped. Definitely shocked the coral a bit but the pest is gone. It seems to be directly attached to the coral and it was circular, soft, and jelly like.

Almost looks like “ Brown Jelly disease” that plagues lps. Treatment for BJD is Ciprofluxon? (“Cipro”).
If it returns I would pull and treat it with Cipro- and watch any other lps present for similar symptoms. It kills quickly if not treated.

If it's brown jelly it will blow off easily

Also, that coral looks like it's almost dead. I'm not sure it can be saved. I'm sorry.

I used to because that was all I had in hand. It does seem like it has mostly died but some parts are kinda coming back. I am gonna keep an eye on it. With ro I know it’ll kill any pest so I just wanted to do a quick dip. Some places even recommend dipping all corals in ro but I try not to.
