Open brain coral problem?

[Ryan15236]

I was looking at my brain coral and it has an area or two around the edge of it that is kinda like pinched in towards the skeleton and has some kinda like white mucus/fleshly strings from it. Not sure what it is. Had this guy for 3 months and it has always done well for me. Not sure if it's an injury or what. I did notice a scarlet hermit around the brain for awhile today so not sure if it did it or not

Hope it bounces back! Had this coral for a few years!

You could do an iodine dip.I'd raise Alk to around 9 or 10 if your tank is lps.

Idk what it was doing. The next day is was looking full and as fluffy as ever. Just had me worried because it literally looked like worms were coming out of it.
