Brain Coral issues

[reef insane]

Ive had this piece for 4 years. Never had an issue. Parameters and water quality is perfect. Temp alkalinity ph calcium magnesium good. Calcium reactor. Dosing. Etc. sps and lps all flourishing. I don't get it?? Brain has been closed for 3 days now. No skeleton showing yet but I'm getting concerned. Do these things molt or go through moods? Sorry typical blue iPhone

Anything near it that could be stinging it? Especially at night?

Any changes/additions recently? New fishes?

Hey Jen. Good to hear from you. No it's been isolated ever since introduced to the tank. There is a very small piece of Kenya tree on the same rock but it has never affected it. Absolutely no additions. The brain used to be's swollen and superhealthy. I don't get it. I cut a 1 L Coke bottle and put it over the coral and feed itdirectly hoping to get some response. Nothing

Any additional water flow changes that might upset it?

Not at all. As of today conditions are the same except it does now open a little at night.
