Problem with acan

[Sitthanon]

So a few days ago one of the head on my acan started to deflate and not puff up. The center of the coral is puffed up with arms out but the rim is not puffig up. Anyone know what to do?

My other acans are doing fine and

Alk:9
Cal:410
Mag: 1320
Nitrate: 5
Phosphate: 0.07

Is the acan on a sand area? Are there any torches or hammer corals with in 8 inches of that side of the coral?
Looks like the coral has been damaged.
a bath in lugol’s solution will be need if you see a brown bacterial infection.

Its on a rock at the bottom of the tank, one acan near a 3 inches away

2 clownfish 1 goby and one pistol shrimp in the tank atm.

Cant really see anything brown, the rim on it just wont inflate

Is there any algae growing on the edge? That will cause them not to inflate and start to recede

It’s skeleton isn’t showing on that side is it? It may have injuries at the area where the skin is at the skeleton. It could bounce back just keep an eye on it.

Can't see any. I can see the flesh that are supposed to puff up. half of the acan are puffing up but not the bottom half
