Pink hammer shrinking... help!

[kris2001]

Someone gave me this beautiful pink Hammer six months ago it was very well cared for it opened up well and it was doing great now it's shrinking ...

the video is actually two heads it doesn't come out it is under metal halide lights it's getting enough light , a gentle flow . (Sorry i haven't cleaned glass in a week)

I don't know what's wrong with it I don't know why he's not expanding ,he used to expand about three times that size any suggestion? by the way it's not a wall hammer but if anyone has had this pink Hammer before please let me know how to care for it thanks.
Also...
All parameters are ok, i have other euphylia doing well. I also feed the DT
Reef roids every other day and feed the fish daily.

Hi, seeing some bad tissue recession on the left side. Could it be Brown Jelly Disease? I have found the hammers that are that extremely curved on the tips to be difficult to care for and easily susceptible to BJD.

Any easy cure for brown jelly disease?
Will high flow help? Iodine?

Thread on how someone fixed it. It’s possible to fix, but not reverse, the coral has to get rid of the BJD then regrow the skeleton. It’s the velvet of the LPS world, a very fast killer
