Wall hammer emergency

[reefer2000]

Het reefers! Hope everyone is safe during this pandemic. I bought a green wall hammer coral about 1 week ago from corals.com came in well packaged. Aclimated it to my tank did a coral rx dip and put him in all was great, opened up fully the very next day. After 3 days my blue legged hermit thought it was a good idea to nibble on the tenticles, so the outcome was that the coral shrivelles up and did not open, so I tried feeding it and it excepted the food but spit it out eventually after some time. I got rid of the blue hermit, took it to the LFS. Then its been 4 days already its shrivelles up like this and does not open anymore, I dipped it in coral RX but no signs of getting better. I put it in a very low flow area since I have been keeping euphyllia for long time but only branching variety not wall so I am kind of new to this. Any advise or help is apreciated.
My water params.
Calcium 410
Mag-1350
Alk- 8.5
Nitrate-20
Phosphate-0.03

How old is your tank? Have you done a parameter check for Salinity and temperature ?

What's the lighting like where it has been placed for the past few days. I wonder if the other frag you had next to it upset it. Good luck
