You know what about year ago i had the exact same thing had this open brain electric green for over a year one morning it looked like it was hurt or something kinda closed up( which was rare) didn't really think anything of it check water everything good, no other issues with corals or fish

Next morning it was sloughing off tissue and a goner no idea why nothing to cause it no fish picked it or anything , i fed it couple times a week idk

I talked to some others and some say they can get a infection but I'm not sure if thats true or not

I chalked it up to some times in this hobby shit dies ..

i would double check your water and stuff to make sure nothing is array
