Goniopora question.

[JoeLogan24]

Hi! I have a green goniopora that is tricky to me. Some days its all opened up and pretty. Some days half of it is open and the other half closed or barely out at all. Some days all of it wont open up. Its random from day to day of what its going to do. Every other coral in my tank, even my purple goni next to it, are all always open and happy. I havent moved it because it does open up all the way some days like its happy and i dont wanna move it and it never open again. I havent changed the flow, lighting, or chemistry (other than weekly 30% water changes and reef roids EOD) so im at a loss. Any help would be appreciated.

Oh the the reef is 1 year old this month so we are celebrating its birthday.

Do you have anything that might be irritating it possible a fish or invert that is picking at it or another coral that would sting it?
