Single goniopora staying closed

[QCPD16]

About 10 days ago I noticed one of my 5 goniopora’s was looking a little deflated. Two days later I noticed it staying closed up 24/7 while all 4 other Gonioporas in the same garden were looking fine. Does anyone have any insight on this?

some more info-

-Tank is 14 months old and has had no recent parameter fluctuation including lighting and flow.

-Triton method with no major issues on ICP test done 1 week before issue was first observed.

-All other corals are doing fine and growing noticeably every day- including the other gonipora right next to the issue one.

- I’ve had this goni for about 5 months and it was 1/4 the current size when I purchased it.

-I noticed one of my clown has been hanging around that area more often now, but I have not seen him touch the Goni. The clownfish does however seem to be a little protective/aggressive in this area lately. The Goni stays completely closed at night though, while the others stay open, and the clownfish is fast asleep on the other side of the tank. Could the clownfish possibly be pestering just this one and leaving the others right next to it alone?

It's possible the clown could be pestering it, yes.

I dose manganese daily and I don’t have this issue anymore.
