Bubble coral deflated

Kilo · Apr 20, 2017

Hi fellow reefers,
I have had my bubble coral for over one year and for the past few days its have been deflated. It used to open up as big as 10 cm diameter. I decide to take a picture after lights off and noticed some white stuff in its mouth. See picture

Pls advice what this is and what can i do. Its my favourite coral and sad to see it like this.

Note: all my other corals are doing good.
My nitrate is 1, pO4 is 0, Ca is 400, mg is 1300, kH is 7.7,

Thanks in advance

Check your ammoina.
Any other changes or additions? A recent water change?
Recent GFO addition?(po4 0)

I can try to check ammonia but other corals are doing good with feeding tentacles out fully opened.

Nothing new was added to the tank. Last water change is a week ago.

But i did add a red gonio two -three weeks near to the bubble coral but not side by side. Could the gonio stunk the bubble?
