Clown hosts bubble

[n8ball2013]

My GSM is hosting my bubble coral and the bubble is not looking to enthused about it. is this something to worry about? usually the bubble is about hte size of a mini football but since the hosting it only opens up to about the size of my fist. Dont want to lose this thing it is pretty much the centerpiece of my tank.

how long has the fish been hosting it?
my clown hosts a sunflower coral, and the first day the coral didnt really like it and he woulndt open up, but the day after and on the coral has opened fully and the clown still hosts it, give it time, if not u might have to either get a new coral or remove the clown but i think u should leave it b
