Yuma? Mushroom balloon?

[RedSea50Gang]

I have had this mushroom for over a year I think it’s a Yuma. It has always had one kind of bigger little balloon (for lack of knowing the actual term). This morning I noticed that bigger balloon is huge and the rest are a little shriveled. What’s up with it? Looks healthy otherwise... is it norma to have one giant inflated one??? See pics

We call them bounce bubbles. There's nothing to worry about as it doesn't affect the health of the coral. Your mushroom looks a little oblong and might be close'ish to splitting into two! Believe it or not but that bubble makes your coral worth more.

And could you take a picture of this coral under white light?

I love me some bouncing yumas.

Often but not always triggered by light light. Congrats.
