Help!! bubble coral

[Dtfnemo]

Hi guys I noticed some part of the skeletal showing on my bubble coral, it looks dark like if it has been sposed for a while.
The coral looks healthy, it only shrinks at night when lights are off and every now and then in the morning but it does not look stressed.
Is it possible that it heal it self and that portion of the skeletal is just going to be exposed? Should I dip it? If dipping what would be better coral rx or revive?
It really don't look stress, it eats a lot and is puffy so dipping might stress him more than help him right?

I would leave it if it is fluffy and eating. Let it heal itself. Yes, stressing it or risking tearing it is always a concern with those guys. More damage than good.

Yeah that's what I was thinking I don't wanna loose him, those pictures were taken when the lights go off, that's really the only time when he shrinks and you can see the skeletal exposed
