I have had this pineapple coral for about 3 years. Within the last month or so it has developed these "bubbles" of flesh. Its almost like its flesh has become disconnected from the skeleton. What could cause this and is it a reason to worry? There has been those two (big one on front, smaller one near back) that you can see in the picture, no changes though, they havent grown or shrunk or changed since they appeared.
