Hello
I just noticed that part of this coral is attached to the rock and the bottom part is stretching and looks bad
I tried to remove it from the rock , but the coral is super soft and it is really stuck to the rock
What to do now
It looks like a "xenia". I have some xenia and it will stretch and grow, attach itself to other surfaces. So much so, you may wish you didn't have it someday. No action required.
The xenia I have has to be weeded on a regular basis. Otherwise it will take over a tank. Many reefers consider it a weed. I keep it and prune it and have no problem with it. It was my first coral as well.
