[Hydrostatic]

Hi all. I have just purchased a candy apple scolymia a couple weeks ago and everythign has been going well. Yesteday, I was spot feeding it with some mysis shrimp, when one of my smaller hermit crabs(about the size of a peanut butter m&m) decided to climb the coral and get stuck in its tentacles. There is a bulbous area in the center of the coral, where the shell remains. How do I get the shell from under the coral's skin? Thank you!
