This coral is very hardy and has a very high chance of surviving. First thing you have to do is stop moving it leave it in one spot and don't bother it. At night you might be able to see the tentacles, if you do try and feed it a meaty food like mysis shrimp. Try and keep your tanks alk, cal, and mag stable.

Here are pictures of a candy cane that I have saved:
