Bubble Coral
 

My bubble coral which is attached to a rock fell into the sand and landed on the bubbles, it may have been there all day while I was at work, well now half the bubbles in the middle part of the coral are gone and it looks as if they died off, will there regrow in the damaged part of the coral? In all the coral does not look good. Any one???

They are pretty hardy and can usually come back from just about anything, except for maybe an ammonia spike.

If conditions are good in your tank it should heal up in time. It will probably look pretty rough for a while but don't give up on it.
