I have a small frag with about 10 little heads on it...poor thing got dragged into the sand bed by my pistol shrimp and sat there a few days before we noticed. Its been rescued and glued back onto the rock work but they have remained closed for maybe 2+ weeks now. They haven't melted away, just closed, but you can still see just a little color in them.

The zoa around them are all booming...so I'm not worried about parameters/light/flow etc. These just got traumatized face down in the sand for days.

Question...do I leave it and see if they open up eventually? Or is this a lost cause? Any experience with frags opening up weeks later after trauma?
