Elegance closed for a week...what to do?

[Phyber]

I've had this elegance for a little over a month and it's always looked great. I got some new corals in and out a galaxea frag a bit too close and it's been like this ever since. I moved the galaxea far away but no change in the elegance.

What can I do?

Before and after....

Look for any pest, also maybe an iodine dip. Keep it low flow and low light to help it recover.
