Giant Green Duncan advice

I've had a colony of Duncan's for about a year.  I love these corals.  They've always seemed like the toughest corals in my tank.  They thrived through phosphate spikes, large temp swings, questionable water from a spent RO membrane...

Then I had a nasty Majano Anemone outbreak.  I added a Bristletail Filefish (also called Seagrass, Jade, Aiptasia eating Filefish) to remedy the problem.  The Filefish cleaned up the Majano's like a champ.  He then moved onto my Zoa's, Leather's, Monti Caps and Duncan's.  I'm pretty sure most of my corals will recover from the damage that he caused, but my Duncan's have been completely withdrawn for a few days.  I can still see the tips of they're polyps.  So they're not dead yet.

I ended up doing a complete teardown of my tank to get the stupid filefish out after spending a few days trying to catch him.  I removed most of the rock and corals.  It was a giant pain in the butt.  Everything is back in and looks like it survived the ordeal.

I'm looking for any tips to help with the recovery of the Duncan's.  Should I do anything other then keep they water quality top notch and target feed to speed they're recovery?

That's what I thought.  I changed out all of the filters in my SpectraPure RO/DI unit yesterday and flushed it out.  New Ro membrane, sediment filter, carbon filter, DI filter and DI silica filter.  Emptied my 80 Gallon holding tank and let it refill with the new filters.  Now I can stop hauling water from my LFS.
