Everyone is going to ask for parameters and conditions so might as well post them. Could be a lot of things from a parameter being off and eventually the Duncan got tired of it to something nipping at it. I had a Duncan completely close up and suck way in for over 2 years but it never died so I left it alone, eventually my filefish had jumped out of the tank and instantly the Duncan came back...

What's you Salinity? I suspect not bad given the others unless you're dosing. But I had my duncan's go into a very similar state for about 3-5 days, after my refractometer got out of whack and read way off. I was down to about 1.020 after a water change because reading it at 1.025 was actually closer to 1.015....awesome lol Also if you haven't calibrated your equipment recently, there's your reminder 
Edit: Beautiful tank, if everything else is still looking that good then maybe it's popping out a new head? I've heard some will kind of "retract" while doing so for a bit but I've not experienced that myself.

Thanks for the reminder lol. It's 1.026. Its just strange. She was in my very first shipment of corals of a few Duncans n zoas and was the only one to thrive. Have seem some that look similar that are just splitting evidently but...idk.

It's been like this 3 days you said? How heavy is the flow on them? Mine will get pretty ticked if I hit them directly, but also kinda angry if I dont get them enough too. I've found "low-moderate" makes mine the happiest. I use an MP10 with reefcrest so it gets a few shots of good flow at times too. Just curious, unlikely flow related for 3 days unless it's really getting hammered.
Edit: Can you get a side shot of the flesh? Curious if it's retracted much or not. If that's looking fine, then I'd just wait it out.

Yea if the flesh on the underside isn't receeding, then I don't think it's really truly in trouble. Once that starts pulling back, something is definitely off. Mine was receeded to the point I thought the whole head would pop off after that "fateful" water change. Now they're huge and happy. I'm sure they'll survive, just keep an eye on the flesh on the side more than what the polyp mouth/tendrils is doing right now IMO.
I'm still learning more about LPS, so my word is by no means gospel lol Just speaking from my recent experience. This all happened about 2mo ago for me.

Thanks! Yeah as long as there's flesh I'm not overly worried and everything else seems very happy but of course if something abnormally retracts I worry cuz...well...I'm a reefer lol.

I absolutely understand. I just went a spree looking into SPS mesenterial filaments because I got some that actually show them during feeding. Hadn't run into that prior lol
