Duncan coral poop?

[Reef man 89]

Just noticed my Duncan coral is expelling long black strings. But the coral itself has 8 heads and all are doing it at the exact same time. So I thought many be they are pooping but I have not fed it in about 2 weeks so i don't think that's the problem. Any advice

Your description sounds like they are pooping. While you may no have direct fed in a couple of weeks, they will still be filter feeding.

I haven't heard of corals pooping... is this a thing? I suppose their mouth is their anus. I suppose I don't witness mine dispose of unwanted materials

Yes, corals and anemones excrete waste through their mouths. Only one way in and out!
