Is this Duncan poop or maybe something else? Released this about 20 hours ago ( first photo) and hasn’t been out since. (2nd photo) Can they take awhile after expelling like this? Thx for input
I see that a lot on other corals - not just duncans. Usually after I've fed Reef Roids, plankton or other coral supplements. It usually disappears in short order.
I believe it is a defense mechanism when something is agitating it or stressed. I’ve seen shrimp pull mouths open and corals digest slime to discourage any further aggravation.
