yep for sure I know its plan, chicanery, deceit is the duncans way
of all possible shape-shifting, unnecessarily morphing mess with your head in spite of perfect conditions LPS, these take the cake. Not anything can be surmised when a Duncan closes up for a month, much less shorter. they literally do this at times across most reef tanks, in odd intervals, and ive never known why just that its their way to cause concern while being fine!
to know if a Duncan is mad or dying, I assess the other corals
