Duncan coral not fully open

[Yahdiel91]

Hello reefers!

Got this duncan 2 years ago with 3 heads, currently has about like 12 more in the process of growing.. The duncan has never had an issue and has always been open and fully extended.. Today he seems a bit down and not fully extended, every other coral seem fine.. Thought maybe they retracted cuz they normally do when a fish swims by them quickly but they normally open back up right after.. it was way more retracted than the pics ill be posting but its very slowly opening up.. Not sure what is up or if its just an off day for it.. Parameters seem fine, nothing seems to be bothering either..

Salinity: 35.2
Ph: 8
Ammonia: 0

I’m going through the same thing I keep testing and everything looks good, can’t figure out why.

Duncans can be moody at times, I wouldn’t worry until it’s been quite some time that they remain closed.

Since the post mine have opened up again.. i was told they tend to close up when growing new heads, mine were closed exactly 5 days.. Ever since I've noticed like 8 extra heads.. Give em sometime and yes they're also moody and close up for smallest of changes..
