Absolutely They should sway without hitting or brushing against anything , pretty Hardy gorg once it gets use to your system I have several of the eco gorg I had brought in a bunch with concept and I tried 9 of them all but 3 did very well and I still have them, the whips are a sensitive one I've tried two and no luck I thinks its a flow thing.
Most I find love high flow I'm over 100x flow rate and I trim mine quite a bit it grows fast
They arnt aggressive but don't appreciate being sting some of my Gorgs have pink star polyp growing on them they don't mind.
Should have polyps out all day long and bright not always at night
They also shed and do not appreciate algae growth on them
