Aussie Elegance Coral closing up these past few days

[Newjack2005]

I'm currently running 3 radion gen 2's on a 220 gallon tank and my Aussie elegance coral is placed in the sand bed was fine and beautiful for a week and now is closing up. The water test came back fine my light intensitiy is at 75% should i maybe turn it down or is it the nature of the beast with this coral.

I have had my Aussie elegance for over a year now. Some days it's open huge and some days not so much. The difference in size is close to 50%. When fully open it's about basketball sized.

I can't figure out why it has smaller days. I have a bunch of other LPS and the rest seem to be doing fine.

I do know that if I feed Coral Frenzy, or one of my other coral foods, then the following day it is always opened up huge again.

I have some clowns that host in it on and off throughout the day. I have a pink shrimp goby and harlequin shrimp that live underneath it.

As long as your params are fine I wouldn't worry too much as they can close up for days at a time for no apparent reason.
