Candy cane coral won't open! Help?

[Nanobros]

I just purchased my candy cane coral 2 days ago. He still haven't opened a bit. I'm not sure what to do. My calcium is a bit low but I am adding Kent Nano Reef to boost all my stuff up. I placed him in the sand bed.

I own a 14 gallon Biocube. Been in the hobbie for less than a year.

He still looks puffy, I say you are good for now. When it goes downhill you will see the flesh recede toward the head and you will see it shrink to the point where you can see the skeleton ridges through the top.

Check it out during the middle of the night, I only rarely see mine trying to feed during the day.
