It might take a few days or so for the polyps to come out. At night time the polyp extension should be a little better than the daylight, since they usually feed then.
But again, I wouldnt give it much thought, it was just added. Give it some time to get used to your tank

All of my birdsnest polyps retract at night. I have had it for about a month, and it is still very healthy, so i wouldnt worry about it!
