Rock anemone sleep?

Are they open during the daytime? This is pretty normal behavior for an anemone since they will extend out to receive light, but at night they will retract in for protection since there is no light.
 
I introduced 2 rock anemones yesterday. And i woke up and they are super shrinked. Like super tiny. Do they shrink when lights off? Is that normal?
Rock anemones take time to adjust in new water conditions so give some time to it. It will find its place where it want to live. Feed it once or twice a week. It's my personal experience

I just got them yesterday and they attacked to the rocks. Today woke up and they are extremelt shrinked. And im kinda worried my lights are on full intensity. Not sure whats going on. U can barely see it.

Do you have crabs or shrimps as they can pick them at night
