is this normal bubble tip anemone behavior?

Mine shrinks completely at night, and by the time I wake up it is inflated. Since I am also new to the BTA world, I thought something was wrong and did a bunch of research. What I could tell is that they could be either expelling waste, or refreshing the water inside them. As people above have said, it appears to be normal behaviour.
