Some anemones like to move a lot. I have 5 anemones in one of my tanks. 4 of them have found their spots and have not moved in months. My
rose bta will stay in one place for a couple days or weeks and then move again. Some times my rose goes upside down too, and I can't get food to her. Then she will come back around again and I will feed her. They want to just find the right combo of light and flow. As long as it is eating and looks happy I wouldn't worry
JMO though
