Update if anyone is still interested. My anemone went for a little walk the other night since it never anchored itself in my tank. After its walk it buried its foot in the sand right next to a rock, I am assuming since all i can basically see is a little of the underside of the oral disk and barely any of its column. It chose a spot in the middle of the tank in the shade of like a little bridge/tunnel type thing I built, so i hope it'll start to reach out for some light soon. The position of it kind of sucks since its facing the right side of my tank but as long as its healthy and has its foot planted I am ok with this. Thanks everyone!
