Hello, I bought this Hawaiian Sand Anemone 2 weeks ago. It is currently on the sand right now. It has been there for pretty much the whole two weeks. It was pure white when I bought it and it still is really white. During the day when the light is on it stays still, but at night the tentacle (i dunno what they are called) things move around and sway. Not sure why. I can't see the mouth most of the time and when I try and put food on it, it doesn't close up and eat it. Should I worry yet? thanks :deadhorse:
