I have had my anemone for about nine months. It keeps moving. He can't seem to find a spot that he is happy. The other day I found him upside down in the bottom of the tank. I did get him to reattached and he ate tonight. He attached to a small piece of rock. We have a 70 gallon tank and are running 330 VHO lights. Where would be the ideal place to put him in the tank. Any suggestions.
