I am so frustrated! Not having a lot of luck with zoas so thought I would try a rock flower anemone garden. Bought three last week and one didn't make it. Put the other two in my 72 gallon tank and all has been well. Cleaned the tank and changed the socks this morning everything fine. Checked at dinner time and one anemone is gone! My largest fish is orange shoulder tang and he is king of the tank. Anyone ever had this happen? Any idea what would eat a rock flower anemone?
