Ok so I have a Haitian anemone in my tank. I added a couple of clowns a couple of weeks ago. I knew the anemone probably won't take to the clowns but last night I turned off the lights and went to bed, came down this morning and only 1 clown left. No sign of any remains anywhere, is it possible the anemone ate him? Do I need to get rid of him if I want clowns?
