I was away for about 4 days. When I got back the tank looked great except for one thing. My anemone was lost. I looked everywhere in the tank but could not find it. I thought maybe it died and the hermits got it or something. When I checked the skimmer later in the evening I spotted the anemone in the sump. Check out this pic. I took last week. Amazingly, somehow this thing squeezed through the cracks in the strainer!! I put it back in the main tank, and it seems to be doing ok. How can I prevent this?? Maybe a foam cover or something over the strainer? I am still amazed how that thing squeezed through that small opening!
