I have a new Condy Anemone in my 29 gal SW tank. After being there about a week, it captured a sand bug (a crustacean that is about 1.5 inches long and kind of football shaped). The anemone works on the sand bug for awhile and then releases it, and then takes it up and works on it some more. This cycle has been going on for 2 days, and I'm concerned that whatever guts may be left in the sandbug are rotting. I don't want it to poullute the tank, but I hesitate to take it away from the anemone. Any advice?
