My bad, take the rock with anemone attached. Again, the odds that when you put the anemone in the tank, could detach itself from the rock and start wondering and probably land on one of your most expensive coral SPS or chalice colony. I see those beautiful tanks with its corals thriving in brilliant colors. Many of those members secret they avoid putting there hands inside the tank and avoid moving stuff. I've had many anemones all types, and many clownfish, let nature take its course...my two cents.
