Im sure everybody's experience is different. however, I have had my purple tip condy in my tank for about 2 years with a pair of gold stripe maroons in there. the maroons really take care of the anemone and in turn I have never seen the anemone do anything harmful. In fact, he hasnt moved from his spot for the last 2 years. maybe my condy is peaceful, I dunno, but I have never had a problem.
oh also, I have a sunburst anthias, flame angel, 2 bangai cards, dwarf lion, kole tang, scooter blenny, mandarin goby, 2 fire shrimps, coral banded shrimp, stars/crabs/snails and he has never tried to eat anything.
