Haha no, just took it from a song. Having the flowerpot (or Goniopora) coral isn't a bad thing. While they are extremely difficult to keep alive long term, i'm more worried about your damsels hosting it because that will lessen their life span tremendously. While it isn't your fault, you will have to take measures to ensure the survival of your coral either by taking out those damsels that are hosting, or taking the flowerpot coral back.
Hosting is hit or miss, and there really isn't a whole lot you can do as a hobbiest to get clowns (or damsels) to host your anemone. As you've found, they really host anything, corals, anemones, power heads, heaters, they really don't care. Just a place they feel safe.
