Anemones are very difficult, as has been said many times.
You can't "place" an anemone where you want it. They have a mind of their own. They sometimes stay in place, but often times not. That is especially true of Pink Tips.
The best thing you can do is leave it alone. If it dies, don't replace it. Anemones are far too little researched and understood. For instance, the Pink Tip is from the Caribbean. Clown fish are from the Pacific. There is a good chance clowns will never "host" it. Some species of damsels (same family as clowns) are also known to host anemones (I've seen Caribbean damsels in anemones while scuba diving). Again, though, it's far from a sure thing.
