Shrimp and Clownfish Sharing?

[Riverspirit]

Hey all. I was just wondering if an anemone shrimp, can share an anemone with a black and white clownfish. I am thinking about getting a rock flower anemone, and have a 28 gallon NanoCube with a pedersons shrimp and the black and white clown. Mostly worried about territorial issues, as they will both "claim" the anemone for themselves.
