Damsel and Clowns is it possible?

I have a jeweled Damsel and two occelaris clowns and they never cause each other any trouble. In fact the clowns are way more of an issue than the Damsel, they bite the crap out of me when I try to clean the tank!

I only kept this particular damsel because it was fully grown, very well mannered, and my wife loves it. I consider myself fairly lucky though.
 
I have 2 Damsels (yellowtail & domino) in a 30 gal tank with an Ocellaris Clowfish and have had no fighting what-so-ever but my domino damsel is a turd and eats everyone's food....I can't catch that sucker outta my tank for the life of me so I've just left him.
