blue cloves

Has anyone had experience with corals fighting off smothering by "blue clove polyps," i.e. Sarcothelia sp. corals? Or things that are not really prone to being overtaken by this particular coral? I want to put some in a jar with some light and let them go wild. But it'd be nice to have something...

I'm looking for some Blue Sympodium either bigger colonies or small mini colonies on live rock would be desirable but let me know what you have, how much and send a couple pics, Thanks!
