Silver/blue Xenia doesn't spread wildly?

[zachfishman]

There's an area of our reef exhibit I'm looking to liven up (thread: http://www.reefcentral.com/forums/showthread.php?t=2247438)

Pulsating Xenia would be great, but I know it would be a nightmare in short order (polyps bailing out and colonies springing up everywhere). Instead I was recommended blue or silver Xenia, which supposedly doesn't spread crazily. Is this true? Big stalks of Xenia would look great in the barren area I'm looking to fill.

I have blue Xenia and its very slow grower in my tank but the pulsating Xenia I have grows like crazy and needs trimed back all the time.
