Does anyone have tube worms growing out of their tonga branch?  There probably aren't many bristle worms in there either.  I probably wouldn't want to use 100% Tonga branch rock in my tank.  I tried cutting a Tonga branch with my jigsaw once.  Thought I was going to break the blade. 
 
As a note, the Fiji base rock at J&L right now is man-made.
