I'd be weary about the placement of that xenia. Once it gets out of control and covers your LR, it'll be a btch to get it off :S

Maybe have a separate piece of LR and give the xenia it's own island.

Yeah it will climb upwards, and spread out as it goes.

If you put it on the very top, it shouldn't spread downwards (mine doesn't) and it is a nice "cap" for your rock IMO, swaying gently in the current.

ya i was thinking about moving it actually, we'll see if there are any interesting frags @ golds today, then while i'm digging around in there anyways, i'll move it,
