Good pick, I will go with Rhaphidophora pachyphylla, seems close enough. FYI I'm gearing up to do a proper vivarium finally.. I picked up some "Great Stuff" foam spray, some 100% black silicone, some peat moss/eco earth, some baskets for the plants. I've been playing around with the foam to get the hang of using it. I plan on inserting the baskets in to the foam to have a "plant wall", oh I also picked up some pvc pipe and egg crate so I can do a false bottom.

I actually had some nice wood pieces in the basement.. pics to come, I have a "cool" idea. =)
