Yeah, that is a sweet tank and I saw it a while back too, possibly at Aquatic Gardeners or Aqua botanics as I have never checked out ADG prior to tonite. Some spendy homes there in Houston!
The first time I saw this discus tank, I thought the anubias would cover or rather swallow the wood. Peter Hiscock recommends black thread to tie plants to bog wood. It looks just like a root and in no time the roots take over.
