Ahhh... this debate won't end in my mind until I add water. LOL
1077, I love your idea. I initially had a visual image of a Kaudern Cardinal biotope, which would naturally be wooded and loaded with different seaweeds, and just a scattering of live rock. This is what led to my idea of a non-photosynthetic reef, which will require great research on my part to pull off, and with research and inexperience comes risk and $$$$.
On the freshwater side, I have some very nice driftwood pieces and beautiful silk leaf vines that are just going to waste. These would make a great backdrop to a live plant system. Live plants would also be a research project for me, because it has been nearly 10 years since my last live plant FW systems. The brain is a little rusty!
I could also move my 54 reef into the 90 and make the 54 a new setup.
Kymmie- I have no experience with Sea Dragons. I have also seen them at public aquariums, but this is about the extent of it.
