This one is also very good:
Aquascaping ideas and design threads (including links to AGA and others)
Aquascaping is a bit of a sore point with me. I love the beautiful setups that are dominant in freshwater these days but feel they are sometimes too contrived, too poorly reflective of natural habitats. But thats just me.
I also almost hesitate to encourage you marine guys to look at these as it might dampen your otherwise wonderful creativity with design and use of macros. Still, great thread.
