built off the center structure and just make it one big island with sand as substrate. use anubias, jf, hygros, mosses, blyxa, and maybe some hydrocotyle
Yes, that is pretty much my thoughts here as well. I re did it a little bit if you can see the difference. I'm going with a Sand foreground most likely , at least where it V's in the Center area. Then thinking Amazonia etc. Background etc..
