Oh, I totally understand that. I agree that the whole tank looks VERY natural, and it would be a shame to add tropical plants. However, this wasn't my point (and I think I did kind of explain it wrong). I was just using the back right of the tank as an example of the type of "outline". There seems to be a larger 3-set-root of wood there. And this is what I am trying to get at, not the whole tank, or the numerous smaller peices of wood. However, that is definately something I would like to try in a different tank (and I have been for a couple weeks in a 10g). For now, I was just getting at the larger "little-t" section of the back right of the tank, which is most visible in the 1st and 3rd pictures. I would try to highlight it in the picture, but I really don't feel comfortable doodling on his photography, regardless of the purpose. I think a similiar "little-t" peice of wood, half in, and half out of, the water would be perfet, as would a peice of wood with a "V"-type joint, so it could be hung from a center bracing, or whatever else, with little if any trouble.
And if my little idea is actually put into use, I will definately be PMing you about buying Mangroves. They aren't sold anywhere close to where I live, and Mangroves are definately the type of root system and effect that I would like to have, so thank you for telling me. I'm not sure this project will ever be used, because for now it's out of my budget, and I need to do much more research before I attempt it, but now I know where I can aquire what it would take to put into action.
I hope I'm able to articulate my ideas without it sounding jumbled and confused, or worse, completely ridiculous.
