Unless I could find a 8x10xX" clear container, I don't think a pond would really work since I doubt my glass-adding abilities, lol. If I could figure that out, I would probably use it for its original plan as a betta tank. Might be nice with a pond though, hmm. Maybe with moss climbing out of the pond and up some branches, maybe a couple nice little alternatheras or ludwigias...hmm...
I don't know why, I'm just not feeling the terrarium thing. I know it could look good (actually one of my first thoughts for this tank), but it's just not appealing anymore.
