If I do this, I'm doing it right. It's not going to be a 50% job. It'll be good, even if it takes me a year to complete fully.
I'm definitely going to get advice about aquascaping if I go through with this, because I'm not incredibly creative and just logging in to MFK, I get inspired. Now, the only thing I would be worried about is the humidity, mold and fungi factor related to the warm enclosed 60-70 gallons of water...
Also on the land portion of the tank, would fake plants be adequate for some of the trees, or bigger plants? I could get a moss or something for the ground, and maybe some odd branches or pieces of decorative 'debris'.
Well, keep us posted on your progress
I'm not sure if you're in the right forum for aquascaping though. This is for monsters after all, maybe only a few with planted tanks and even less with paludariums.
