Decorative BRB set up

[nimrodfiftyfour]

I think I have decided on getting a BRB. I have a few questions about the set up however. I have a spare 50 gallon aquarium to put it in, and I plan to seal the top to keep the humidity up. I've done 80 to 100 percent humidity in aquariums before, so I shouldn't have a problem with that. First of all, can I keep live plants with a brb, and what kinds. I'd specifically like some of the predator plant, ie fly traps. Also, I plan on making a waterfall decending from one end to the other of the tank, would that pose any danger to the snake. I plan on having a large pool on one end, maybe about 10 gallons of water, once again, good or bad idea? Also, and this is going to sound a little weird, could I keep fish in the tank with the snake? I was thinking either some killis or endlers, poss. mudskippers. I know husbandry on the fish, but would the snake attack them? Thanks for any help
