If I'm going for L. Williamsi, this is now a moot point... Thank god xDYou wouldn't need to use live bamboo. Most people buy large stalks of it, cut it to size, and stick it in the tank. There are some species that stay relatively small and would be manageable with routine pruning such as Bambusa multiplex 'Tiny Fern' (~90cm), Pleioblastus distichus (~60cm), Pleioblastus distichus 'Mini' (~30cm), Sasa veitchii 'Minor' (~60cm), and Pleioblastus argenteostriatus (~90cm). How well these would do in vivaria, I do not entirely know. Most bamboo species don't like vivarium conditions, however some seem to do well. As you mentioned, these would be more for aesthetics than function. The biggest issue you'll come across for live bamboo would be lighting. You probably wouldn't want to look at the tank because it would be too bright haha.
I may have found a solution to this. Not the most aesthetic (unless I cover it with some sort of tape on the outside), but proved to work well in the store: A thick layer of that blue filtration thingie at the bottom, a double layer of white filtration sheets (I'm sorry, I can't remember the name of those in English, but they're basically the same thing I have in the upper levels of my tank's external pump) with the pump built into it in a back corner, and a layer of peat covering the white stuff. Their waterfall has been going on for two years with no clogging!As I mentioned in a previous reply, this will most likely result in a clogged pump fairly quickly. It works in theory, but as the smallest substrate particles make their way into the false bottom, it's going to build up and clog the pump. Same thing is going to happen with plant roots. Once the plants have grown in, accessing this pump is going to be a pain in the a**. Having a pump in a reservior of clean water out side the tank, and pumping it in is going to be far easier. Then just install a drain or siphon it out of the false bottom when it gets too high (you want a decent gap between the water level and the bottom of the soil to prevent wicking and swampy conditions).

I'm just afraid of what I can put into the tank considering it's going to be rained on fairly often... I'll figure that one out.Basking lights (assuming you're using halogen) will create a drier area without you having to adjust for it. You may have to make sure the tank doesn't get too dry from the light if anything, though that depends on the wattage.

I had no idea, once filled to acceptable levels, I should be fine for years with just one refill container for evaporation!If you distilled/RO water, you won't get the stains on the glass.
Replaced that with peat, been told it'd work just fine, but that means I'm going to be growing mostly moss on the ground.What's in the Exo-Terra rainforest substrate? Since you have access to Xaxim, you can probably get it as loose/shredded. If you can, I'd look into ABG mix (I'll post the mix below). It's designed to prevent compaction of the mix and have great drainage, while still holding moisture for plants. It'll eventually compact through decomposition, but it won't be for a few years. The main thing you want to prevent is compaction leading to anaerobic conditions (like having too deep a substrate in aquaria).
I'd also look into an inert media like Turface (calcine clay fired at a high temp). It takes decades to break down, and won't compact.
ABG Mix:
-1 part milled peat
-1 part milled sphagnum moss
-1 part fine charcoal
-2 parts fine tree fern fiber/Xaxim
-2 parts fine orchid bark
Good for me!I've got way too much spare time currently, I don't mind typing out really long answers!

Yep, figured Tanzania would be a pain, I'll stick to mimicing rainforests from across the world xDSpeaking from experience, Tanzanian plants are fairly hard to find. There are some commercialized species (Saintpaulia sp., Impatiens walleriana, &c.), maybe a few orchids and Rhipsalis baccifera that are going to be fairly easy to find, the rest is going to be very hard to find.
Being found almost exclusively on Pandanus sp., the bromeliads you mentioned would be a good stand in.
Yeah, I heard you don't necessarily need to incubate either, they just breed lol.Yeah that should work. They breed fairly easily, so you could even start with a pair or trio, and have more than enough in a year or 2.
Could even start a business on those critters, I don't see them often here.
