Hey Mallick
I would do like the frogguys do, when setting up a viv. The only thing is to make sure the branches are the rigth size and type for the species og uroplatus you tend to keep.
also, I would not do any waterfalls as the bacteria would be spawning from a place lige this. (Im sure it can be done, but I dont know how, so wouldent advice it unless you are confident enough to give it a shot, could be nice).
I would check out blackjungle.com for inspiration, also I know that the frogmen from holland and germany are hardcore in setting up their vivs. (looks insain).
Other than that unfortunatly I can't help you out, hope it turns out nice. I got high expertations from you, so make me proud

hehe
And Mallick last words, take alot of photos of the process
Cheers
