Levels within a VIvarium

[clownonfire]

I'm building a new viv and have a question on dart frog behavior. Will they climb or crawl up to different levels? I would like to have a stream flowing down a incline with moss covering both sides and the slope. There would be different levels of flat areas with more moss and plants. How steep can the slope be?

Here's one I can actually answer! Some darts are often arboreal (think thumbnails), and some will prefer ground levels.

So basically, D. tinctorius, D. auratus, D. leucomelas, P. terribilis will thrive on land (even if they can climb), therefore more horizontal terrariums and thumbnails, or if you get out of darts, mantellas, will be happy climbing, so better for vertical terrariums.

When I contacted UE, they suggested slopes, but nothing steep, something they could basically walk up.
