As far as substrate goes ABG mix seeded with microfauna over a drainage layer or false bottom is the gold standard. Regarding plants, live is best and pothos is a simple option. I wouldn’t recommend bamboo. If this is your first foray into dart frogs I’d recommend a different genus as a beginner such as phylobates or dendrobates. They are more forgiving than the thumbnails. All this being said either way a 12 by 12 is too small to accommodate either.
