What is a false bottom set up? And with the pothos, would it be better to have them in a pot and then bury that in the substrate or just plant directly in. Also, what sort of lighting and heating do I need that will benefit the frogs and the plants? As far as the set up, I read you could do water holes with container, half and half with glass or sloping. How would I slope the substrate to gradually descend into water without it soaking and stagnating the substrate? And how deep do the water need to be? I've read that they like it shallow enough to float while being able to touch bottom and that they like deep water for diving.
