I have been wondering this as well. I've been working with acrylics and so I thought that, perhaps I could make a, with of course a screen cage for my cham, and strips of acrylic below so that i could have 1 a plant, my ficus, and 2 a below reptisun 5.0/heat source for my turtles, which would be seperated by a dark and thick acrylic(or something) covering the light source and screen below it so that the heat/vitamins could hit them and the mists from above wont hit the lights below. it seems pretty complicated but my main question. is will they indeed be to stressed out? my thought, because my cham never leaves the top of his tree house basking area except for sleep is that he wont ever see them and so wont be disturbed by them down below a potted plant and some structures for below lighting and basking. as far as smell, i have 2 fluval u4 filters and know how to keep a clean tank as ive done it most of my life, im 40 now
