Did not get the Tupperware container thing until saw pics; cool idea. Why the fan? If it's efficient at moving air you will have issues trying to control heat and humidity if room ambient air is cold and dry. Live plants always look nicer than fake ones but an African Bullfrog can be rough on them.

Also, make sure the plant leaves are not toxic. Already had Stilgar jump once for food and landed on top of an Exo-terra fake plant with foam like leaves. He knocked it over and ended snipping a leaf tip off and swallowing it. Had trouble passing it too. If your African Bullfrog accidentally eats a toxic leave it could be bad.
