pixiefan- no way a round it unfortunately she will need to suck it up, put some plastic plants/hide of sorts that you can get under very hot water every day and cover all sides of the tank. i know you said it is zero traffic, but when everything covered a frog can't see the actual room and space around it, it makes them feel safer.
