what about sleeping on the temp/humidity controls? (or the lip of the terrarium?) I'm assuming that the same would be true for this as well, right? also...is it a good sign that I can only find about 4 out of 6 frogs each day/night when I go looking for them? they are very good hiders and I've only been able to find all 6 of them (they are froglets) 1-2x since they were moved to their home.
