I think what I'll probably try to do is get one of the infrared incandescent bulbs first. Those are supposed to put out heat, but the light going off and on as the thermostat keeps the temp at a steady level isn't supposed to affect the frogs at all from what I've been reading. That way it won't irritate them or mess up their sleep cycles. I'll try that today, and if that isn't working by tonight then I'll probably try putting that small space heater on the floor near the dresser that their tanks are sitting on. With the heater pad, they've been holding steady at 72, so I only need the temp to go up ten degrees or so. I think between the pads and the bulbs that it'll probably be okay, but I'm determined to get this resolved as fast as possible. If it doesn't work, the bathroom's not a bad idea for a temporary fix. I don't have the space for them to be in there forever, but it'll work in a pinch until I construct something more permanent in my room.
