Is it alright to use a red light on Pacman Frogs? The cage in front of him houses a Leopard Gecko and he uses a red heat lamp, 75 watt, and some of the light does hit the frogs' cage. The light isn't on him but the light does light up his cage though. I added some more substrate to his cage, he hasn't burrowed down in it (normal, I suppose) and the temperature now in his cage is between 80-82 degrees F (26-27 degrees C)
