How big is the enclosure? I have American toads and kept one successfully last year and she is still going strong right now. A ceramic heat emitter 60 W if the enclosure is big enough could heat the enclosure. Uth gets the enclosure around 2-7 degrees warmer. My WTF tank has one and that's where my info is on that. A ceramic heat emitter if placed well by observing how hot it makes the enclosure could work. No added light. But make sure it's placed far enough away that it hits the temp you want or it can bake the enclosure. I'm using a 100W for a 75 Gallon. Have not yet but I will tonight. It is in a hallway with little heat. Hope this helps
