Hi! New to the board and I'm sure these questions are played out, but I need some help. I just purchased a 20 long with a secure lid, hide box, thermometer, water dish and astro turf for a new corn that I will buy soon. My questions are, can a heat pad that goes under the tank be kept on all the time? Anyone ever heard of these things catching fire? Lastly, do I need a strip light for the corn or is room light good enough? Please help, thanks, Anthony
