iv wanted a leo for awhile now and iv head so many different things about how to heat the cage,i have a 33 gallon tank and i would really like to use an under the tank heat mat anf i want to use astroturf but im not sure if it will get to hot. I also want to have some source of light in there during the day so can i just use a normal 60 watt light bulb? and is astroturf ok to use?
