OK got my first Beardie baby today. He or she is in a 15 gallon tank. I am using a Zilla 50 basking light. I will be purchasing UVB lamp tomorrow. My question is should I shut the basking light off at night. Will the dragon be OK without a source of heat at night or should I also buy a CHE to use at night. I am in NJ and right now we are in the middle of a cold spell.
