I'm getting my first ball python this week (not a baby) and I'm in the process of setting up my 40-gallon terrarium. I have my heat mat and thermostat with it of course but I also have a light fixture to use a couple bulbs. Are BPs bothered by those red or blue lights at Petsmart? I'd like to have them as a second heat source on a light dimmer I have and also because they look nice lol. What watt should I use and do I put the lamp fixture on the hot side with the heat matt?
