I just got a new tank from petco this last couple weeks. It came with a normal light and a purple light. during the day i have the normal light on and slithers stays under the woodchips and in her rock hideout all day. but almost as soon as its off and the purple lamp is on she's out and exploring. Often all throughout the night.

So i guess my question is..is the day light too hot? Or the nightlight too cold? Is she hiding from the day lamp and coming out when its cooler or is she getting too cold and moving around seeking warmth?

This tank was a starter snake kit and the lamps came with it.
