I will get some Pedialyte and do that. He is near a window, so he gets a seasonal day/night cycle with some light reflecting into his off my other critters lights. Should I get a light just for him?

I have the room set up warm and positioned to keep an ambient temp high, with the tank design it keeps the temps where they are at. I just picked up a heat cabe to raise the temp, I will put it in tomorrow.
