I bought a young bp sunday, and the place that I bought my suplies told me that I should use an under tank heater, and have her cave placed on top of that, then to place a heating lamp on top the tank shinning down on top the cave, its a 75 watt red bulb, and her cave is the kind that she can bask on top of. It seems that she prefers to stay on the cool side of the tank, and just goes in the cave periodicly to warm up, I have yet to see her bask on top the cave, and I have not seen her even notice the water in the tank, which I keep fresh everyday. Does this sound like normal ? Im a little worried about her.

I am heading to work, so I will not be able to read responses till I get home tonight, thanks.

Should the cave bee on the cool side?
Should the water be on the warm side?
