Thanks for the heat info. That's all I was looking for.
Unfortunately he had the monitor such a short period of time I did not get to see its condition. He paid no mind to my strong advice against getting a Nile, as all the experience he had under his belt was keeping a leopard gecko for 4 months. I don't feel comfortable going on what he says is healthy or not. He only had it for 2 weeks before he realized he was in over his head, and was also scared since he had a child in the house.
