So I picked up my first morph today. He's an '09 male pastel weighing around 850 grams (haven't weighed him yet myself though). Anyway, transporting him home tonight which is a 2 hour drive. I have him in his tank, no bowls or anything, with some handwarmers under a towel and a big plastic hide that he is in. I'm worried about the temp. Should I add any other heat packs or will it be ok for 2 hours? Temp is resting at about 75 degrees in the tank currently.
