first off, My name is jeremy and my family is the proud new owners of 2 baby sullys. we have had them for a couple of months now, and just upgraded them to a 20gal aquarium. we have a basking light and a heating element on one end of the habitat. the "cool" end of the habitat stays right around 80 degrees, and the basking end stays right at 98 degrees. they stay under the basking lamp all the time, except to eat and take a quick dip in their water bowl. is the cool side of the aquarium too cool? also, it is quite difficult to maintain decent humidity levels by just soaking the substrate. i am afraid a humidifier will lower the temps even more(ultrasonic) any imput would be greatly appreciated!!
