Varro has been spending almost all his time on the cool side of his 20g long tank. The temps are 89-92 on the hot side, 80-84 on the cool side(this is in the hides with a temp gun that has a laser). He has a small UTH on the cool side, and a red heat bulb on the hot side. It is a screen top, but it is covered in Plexiglass except for a hole for the light and the humidity is always around 60%. He just had his first successful shed with me, and is eating fine, I'm just worried that he's not going back and forth at all. His hides are exactly the same on both sides down to the direction they face (towards the back of the tank). Any ideas?
