He maybe a foot or just a little over.
He's in a 20g encloser, identical hides. Warm side is 90 cool side is 79 humidity stays between 50-60. I measure them with acurite thermometers i got at walmart. I waited a week before i tried to handle him, but now i handle him 10minutes a day or every other day. I offer him food every 7 days
The size of the enclosure could be stressing him out. You may want to try moving him to a 10g tank or a small tub.
Is it male or female by the way? You said both in the first post.
