I started this on a 55g baby two nights ago and he still refuses to go into the hide! All over the tub including on top of the hide...but just won't go in. Once I set him in the hide and he hung out for about 10 seconds and then was back out again.

Gradient is 83-->76 air temperature with a 90 degree warm spot under his hide. I'm committed to just "leaving him alone" and assuming he'll eventually figure things out and go into the hide when he needs to...but he seems far more interested in trying to escape the tub than to settle down in his hide. I'm actually a little worried he'll get too cold if he continues to refuse to go into the hide.
