I put the black plastic hides in tonight and I got a small CHE to try to raise the ambient temps in the tank a few degrees. I'm curious to see if that changes his behavior any. I am not sure if it will help or not but I moved some things around in the tank so his water dish is directly under the CHE. My thoughts were that might help it from drying the tank out too much too quick. Im trying one of the dimmers on the CHE for now instead of a thermostat.
