here is a pic of my viv so you can tell me if ok, size, furniture etc.I also have a apple tree branch to add when dry.size of viv-L-3ft W-1.5ft H-1.5ft.the snake is double over in the log at the back and still refuses to come out more than a few inches to get onto the heat pad.I am a little worried but not overly yet.Brian
If the snake is only about the same length as the viv, he may possibly be a bit insecure. See if you can get some other bits to fill it out a bit. Fake plants, or real are good.
He may also still be in a bit of a 'corn snake huff' from being left out, then moved. He'll chill and start appearing more often soon I'd imagine.
