Hi,
One handy tip is that normally the wrinkles they talk about with dehydration run parallel to the length of the snake whereas the wrinkles that show up with shedding tend to run in the direction of top to bottom at the "bends".
If he is still feeling nervous then the move to another tank might have unsettled him a bit for sure. Maybe give him another week to settle in with minimal handling and disturbance?
I would try and have a look at the colour of his belly (i.e. does it have a pink tinge?) and if it looks like he may be shedding even bump the humidity up to around 70%. Also have a look at his eyes to see if they are going cloudy.
But if it has any strange discolouration ( red or brown ) or damage to the scales try and get a picture to show just to rule out any problems.
Most of mine do not eat when in shed and seem a little more "scared" so I tend to just let them be till the shed is finished. But then others have snakes who continue to eat fine so it's all down to the individual wriggler.
Hopefully some of those ideas help.![]()
