Very worried, my Goober will not eat

[Eridu Serpent]

He will not eat night crawlers, I have a tank of about a thousand earth worms and both frogs refuse to eat them.
Pickle will only eat them if they are in a pile, so she has one gulp then they slither off.
The humidity is a problem at the moment, I cannot get it that high as our atmosphere is very dry at the moment.
I will have to keep spraying every 30 mins.
At the moment the heat cable is off, as I said the thermostat controls it and it has not been on for ages.
It is warm enough without it on.

I tried to get him to eat by giving him a change of scenery, I put a tank outside in the sun for a while with water in it.
He just sat under the shade while Pickle swam around.

He´s always been a picky eater, lazy but he would pack away 50 king worms in a sitting...or as many crickets/miel worms etc.

What kind of lid do you have on the tank?

[Eridu Serpent]

It is a huge plastic storage container, so it has a solid lid that clips down.
I have never closed it, it is always 1/4 way open on hot days and slightly open on normal days.
I cut holes into it for the bulbs.
It also has an air hole in the middle.
