Having it inside the tank is very dangerous as if it is moved it will ramp up the uth and create a unsafe hotspot for your snake.

Remove it asap.

Depending on the brand of tstat you have I would trust it first. What brand is it?
I am removing it right now. It's a hydrofarm thermostat. I am saving up for a better one.
