I finally got my temperature gun and a new thermometer and I double checked the temperatures in the terrarium of my remaining snake. He's not doing too bad, but he's not eating nearly as much as he did at the same time last year. I'm thinking it's a temperature issue, because I switched its tank a few months back and the new one is 2 inches taller, so the light is farther from the bottom.

After double checking, it looks like the previous thermometer I had in the basking area might have given me a reading that was too high, so I'll put more substrate there to bring that area closer to the light.

The odd thing is that my snake no longer hangs out in the basking area. He prefers the cooler side, where the temperature is around 20C. I would have thought it would prefer to hang out at the other end, where the air temp may be too low but is nonetheless several degrees higher and where the surface temp is 32C (unless my temp gun is faulty). It cruises around its terrarium every-now-and-then, but it never ever stays there anymore (that I know of).

He doesn't show too many signs of looking for a hibernaculum, but maybe I'm just not there to see them. ' will see what happens when I raise the substrate.

At least, other than the fact that it eats less then before (but it still eats, thankfully!), it seems ok.
