Night time temperature

[Teguzilla]

I was just curious and wanted to know what's the lowest safest temperature you can keep a tegu at night. Our house usually cools off quite a lot at night but rarely goes below 65. Is that fine as long as it doesn't go lower than that?

I personally see no problem with that

His hide in the 70s during active season and 60s during brumation is what to aim for. If too cool, he'll burrow closer to the heat.
