Temberature fluctations, concerned too cold? (Ichthyosaura alpestris)

[paraselenic]

Hi everyone! This is my first *official* post.

I have a brand new pair of alpine newts set up in my basement. My basement is generally cool, but sometimes downright cold. I've seen many posts from folks on keeping newts cool, but mostly that's below 70 degrees-- I've had nights get down to 50 in my basement. I'm wondering if I should keep a small aquarium heater handy for drops in temp that low? What is the optimal comfy temp for alpines?

My main goal is to NOT have surviving newts, but happily thriving ones, so their comfort in a good home is my main goal.... while they might be able to tolerate lower temps, how low is too low?

Thanks everyone!

That seems fine in my opinion. I'm jealous of those temps. My basement is consistently 63-67 no matter the time of year for some reason. Reading the care page the temps that are best are 50-65F.

Hi Para,
I allow my colony of alpines to get very cold in the winter - as low as 43F, and they don't skip a beat. They continue to eat and are active, and the males begin tail fanning and pestering the females at these temperatures. The plants don't like it, but the newts sure do! Adults, larvae, and recent metamorphs are all exposed to these temps and they have all done just fine for me. Keep in mind that this species inhabits alpine lakes in the wild and are probably living in near freezing water while in their native habitat. I think the danger of too hot is more a concern than too cold.

Best of luck with them! They are gorgeous little newts and have funny personalities.
