GpBp, if she avoided the heat mat, she is probably ok. Does she seem to have discoloration on her? Like a burn?
Regardless, you have to check temps and probes daily. Not trying to be mean, but Roe is relying on you.
How did you secure the probe? What kind of tank again?
Secondly, ambient is too low as is the cool side.
I get confused between all the threads and all the new BCI keepers. I thought we had gone through this. If so, excuse me here, if not, this is important.
BCI's want:
86-90F hot side/hot spot
79-82F ambient temps
79-81F cool spot.
Or there about.
Take a deep breath. Remember, panicking leads to rash and often poor decisions.
Remember the basics first, always.
1. Temps
2. Humidity
3. Cleanliness
If these basic husbandry items are met, you should have a happy and healthy snake for a long time.
This really explains, more than anything, why Roe likely hasn't eaten again. Also, she might not be getting enough heat (and she's avoiding the really hot area) to process food and pass waste.
Please update when possible.
Hope everything is ok.
