So in my room I have 4 of my snakes housed in their tanks in there, and my gecko is also housed in my room. At night, I keep the A/C on 80F at the lowest, but I usually keep it at 83F now. My sister puts it below 80F when I sleep, and today when I woke up (female BP's tank is next to my bed) the temps read 73F. I rushed over to the A/C meter (don't know what else to call it) and it was at 75F. I keep telling my sister she's going to eventually get my snakes sick and if she does she's paying for the vet bills even if she gets broke. Do you think after a while of having the A/C that low that it will eventually get my herps sick (RI)?
