Hi all. Been kinda concerned about temps lately. Her warm side is ok, it's the cool side that I am worried about. The tank at night gets to a cool 65 degrees. Daytime is mid 70's. Is the night time temp too cool? I'm just worried that it would interfere with her digestion. I've just read that it needs to be in the low 70's at night. Am I worrying about nothing. Please let me know. Thanks!
