Be careful re the temp for the frog. I'm not totally an expert here but from having turtles, I think it may be similar re their metabolism. That is, if you keep it in an 'in-between' temp, it can't either prepare for hibernation nor thrive. PIck one. Since you're keeping it inside, I'd not lower the temp less than 60 F, though again, I'm not sure the 'trigger' point for frogs. For my painted turtles, it was 70. Lower than that and they wouldn't eat well. Just a thought.
