Dear,
When they do not eat for longer than 2weeks that isn't a good sign.
When they shed they might not eat for a few days, but when not within two weeks an infection could be the reason.

And about temperature:
60-75 is too cold, definitely.

It should be at least 70 at night and in the 80s during the day. And not only under the spots.

So maybe that's why your Toad isn't eating. But since the other does, maybe a disease is the case.

Hope it's not for sure, just report back how long the toad is not eating...

Best wishes,
Oliver
