As long as they're hiding enough moisture, heat and shelters, it will eventually feed and these guys just love to eat! It's best to keep temps in the low 80s during the day as most literature supports this but cool temps below might cause a lack of appetite. But it's also common that herps will go off feeding until they've settled into a new tank. At night it's good that temps drop slightly. I would just keep offering once a day, ideally at night when the frog comes out of the burrow. I wouldn't stress over it, you'd be surprised how long herps can go without or with little food. Only if it's a long time and there's weight loss would I be concerned
