Need help with pacman frog

[Bombina Bob]

66 degrees is too low, the temps can go as high as 82. 70-75 should be a good nighttime temperature. Heat mats and light bulbs are your best options for heating your frog. heat mats should be placed on the side or bottom of the tank, the temperature should be monitored as well to avoid overheating. If your pacman frog is refusing food, try covering 3 sides of the enclosure, nobody likes living in a transparent house! Earthworms and nightcrawlers are by far the most nutritious thing you can feed your pacman.
