There is a section for Chubby frogs, but will answer your question. First a heat pad should never go under a tank of a burrowing frog. They go on the side. Next you have way to much substrate in the tank for a baby or even an adult. You only need enough so the frog can cover itself. Tomato frogs like temps in the mid and high 70°s.
Go ahead and answer these questions http://www.frogforum.net/pacman-frog...enclosure.html and repost your answers in a new thread in the Chubby frog section of the forum since this is thread hijacking.
