That sounds fine for a tomato frog, although you'd be much better off with live plants (which may require adding a light if you didn't have one). They really thrive in planted tanksI have a terrestrial set-up with a small water dish which I used to fill with water for my pacman to have a swim and not drown. I have some fake plants, and used to put moss over the eco-earth to keep humidity up. Also I was using a heatmat with a thermostat. Tbh I don't mind not handling. I didn't handle my pacman unless really necessary.
