Hi Cinnanon Pearl, the setup you have looks great for an adult horned frog. One suggestion I would make is go to a pet shop and choose an aquarium background of your choice and cover the three sides (back, left and right side) of the tank with it. This will ensure the frog feel nice and secure. Also, you would have gotten many more responses already if you posted this on the forum section specific to horned frogs. I would recommend you to get a digital thermo/hydrometer combo (I have one made by exoterra and it works very well) so you can better monitor the temperature and humidity.
