Congrats on your new Ceratophrys cranwelli. If a baby, the large tank will stress it, so its better to keep in critter keeper (only need substrate, water dish and silk plant) until it reaches 3 in. SVL.

Recommend get a ExoTerra Combo gauge or similar. It's important for baby health temp is 82F during day with few degree drop at night and humidity stays between 70-80%. More info on their needs can be found in here: Frog Forum - Pacman and Horned Frogs - Ceratophrys - Care and Breeding. As Mike mentioned, you can place the whole critter keeper inside the 10G since it's easier to control the parameters in the larger tank. Good luck !
