Needs more substrate, a lot more substrate, and dried substrate. The rule of thumb for terrestrials is 1.5x their leg span. So if your girl is 3 inches, 3 x 1.5 = 4.5" which means there shouldn't be more than 4.5" of height. This is because terrestrial Ts, especially fat ones like this girl, can fall and burst their abdomen. That added height with this hard rocks? Not a good combo. As for the dry substrate, if you got it out of a bag or had to soak a coco-fiber brick, you can roast it in the oven for a few minutes to get the water to evaporate.
