New frog owner here. I got a chubby frog for my first frog since I heard that they're hardy, they're adorable, and the conditions of my room seemed convenient (Humid, kept at around 75 degrees, lots of natural light, and I dim the lights at a consistent time every night.)

My frog has buried himself in the coco fiber substrate, and hasn't come out since I got him. That was two days ago...

I knew that this species stays burrowed most of the time, but how do I feed him if he's always buried in the dirt? I always check at night since I know chubby frogs are nocturnal. I've tried misting the tank to see if the sound of water in the dish makes him come out, but no dice.

Should I be worried?? Is he stressed? The bottom of the tank is glass, so I can see that he's still breathing, but I don't want him to starve!
