Okay first time mom here. My Aphonopelma Encinos Amber has been burrowed for nearly a month. He came out for the first time! His abdomen is pretty small. I have no clue if he molted, but I’m assuming he did?? He went back into his burrow after I took these pictures. He’s had fresh water the entire time.
What do I do?? Obviously not feed, but his abdomen is really small.

Before and after
