I packed in plenty of dirt. Then I carefully spooned out some of his old dirt, moving the top layer off first. I topped the new habitat with it. All the while, I was keeping him from coming completely out of his cage. SFB is a very calm specimen. I was easily able to pick it up and move it to the new cage. I left him in it for about an hour before feeding him. He has much more room now! And he had no trouble with the crickets I gave him.
This photo doesn't show how much space he has, but at least it is a new photo, right?!
