Last night Gandalf passed a big poop, the biggest he has ever passed. I believe that was the remains of the maggot. I figured he would be hungry after having finally passed that. Tried giving him pinheads, he ate 3! he is completely gray now. Ill post photos later on. Thanks for the help guys.

Edit: oh and I inspected some of his poop. The big one which I believe was the maggot did have some maggot like skin in it. And his smaller poops are not to wet and not too dry. Looks a lot like soil. Breaks apart like it as well. The rest of his poop was in the water bowl so I wasnt able to test it.
