To add to this, I just cleaned his cage on Sunday and he was looking fine until I left for work 11 hours ago. He has been looking plump lately but I figured he was just eating a lot of crickets. Right now he looks like he is trying to swallow down something but is still having a hard time. His skin color is looking like a much paler shade of green than usual. I am using loose coconut fiber substrate in his cage. The temperate in the the cage is currently at 77 degrees but during the day it is in the lower 80's.
