OK so I'm a college student and I got my first sling over the summer. It's an E campastratus. Cute little guy. I just came home from college and he is looking super stressed out. When I got him he had a black spot on his rear which has slowly gotten larger and it's demeanor has changed significantly all its done was sit in its hole which I hear is normal for these T's. However I just did some enclosure cleaning and when I got him out he's just sitting in what looks like death curl and not moving. It's not just a stress curl I can tell that much I'm worried about it. Also does anyone have any recommendations on food for this little guy? The pet store that I was getting crickets from for him closed down and I've been struggling to get food for him (it just ate 3 days ago so I know this curl is not a result of hunger).
