Just a question on my Mexican Red Knee. I got him/her Oct 23rd(ish) and it's only eaten one cricket since I got it...

I have it in a deli container, a rectangle one maybe 3.5" x 5", holes for ventilation, a hide, and a small bottle cap for water. It's the largest T I've owned so far, and my other species eat consistently at least once every 4-5 days, so I'm starting to get a little nervous. At first I figured it was about to molt, which I still think it will soon, but it's not eating. I gave it a live cricket maybe 2 days after I got it, then have attempted since and even tried a prekilled cricket and it's just not interested. I tried a mealworm the other day, pretty sure the mealworm got away and burrowed in the substrate

Either way, just wondering if this is normal?
