My 2013 jungle carpet still has not eaten yet and it has been about 3 weeks since I got him. I am going to try tonight as it has been a week since last feed. Is this normal? He still hides in his cave till about 2 or 3 in the morning. Also, I was wondering if my tank is too big for the guy as he is only about 18 inches. Do you guys have any suggestions for the tank or does it look alright?
