ug zim hasn't eaten in three weeks and won't even react to the food...he'll move away from it but won't strike or show intrest at all...his temperatures have been between 80 and 85 on the warm side, he's on aspin bedding and i've already checked him for mites and pests (finding none), he's still active at night and will crawl around the tank, the humidaty was a little high for a bit (about 65) but has gone down to about 50 now...he does have a female bunking with him but they have seperate hides and he chooses to bunk with her.... should i be worried or is it just because he's not hungry?
