So last night my cham ate all his food but one cricket witch I ended up leaving in there planing to clean it out in the morning but before I gat a chance to get to it he ate it. So my question is, can he eat dead crickets if they die in his the food dish or can he get sick.
No, he should be fed live, fresh prey. When they are dead they start to lose their nutritional value. It would not kill him if he ate one, but it is not something you want to do on a daily basis. How many crickets are you feeding a day??
