I have a corn that hatched on June 5th, and another that hatched a couple of weeks prior. When I purchased them, the seller advised me that both ate on June 15th. I fed the older one 2 pinkies yesterday but the younger one wouldnt eat, he lunged at it but seems very scared, he is not as active as the older one. Should I be worried, or just try to feed him again maybe this weekend. I dont want to have to force feed him.
