I got my Pacman frog and he or she is so cute. I named him Petrie but I am having trouble getting him to eat from tongs. He will not eat earthworms but will eat only a few crickets a day. I feed him in the evening the first night he would actively hunt the crickets. But after that he would just sit there until one came to him. I am dusting the crickets in calcium and vitamins. should I just wait and try the tongs again or just give up on them?
