I got an Ornate Horned Frog on Sunday (five days ago), and he hasn't eaten since. He is about the size of a quarter, has sphagnum moss as the bedding, an under the tank heater, and I have partially covered the top with plastic to increase the humidity. I have tried offering him mealworms and crickets, but he has eaten neither. Is there something I should be doing differently? I'm concerned because he hasn't eaten for almost a week and is so young. Should I change something I am doing? Thank you!
