Found a grey tree frog in a house plant and I got him all set up in a tank. He seems to have settled a bit and is moving around now. We are just keeping him until spring and I was wondering if it would be okay if he just ate mealworms. I have read their main diet should be crickets but my mom doesn't want to deal with the chirping. He seems pretty fat and healthy, will this be okay? I will try and convince her if it would be really bad for the little guy. This is my first time caring for a frog.
