I've put maybe ten pinhead crickets in my little guy's tank (most of which fell in the water after a while) and he won't even bother with them. He just sits there. He's a Pacific Chorus Frog and I made him a natural habitat with two pieces of driftwood, lots of moss, and lots of plants for him to hide in. I'm really worried because I want him to be healthy and grow. When I kept these guys when I was really young I would put them in a container with water and some dirt and they would attack the crickets when I put them in. Do you think that there's something wrong, or can he just not find them? What can I do to make him eat?
