My oldest tad (all four legs, 3/4 tail left) should be out of the water in a few days. He's a Pacific Chorus Frog, which mainly feeds on crickets. I know where to get super tiny pinhead crickets for the frogs, but I'm wondering what the best thing is to dust crickets and other foods with? I don't want something super expensive, but I want something good. I have a local vivarium store, a local petco, and a local petsmart. Thanks for any replies!
