I can't tell why my sweet new little big eyed tree frog won't eat. I got her Saturday at a Reptile expo from a gentleman who said she'd eat crickets, but not a single cricket has been eaten. She's tiny, I call her Pixie, and I don't want her to die!! I've owned fire bellies and White's tree frogs before, but never the tree frogs from Tanzanaia, which she is! What can I do????
