I have two american green tree frogs, one male and one female that I got at the same time. Iv had the for a few months now and theyve always seemed to get along (Laying next to each other or practically on each other) but lately my female has been like jumping at him and not exactly biting him but with her mouth open. Before this happens they usually stare each other down and he'll like run to her and then shell jump at him. Im not sure if they're being aggressive or if they play?
