I have an American green tree frog who just recently started to call, and has become quite healthy after a pretty bad illness. I also just got him de-wormed and was wondering if someone could help with something he's been doing since. He sits on the bottom of his tank and cunvulses his belly like he's throwing up, and does it for a few minutes and stops. Only late at night and he seems to go back to normal after. Any idea what he's doing?
