Urgent help needed green tree frog

[elly]

It looks like the frog's rubbing off some skin against whatever container it's in. I'd check inside edges for sharpness or try to make sure there's a place to hide so the frog feels safer. Sometimes frogs just do that though. If any of the cuts look infected, you can use bactine or antibiotic ointment but you need to make sure whatever you use does not have any painkillers in it.
