Got a new green tree python about 3 weeks ago (1.5yr old). Previous owner said he had eaten 2 days before he handed him over to me.

He hasn't eaten once. Live or frozen, he'll take some warning strikes and then slink back to his perch, totally uninterested. I chalked it up to the stress of being in a new tank.

It's been 2 weeks since I got him, a total of 3 weeks since eating. To not stress him out, I try every 3-4 days to feed, still nothing. I know these guys are a little hard to take care for, but this isn't my first, and I've never had trouble feeding any of my snakes like this before.

All temperatures and humidity are well taken care of, can anyone offer any advise?

If you need pictures (which I doubt) I can submit them. Thanks in advance.
