My apologies, we don't get email notification for these types of messages. A wild caught Tokay is highly likely to be aggressive because they are accustomed to predators and weren't collected very gently to shipped to us. They find everything threatening and their defense to that is to be aggressive. A captive bred is less likely especially the more interaction they get, whether handling or hand feeding. I will say that even a 'tame' Tokay will bite, but a majority of the time it will be a bit of pressure and some spit depending on what the Tokay is trying to tell you (as in 'go away', 'stay away from eggs', 'I'm tired of being held', etc).
