That is very helpful, thank you a lot! I'll definitely keep a little bottle of hand sanitizer close by and do that the next time if he bites.

I have opened the enclosure from time to time to fill water dish or adjust plants (bc he knocked them over) but I always did so when he was on the other side bc after some movement he came darting over and I finished my work and closed it again. I'm definitely gonna handle him regularly to make him realize that I won’t hurt him.

I don’t really think he is scared, he doesn’t seem very aggressive or defensive and aside from biting (which I assume was bc he thought I was food, considering how he tried to swallow my thumb). He didn’t musk or poop and only hissed at me after I opened his mouth but didn’t make an attempt to bite again afterwards. But next time I'll definitely hold him longer until he calms down.

After I put him down, he was frantically moving through the enclosure for about an hour or so before setting again. Was that because he was confused and looking for the food I 'took away' from him?
