So today I needed help moving my tank around so I call my brother over. He's handled my BP before and has never been bit. He pulls my snake out, supports correctly, is super calm and the snake IS relaxed - no tension, tongue flicking, etc. My snake was fed 3 days ago, so he shouldn't be nippy. Sure enough, my snake is roaming on my brothers arm, faces his hand and slowly bites his hand, then tightens its body. My brother knew what to look for and didn't see it coming, and this isn't the first time my snake has done this (its bit me like this a few times). To get it to release we run its head under cold water and put it back into its tank. THEN - this has never happened before - the snake starts dunking its own head in its water bowl for about 5 minutes before it roams its tank. Does anyone know what that is about???
