Hello all, we bought a BP 3 weeks ago. He's about 30" long, we have him in a 20 gal tank with a climbing branch, heating rock, Zoo Med Repti Bark bedding and a bowl of water changed every other day. Its our 1st pet snake, all we know is what the petstore employee told us and what we've read here/google. We handle him as recommended, about an hour daily except after feeding, then we wait 2-3 days. Its been 4 days today hes been snapping at us when we try to handle him, today he snapped at me when I passed by the tank, he makes a hissing sound before he snaps and when we change his water. We contacted the petstore and were told he might still be hungry so we gave him another mouse (he ate 2 that day) and that didn't solve the problem. Our main worry is his aggressive behavior gets worst or he bites our 7 year old son and he no longer wants it as his pet.
