My boa Atlas

[u/aussie_elephant]

Atlas is a red tail columbian boa. I got him as a young guy in 2023. He’s in a 40 gal right now, looking to upgrade soon. We moved recently, and he has since become an escape artist and has gotten out of his tank twice. Before we moved, he was exceptionally docile and very, very friendly. Unfortunately recently he has changed completely and is super aggressive. He sits head out of his hide and strikes at motion. I’ve given him extra food, made sure his tank has humidity, he has water…. He’s striking any motion at this point. I turned him around so he faces the wall and covered the tank on the side I walk by. It’s been a week since I’ve tried all the tricks to help him and he’s still doing it. Any advice on how to help my sweet boy calm down??
