So one of my new guys is consistently displaying aggression every time I check on him or try to clean (let alone try to handle!) He was in shed for the last week, so I assumed that was all it is, but he is done and still reeeeallyy pissed. He's now struck at me 4 times. I haven't dealt with aggression before in any of my snakes so I'm not quite sure what to do. Suggestions?

All conditions are good, he's on heat, humidity is up, plenty of water, etc. He just shed and had a huge poop, so everything is good otherwise.
