Is this normal? First time corn owner.

I have two corns, one Malt he's a Caramel of some sort, he's grey and brown saddles. I also have a Hypo named Candy who is Grey with red saddles and yellow dots in between. Interesting behavior, Candy loves to hide and has no issues on the cold side, but Malt loves to be warm. It kind of concerns me, is this anything to worry about? Candy does occasionally move to the warm side, but rarely. He's much more relaxed and still alert, but Malt is super hyper active. Is this normal?

They can have different personalities. As long as your temps are good, I see no reason to be concerned.

People all act differently from one another and have different personalities. I don't think it is a stretch to imagine that snakes are the same way.

You did not mention in your original post if both snakes have their own enclosures or if you are cohabitating them. I think we all assume they are individually kept because that is most appropriate and what most of us do. However...... you did not specify. I've seen snakes kept together act differently than snakes housed independently because they don't have to compete for territory, heat, preferred spots...etc.... If your snakes are housed independently, then I would agree with the other posts. However, if you are keeping them together, I would urge you not to do that and that could explain what you are describing.
