Are all rat snakes aggressive?

[Jus1More]

I own a mandarin rat snake myself and while very different, more active and a quick mover she isn’t aggressive at all. I’ve been tagged by her once and it was the first time I handled her after a few meals and she was and stillis a wee baby and it was totally my fault.

I’ve had her going on 6 months I think and not only is she gorgeous but very mellow every time I handle her. Hasn’t struck at me since that first time when I learned from my mistake and that was that. This species in my experience is a very shy species and she does spend a lot of her time hiding but I do catch her out and about at times. They are a cooler temp snake I don’t even run any heat source on the tank. I’ve heard they can be picky eaters and she went on one 4 week fast during her first shed with me since then she’s been packing away the mice and growing fast. She’s nearly tripled in size since I acquired her.

This is a question for Philly and Charis regarding Mandarin rat snakes. These guys would be my second choice in a rat snake but I have some reservations. 1)How are there habitat setting it up. 2)I have read they like it much cooler, so do I need a heat source? 3) are male calmer than females? 4) I read they get up to 4feet, is that for both males and females?
5) are they aggressive as babies or just defensive "nippy"? 6) are they docile and easy going when handling them
6) are they sqirmey when you handle them, meaning always trying to get away (like corn snakes). 7) are they good eaters? 8) can they live ok in a plastic bin?

And if there is anything you can add please do.....
I am asking this because I have found a male baby Mandarin (locally) that I can get for $375, so I am thinking about it...
