A Step Up

[Bite_Me]

Hi All,
I've had a ball python now for about 8 months or so and and relatively new to the snake world. I'm having a great experience with her so far, she's never bit me or anyone else, a great eater and very social.
I was thinking of getting her a companion so that she is not alone, but wanted something maybe a little larger in the 8' range (more or less). I understand that ball pythons are very gentle snakes and rarely bite, however do you guys know of other snakes with similar temperament that get a little larger?

I was looking into carpet pythons or blood pythons, however can these be in the same tank as my ball? also, are they harder to maintain?
