You know, compared to ball pythons, a lot of snakes probably seem more aggressive as babies because of how they deal with stress. We know ball pythons will ball up when they are scared as a natural defense, but most other snakes don't do that(at least not to the extent ball pythons will) and instead will react to their fear with their only other defenses--fight or flight! If we're holding them or they are trapped in a tub with a giant monster coming after them...well, that just leaves fight!
So if you have a high stress rainbow boa he or she will be more likely to nip at you to tell you to go away so you won't eat him or her! If you can manage to handle the snake without stressing it out, then you are less likely to get bit.
I have seen some really docile and sweet rainbows and a couple who were bitey, but most of the biting was really more out of nervousness than just being a mean snake. Just wanting the intruder to get out of their bedroom!![]()
Best way to know what they will look like as an adult is to see their parents! I don't like to buy my snakes unless I can see the parentsOh, and they look most iridescent in UVB, but the best in true sunlight!
Don't let them get too hot! That's a big mistake I see a lot of people make when they expect them to be like every other snake they've had!
