Well, out of my whole group, my BRBs are definitely my favorites. They're very engaging, active, and they just SEEM intelligent to me.
General care is pretty easy once you get your levels right, and troubleshoot ahead of time. Humidity's obviously the big one, babies especially need almost 100% humidity or else they can really suffer. I accomplish this by using cypress mulch and placing their water bowls over the heating element. I use flex watt on most of them. Also, I mist about once a day, but I probably don't need to. The bowls over the heat really do kick out enough humidity, I just like to mist.
The other major important thing is to remember that they're cooler than a lot of other snakes. They suffer majorly if the hot end gets over 85. I keep my surface basking temperatures about 82, and the cold end can get down to about 74 in their tanks, they tend to be happy campers at about 77 degrees, I've noticed. That's their favorite hang-out zone.
Feeding is a piece of cake, they usually have GREAT feeding responses. Try to find one already ON f/t obviously, but all of mine are champion little feeders. The adults get fed in their cages at my house, on newspaper, and they just poke their heads out their hides and go to town. The babies are put in little butter tubs and get their rat pinks. I usually leave them overnight, but I think they all eat pretty quickly.
They can eat a bigger meal than you think they can, too. Neonates come out usually ready for pinky rats, and you usually offer them something 125% to 150% their biggest girth. The growth rate on these guys is absolutely PHENOMENAL.
Most care sheets say that they are partially arboreal, but it really depends on the individual. I offer climbing areas for my guys, but only a couple of them are real climbers. They are strictly nocturnal, so while you won't see them during the day, they're crazy out and about at night, usually. Also they get those high white sides at night and become even extra pretty.
All in all, they're a ton of fun, aside from losing our big girl, Ember, last year, we've never had any trouble with them aside from the occasional brat who decides to be a bit difficult to switch to f/t. They all came around within a few weeks, but a couple of them have been real pains about it, lol!
