Beautiful snake. Are they as hard to care for as I hear? I almost got one a few years back but the high humidity requirments scared me away.
Actually she's relatively easy to care for, but she does require higher humidity. She was one of my first snakes, and I was as well very nervous that I could provide the proper care to keep her healthy. At first I had her on cypress mulch, because that's what the breeder recommedned. But she had trouble shedding on a few occasions, even when I was misting her a couple of times a day. So I switched her to the dirt that comes in bricks and fills out with water, and put some of the flukers Sphagnum moss over that. Now she sheds in perfect full sheds each time, and I only have to mist her every 2-3 days.I would recommend much higher humidity when they are babies, but you can decrease misting as they get older, atleast I've found that to be the case with mine.
She is about 3yrs old now, and roughly 3 1/2'. And she is the friendliest, most calm snake I own. I have incorperated my own husbandry techniques, as they seem to work better than other methods I have read. And that's really the only way any breeder knows how to care for their snakes, is by doing what works best.
I would recommend Brazilian Rainbow Boas to a dedicated owner, because they are not your average snake to care for. I have had a few years of changing my husbandry practices, and I have pretty much figured out what works best for my individual snake. My advice would be to do some research, and find a snake with a good temperment. If you have the time and dedication to get one do, it and don't be intimidated because you think they are too hard to care for. As long as you understand that they require a little extra attention you should do fine, humidity, specific bedding, and a good soaking when they have trouble shedding.
Again this information comes strictly from my experience with one Brazilian Rainbow boa, so do all of the research you can. I hope this helps your question, and good luck if you decide to get one.
