Don't have a BRB, however 3 of my constrictors spend most of the time in the water which is on the cool side, especially in the winter, regardless of humidity; my oldest Coastal, BCI Boa, and Jungle Carpet.
Plus my new BCC started out in the water, or rather tried. As you can see he is way too big for that bowl!
