I have a female Bolivian, I keep her ambient temperature at 78-80F with a warm spot of around 90-92F. I was also having trouble finding husbandry requirements specifically for Bolivians, so I researched climatological data of their native region, where the average temperature is around 85-86F. so, in order to provide a temperature gradient, I settled on approximately 5 degrees low for the ambient, and 5 degrees high for a hot spot. I provide a standard target humidity of 55% - 60%, and bump it up to around 65% - 70% for shedding.
Bolivian boas are neither BCC nor BCI. They are Boa Constrictor Amarali (BCA).
