not the smallest dwarf, but almost. I'd say they're one of the rarest insular boas in captivity, so why would you only get one? I'd get them for breeding purposes to expand the pure blooded captive population if anything (especially considering wild populations may be gone). They're Bci so basic boa caresheets work with some tweaking. They may prove to be more arboreal than say your typical Colombian and also may like cooler temps.
