Yeah, that was mostly what I was thinking to try first. Vertical spaces, hiding spots, high humidity, light sources primarily for the plants. I’m thinking under tank heat in a limited spot, but if they’re full arboreal, that might be of limited use. Adding in a loose substrate, I’ve seen, I think it was two notes suggesting some burrowing, but I’m not sure. They may have been escape attempts, or I misremembered.
The temps worry me abit. There are surprisingly wide ranges in Central America, especially as this species is noted in low and montane regions.
I know there are keeper/breeders of this species and it’s relative, Ungaliophis panamensis the banana boa. I just hope some of them will be willing to share some of their experience.
