Hi,
I keep and breed Candoia. I also have an article I've sent out for publication, but can link it to you if you e-mail me.

I have a general care sheet here: http://nyexotics.blogspot.com/p/tear-care.html

You can find some cbb Candoia here and there, but there aren't a lot of breeders. I should have some C. carinata, C. paulsoni, and C. b. australis later this year. There are a couple other people producing some soon I believe.

As far as arboreal goes, Solomon Island Tree boas need an arboreal tank, New Guinea tree boas will do fine in a terrestrial tank but branches will be utilized, and ground boas are fine in terrestrial tanks of course, but they'll all utilize branches.
