I keep Savu pythons. Tried my hand at breeding them this past season but unless the male was really sneaky about it, I never caught a lock.
These guys are fun to keep; very active, outgrow the baby nippiness quickly, semi-arboreal, not shy, etc. They are voracious and will readily take f/t mice, very small chicks, or rat fuzzies.
I run mine in tubs with moderate humidity at 75*F to 88*F and they do just fine. They have adapted to living all over the tiny island of Sawu so they don't have narrow husbandry criteria like a BRB would. Set them up like a carpet python or boa imperator.
