I figured I should put some more info about these guys. Males usually reach 7 to 8ft (there are exceptions and very well fed male may reach 10ft, it's unlikely with these guys as both parents are not even 8ft).
Females will get 8 to 10 ft (exceptionally large females could reach12ft).
Neither of their parents bite, they are calm enough for kids to handle.
The care is about the same as for boas, they need a large tub to soak though.
Here are some pictures of their parents:
All the babies are getting ready to shed and should be available for sale in 2 or three weeks.
