Great topic. I'm asking some of these questions and have a caging post going. I'm very glad to hear boas are much more active (in general) than the Royals. I like my son's snake, but the food refusal and hiding 24/7 sort of took the fascination of watching snakes away because I never see her. Now that she is not feeding, I only see her when we handle her. I love to take her out, but seeing them in their enclosure even if it's just lying motionless is so much more exciting to me.
Male Colombian BCI sounds perfect for both of us.
Lots of good help here!!
