Babies are hissy. Mine rarely strike, but hiss up a storm. They tend to mellow out somewhere between 12-18 months. Then they are ultra tame (in my experience.) As youngsters, they never liked to be disturbed, especially when hungry. But they calm quickly when comfortable in a new sitting/hanging spot (IE from the cage to your hand.) Thats when you are most prone to a strike, initial contact until they are fully out of their enclosure. Once out, see my comments above on being puppy dog tame.
Mine seem to prefer cooler conditions than the columbian
BCI's I have (88 high, 70 low). They tend to keep at 88-89.5 after a meal, and 3 days later, they seem to maintain low 80's body temp (83-84 F). This has been the case everythime I check on them with my infrared tempgun

.
Also, humidity is good to keep between 40-65%. They shy away from standing water, but a good moist hidebox with spagnum moss will get good use, especially when a shed is coming. They typically like climbing a lot when young, and about half as much as adults. Big females tend not to climb at all, but males seem to climb forever. Mine are mostly nocturnal, but they do enjoy coming out in the evening and basking in the sun as it shines through the window. Once the sun goes down, they head back to their hideboxes until lights-out. Mine enjoy coming out of their enclosures, and a few seem to 'seek' some outside time (mostly males.)
Also, you should be aware of males fasting during breeding season. Mine tend to fast even if they are not cycled. Longest fast to date was over 160 days! My females NEVER and I do mean NEVER refuse a meal. They are my garbage disposals for when the males decide not to eat.
I have never seen a specific caresheet for
Hog Island Boas, and the above info is just from my memory. I have been raising/breeding them for 9+ years now, and these are the major differences I have seen/experienced. I am sure I am missing some things. If you ever have need, feel free to drop me a PM and I will help where I can.
Good luck on those two new babies you have coming. They will bring you many years of happiness!
