In my experience I would say they are a fairly laid back snake that doesn't stress as easily as a ball python. HOWEVER, this is a generalization and no snake will do what you expect every time you expect it. A tag from a 3 foot ball python is one thing, a tag from an 8 foot boa can be quite another. Respect what the snake is capable of, plan for it....that's always best I think.
Most boa's seem to have a very good feeding response, a very strong strike capability and a long strike range. Care needs to be taken on feeding night as most boas are quite "anxious" to get to their prey LOL.
This is a 16 year old female Colombian boa (boa constrictor imperator). She is approximately 8.5 to 9 feet in length and pure muscle every inch. I think with this species it's very important to have them sexed as males tend to be smaller and if you do want a female you should be prepared for the possibility of a very good sized snake.2: Whats the average size I should expect it to get? and whats the max possibility it could get up to.
There are a number of housing options. What is appropriate for a hatchling boa isn't right for a snake like the one pictured above (who has her own custom closet rehab enclosure).3: What kind of enclosure, hides, substrates, size of emcolsure, temperatures does it need to be maintained?
For substrates with our boas we use a combination of aspen and cypress mulch. This helps hold humidity in their larger enclosures and we find stands up well under their greater weight than pure aspen would. The large female boa does not have a hide but does have areas of her large enclosure where she can retreat out of sight. The smaller boas have dark black rubber or plastic hides (one on the warm side). We keep the boas a bit cooler than the ball pythons and only offer them supplemental heat during cooler temps or when they are digesting a meal (they live in a room with naturally high ambient temps).
