I'm sorry, I didn't even see this question! Males generally stay smaller than females, like most boas and pythons, but each individual is different. I'd say a good average for a male BCC would be around 5-6 feet max but there are always exceptions to the rule. Boas are very different when it comes to their prey in the wild. Therefore their bodies digest and process fats very differently than pythons. This is the reason it's strongly recommended to never over feed a boa. Twice monthly feedings or a prey item that is smaller than what you'd feed a python of the same size/age is recommended for juvies. Adults do not need more than a large rat monthly. These boas can suffer from fatty liver disease and other fat related issues which greatly shortens their life. Birds are the healthiest food item for these boas since they are lean and easier on their systems. In the wild these boas spend more than half their lives in the trees, taking birds and lizards mostly. My 2 have been slow grown in this way, but my female is still quite large with a massive head. Tho she's never been round. They should always maintain a muscular and rectangular shape. My male seems small for a 5 year old at less than 5 ft, but he's quite healthy and has the perfect shape and tone to his body. He is not done growing by far, but he is growing at a healthy rate. Too many people over feed their boas and end up with fat, unhealthy boas. Even common BCI should not be round like a python. I know I went off on a tangent here but I always try to explain these points to anyone asking about boas. A boas feeding and diet is the most important thing in my opinion.
