I totally agree with everything you've been told by Daybreaker and Jason....
You have a normal Colombian BCI, not a BCC (although it is possible your snake has some BCC blood in its "pedigree" somewhere, but without documentation of that from her breeder, there is no way to know for sure). But judging from looks alone, I'd say there is no BCC influence and your snake is 100% BCI.
BCI are not generally referred as red tails - at least not by those with experience. The true Red Tail Boas are BCCs.
BCI are in no way any less desirable than BCC. Mostly its a matter of preference, and there are some that always prefer pure locality BCC over BCI, but there are also those that strongly prefer BCI as well. The BCC are a little harder to find in the trade so they tend to fetch a higher price tag, but that doesn't make them more desirable.
A female BCI will reach about 7-8 feet and around 30lbs. Smaller or larger is not to be unexpected though.
Enjoy your baby - boas are amazing animals!![]()
