Thank you
For Valkerie, here is an awesome webby if you haven't seen it already, it goes into lots of different boa localities and even talks about BCLs as well: http://www.riobravoreptiles.com/
And here is a visual of Colombian morphs vs regular CAs and CA morphs (I got my little male BP from Lynn at Boas and Balls): http://www.boasandballs.com/CollectionBoa.html
Notice how much darker/browner they are in comparison to regular Colombians who are usually a lighter cleaner brown-greyish? Also they are usually much more peppered than Colombians, though some Colombians are highly peppered. There are exceptions to CAs and Colombians of course, not every snake looks the same.
CAs usually grow smaller than Colombians and I have heard they are usually more nippy (exceptions to this of course as well). They have the same husbandry requirments as Colombians while BCCs can be a bit pickier/sensitive to their husbandry.
