This is a younger pic.
The tail on BCI's is usually more red when they are young. They are not true red tails, but this particular locality is what Vin Russo says is an example of what the perfect cross between a BCI and a BCC would look like. The Barranquilla boa scale counts are different from other Colombian BCI's, according to the book.
You can get a boa like this from Legacy Reptiles. They have a lot of the Rio Bravo Reptiles stock. Gus Rentfro of Rio Bravo IS the authority on BC's. In simple terms he is a boa GOD!
This is a picture that was maybe 2 months ago. You can see the colors hold. Maybe even better but the tail does go more orange/brown.
You should visit the Legacy Reptiles Facebook page and see what they have.
They do localities mostly, but also have morphs. They are top notch and one of the owners, Orlando, is a veterinarian that specializes in avian care.
Male BCI will be perfect for you.
