Here is an older photo of my female. She is not as clean as my male. She is covered in those pepper spots including on her belly. Does your boa change colors? BCC can change color depending on time of day and mood like many other locality boas. The only thing that makes me think he may be a cross is the color of the tail like darkcomesoon points out but Im giving you the benefit of the doubt. The head shots will help.
It might help to mention... The other boa (his brother or sister) had an orangish tail too. More orange then mine.
