I am sure that you got one of the "normals" from Mike's breeding. A shame because I really wanted it. :) Your gain......My loss. :) If you have what I think you do.......It is just a "normal" sibling to the true Salmontines. (Which are Argentine hypos) What you have is a cross. They will exibit traits of both species. Like you noticed. A different shaped head........An Argentine tail, etc. More than likely you boa will get darker with age. I personally think the normals from that breeding are great. Congrats on your new boa.
