Argentine boa coloration
 

I've had a young argentine boa from a reptile show. When purchased I was told it was 4 months of age.

Now I've had him for about a year the tail is darkening but the body is not black and white as I thought it would be. Now regardless the color he's one of the boys now so I don't mind lol but I am wondering if the rest of his body will continue to darken as well.

Any information would be much appreciated.

Thanks
