No way to tell the hetness until bred. I have a snake (I don't wana call her normal) that is 250g that I'm patiently waiting for her to get to breedable size. I've jus been given some very interesting news which I hope pans out for me. IMO you should get another het pied from a more respectable name and breed in the future. Pieds go for a pretty penny. Have fun with your balls!
