It makes me nervous about buying hets, but if you buy from someone you trust, it's perfectly safe. I'm really choosy about who I buy from even if they are visual morphs. I want to know that I'm getting is what I'm paying for!
To the OP, if you ever see PH Albino (or any recessive morph) that mean Possible Het Albino, usually 50%, but could also be 66% het.
