Hello I am just wondering how does one know the difference from the "Panama Farm Raised" pumilio and the "old line" pumilio? Is it a visual thing of is it something only known from the breeder telling you the line? Also which is the better frog to buy? I hear they are different enough that they shouldnt be interbred, how can the same frog be so different? I guess I really just need someone who knows a thing or two about the pumilio family to help me in my decision making.
