This.I don't keep variabilis, but I'm willing to bet that even a knowledgable person cannot distinguish between individual highlands and southerns reliably, regardless of what some might claim.
The way to tell the difference between locales is to purchase them from a breeder who knows the lineage.
You should check frogdaddy.net I think he may have some.have you guys seen any variabilis highland available? i used to be able to see the marketplace, but can't any longer. I have an adult highland male and would like to pair him up in the 18x18x12 that he's lived in for years now
