No I actually bought mine from PetSmart for $50. It was labled "fancy" (lol) but I got her because she was the most active and pretty. I have noticed though that her tail stripes have been breaking as she's getting older.
It does look like a dunner....some of them have tail stripes but most don't from the pics I've seen. But the main characteristic is that the scales go in odd directions. Watch her beard as she grows. And if you want to arch her tail up high + get a few pics I can give you a 99.9% accurate [ ] guess on the gender.
Oh I know how to tell the gender (I've done it with a flashlight before... poor man's x-ray). I just know that baby male dragons can look like females. I've also noticed that she's been developing her femoral pores and they're pretty pronounced. So there is a slight chance she is a he.
But thanks anyway!
