HI Brandeis, your baby is adorable
it is a Pagona Vitticeps (Latin Genus and species) primarily because those are the only ones Petsmart carries. It looks like you did get what THEY refer to as a fancy dragon because of his markings which are lovely by the way, but it doesn't change his base Genus and species. There are about 8 other species of bearded dragons but most of them u can't buy thru any legal pet trade.
Petsmart employees tell ppl the company line of 3to 6 month old dragons, after a phone call to their headquarters last month, I found out the top of the chain just plain lies. Thank u for saving a beautiful dragon from Petsmart!!!!!
