the smallest well cared for beardie i have seen was around 10 inches full grown (I think some lawson's dragon had been mixed into the bloodlines in the past) my beardie is approx. 1 1/2 - 3 years (they were guestimating the rest of them that came in were around 3, he is smaller and possibly the son of a couple of them) and he is approximately 16 inches. Personally i hope he grows a little bit (1-2 inches), but the conditions he was found in i'm supprised he's even this big. Today is day 23 of ownership of his and he's doing better...
