Agni just hit the 17 inch mark, but he still has the body and head shape of a baby.
he's not looking anything like any of the full grown dragons ive seen on here. his head isn't nearly triangular enough, the base of his tail isn't thick enough, and his body certainly isn't like that of adult dragons I've seen.
Do you have pics ? Beardies all have slightly different bone structure and body shapes. Some just have a more lean look. Plus, he's still growing....he will change, but he may also be one with a more narrow head, less fleshy than others.
