I acquired him in April of 2012 and was told he was a late 2011 hatchling. He was 14" or 15" when I got him.

My first weight for him wasn't until August 7th of 2012 and that was 72g.

If he hatched Oct/Nov of 2011, then he's about 15-16 months old, so I would call that sub-adult.

I don't really know though what "late 2011" means. Maybe he's older, maybe he's younger.
