Awesome Miguel, it's rare when you see an adult Hartwegi and rarer if ever that you see one with a nuchal hump. It seems like many buy Vieja's but lack the patience to grow them to their amazing adult form re-homing them at around 5-10 inches. I myself am included in that generality I'm putting out there. I re-homed my Synspila, Hartwegi and Zonatus all around the 10-12 inch range. The Sysnpila had just come into his own when I did, hopefully the next owner benefited from my lack of patience. Presently I'm raising 3 synspila hopefully I'll have the dedication to raise them into show stoppers.
