Are these captive bred at all? From what I've been told, no (which explains the aggressivness) but according to this (<!-- m --><a class="postlink" href="http://market.kingsnake.com/detail.php?cat=53&de=577966">http://market.kingsnake.com/detail.php?cat=53&de=577966</a><!-- m -->) they have some captive born ones. I'm tempted to get a few in the future to try at captive breeding them. I think they are very pretty, just need their attitudes worked with, and with captive breeding that can be done. I don't know...breeding tegus for me is still a few years down the road.
