your going to want to work with him a lot as colombians are known to be the less friendly and most aggressive of the tegus
i dunno though i kinda have the opinion that the more you handle them they don't get tamer they get more stressed out and thus why they don't try to eat you. but i will handle godzilla and ill just see how it goes if he is showing signs of stress ill stop
i bought one of those 125 watt mercury vapor uva-b bulbs for him today aswell
he ate a scallop and a small convict cichlid
