It's not so much that they are devils. Columbians are different.They are much more wild. Capable of understanding you're not a threat after awhile, but not really able to view you as an aid. My tegus see me as something to look forward to, they either get some attention, get to explore, get to eat, get to harrass my cat, or get to bask in the front yard while pa does some woodwork. They quickly become the center of attention to your neighbors, friends, and family, and become the receptor of the family love VERY quickly. I come home to kiss the tegus before the fiancee. I honestly call them "the kids". I make turkey, shark steak, papaya souflee for the tegus, and fix top Ramen for myself. THey are amazing and you will spoil them rotten. The personalities are incredible, and anyone who debates that they are capable of personality is crazy and should come meet APollo. He's a drama king, a sweet heart, and complete HAM! Hold out and nab one of Bobby's tegs. I like the B&W more (good thing they can't read) than my red, and still await to delve into the Chacoan, and possibly a blue, but from what I've seen, they are a little defensive like COlumbians. Good luck Ernie, you're in for a wild ride Mr. Toad.
