All of my deremensis(CB and WC) were, compared to other chameleons friendly. Thye wouldn't shy away, and they would come up to me to feed. They are all nice. My veiled is the meanest veiled I've seen (except for this 19" WC female I saw 10 years ago - my GOD was she evil).
As nice as the deremensis are, they get moody. When in breeding season(red lips & very roamy)they can be nasty. Both my males have attacked me during breeding season. One tried to bite, the other simply stabbed me with his horns,and broke the skin in the palm of my hand. Amazing power they have in behind their heads... hurt like hell too.
Now, my male veiled is easy to handle. When I used to come in, he would go from gorgous colors to ugly, and hide. Now, he brightens up when I come in. Took him over 3 years, but he finally recognizes that I'm there to feed him, not impale him on an acacia thorn. I can handle him now, I just lure him ontomy hand with food. Never tries to bite anymore - as long as I do not put my hand to him. It's gotta be on his terms, and he's cool.
I would have to say that out of all the chameleons I've delt with, deremensis are the most consistent.
