I'm not going to call myself an expert by any means...I just read as much as I can and learn from local breeders and other hobbyists. Also I find that there seems to be quite a few educated people in these forums....
but I am going to have to disagree with you in the fact that they are unable to become very dosile with humans.
The "friend" of mine actually is a local breeder with his masters in herpetology, he has worked with all sorts of reptiles for over 25 years and currently keeps 200 animals in his home. He also is licensed to possess venomous snakes as well as a few other animals forbidden to the public. He received his first pair of brown basilisks in 1988 and has been sucessful in keeping and breeding them since.
The basilisk he "put to sleep" was picked up very slowly and calmly out of it's tank then gently placed on his forearm...all he did was gently stroke it's head until it closed it's eyes...it continued to sit still and would occasionally open it's eyes to see what we were up to. After the head stroking stops the basilisk is free to jump from the arm or climb up on a shoulder...but he's content on the forearm. This basilisk will also eat from your hand as well.
I would agree that this is a very rare case and is not likely to be possible with all basilisks but I would believe that it could be possible with enough time and energy and patience to end up with a fairly tame, calm basilisk.
Thanks for the caresheet though, it was actually very helpful. As well as clearing up the forest soil issue...they are currently on pine shavings but possibly when the snow melts they'll get a nice forest bedding.
