i have a tokay i have had for about 4 month and its a baby. So far its tamed down alot. Now it will alow me to pet it, like accually pet it on its back, some times if i reach in coming in on the side. It wont run. But if i continue and go anywhere near the head it will bark and jump. its a big improvement from what it first did. Yes my tokay hides in a cave during the day but still lets me pet him at night. I think they may tame down more if you handle them more then i have. I ussually pet him every other day, as i pet him and try to get him to move down the tank when i feed him. I like to watch him eat crickets so i get him to move down by the bottom so i can watch him to eat, and yes mine will eat with the lights on and me watching. Mine will only eat 2 every other night, they are large to medium sized crickets i know they are a little too large for him but he dont go for the smaller ones.
i hope some of this helps you
i am a new tokay owner also
i think they are great. mine will shake his tale and jump on the crickets when he eats its so cute
