While I wouldn't by any stretch call myself a pro, I have done a lot of reasearch, and have been successfully keeping ackies for the past couple years, so I might be able to help. To me, ackies are everything thats great about monitors, just in a more manageable size. They can also be a little cheaper to feed, as breeding a tub of dubia roaches will cover a lot of their dietary needs. As for interacting with them, that's entirely a measure of how much effort you put in, though I would say in general that ackies will always be a little more flighty than their larger counterparts, simply because they never get large enough to totally lose that "everything that moves wants to eat me" attitude. This is not to say they can't be tamed, and I have never put much effort into it with mine. Yet they still come running up hoping for food whenever I open the door. And have almost no fear of my hands.
