I would like to see how the fish behaves in a bigger tank where there is a larger dead point in the middle where the cart doesn't move at all. If it still likes to explore around maybe it does like the experience. A few years ago I saw a cockroach on a trackball that controlled a similar vehicle. You could chase around by visual stimuli so in turn you would control the cockroach. It was a bit perverse but very interesting at the same time.
