Delicate Balance is an interactive robotic work designed to allow a fish to determine the direction that it moves along a wire, so it can explore it's environment beyond the limits of the tank. Bettas have excellent sight giving them the ability to see far outside the tank.
I wanted to give this Betta Splendons (Siamese fighting fish) the ability to virtually leave the tank by moving it. The water is heated to the natural comfort level of the fish, a tropical 78-80 degrees Fahrenheit. The fish determines the direction by crossing a break - beam which activates the motor to move the tank in the direction which the fish looks to the outside world.
