Just a thought, but does AC remove hormones/pheromones? If I remember correctly, fish secrete hormones (or other organic chemicals) to signal to other fish. If those chemicals build up in the tank, it is pretty determinable to the health of the fish. Not saying a water change wouldn't solve it, or that AC is better then a WC. Just thinking out loud...
