In a recent Mythbusters, it was determined to be "plausible" that mothballs can actually increase your car's mileage. If mothballs were placed in your gas tank, I suspect you would smell the scent mothballs as they dissolved and then burned. It doesn't sound like mothballs would "spike" your tank. How can you tell if your tank has been spiked? If you cannot tell, it probably doesn't matter.
Gold is an inert metal (not dangerous to fish). You can put it into a fish tank if you choose too.
