I've been using an aquarium thermometer in my tank for the longest time and today I noticed it was broken and the Mercury had came out when I saw the goldfish picking at it. My first question is are my fish going to die? And second are the Mercury balls harmful to the tank. I did an immediate water change because I know Mercury is harmful but I don't know it's affects on fish or if it does affect fish.
