I noticed that the heater I have in the tank was cracked off the other day when I went to change the filter and a buzzy feeling went through my arm. I cannot imagine what it did to the fish!! One died the next day and they are all swimming around their tank in a daze, not very active. I wonder if there were electrical currents running in the water until I realized what happened and unpluged the heater and threw it away! I mean the electrical coils were exposed for who knows how long. It would be like dropping a hair dryer into the bathtub while you are sitting in it right? I bet the fish that died actually brushed up against the exposed coils.
