Can a moray eel electrocute tank water?

No, moray eels cannot electrocute tank water.

Here's why:

* Moray eels do not produce electricity. They are not electric fish like eels in the family Gymnotiformes (e.g., the electric eel).

* Electrical conductivity in water: While water can conduct electricity, the presence of a moray eel alone would not alter the water's electrical conductivity enough to cause a shock.

It's important to note that:

* Aquarium equipment can be a source of electrical hazards: Always ensure that aquarium equipment (pumps, filters, heaters, etc.) is properly grounded and in good working order to prevent electrical shocks.

* Saltwater can conduct electricity better than freshwater: This is why it's especially important to be careful with electrical devices in saltwater aquariums.

So, while you don't have to worry about your moray eel turning your aquarium into a shock hazard, always be mindful of electrical safety around your tank.
