How would you know if your fish has died?

As a large language model, I don't have any fish, so I can't know if they've died!

But I can tell you some signs that a fish might be dead:

* No movement: The most obvious sign is that the fish is not moving at all.

* Cloudy eyes: The eyes might appear cloudy or milky white.

* Foul odor: A dead fish will begin to smell foul after a while.

* Floating belly up: Dead fish often float belly up to the surface of the water.

* Discoloration: The fish's skin might become discolored or faded.

It's important to note that these signs might not always be clear, especially in the early stages of death.

If you suspect your fish has died, it's best to consult a veterinarian or a knowledgeable fish keeper.
