Look at your fish very carefully. Observe whether his eyes appear alive or if they have turned gray or sunken into his head. If your fish’s eyes are gray or sunken in, he is deceased and most likely has been for several hours.
When fish die do they float or sink?
Most fish are slightly denser than water, so sink immediately after death. However, like a drowned human, they become more buoyant over time as bacterial decomposition produces gases inside the body. Usually, enough gas builds up in body cavities to make the corpse float, like an inflated balloon.
How do you know when fish will die?
Last but not least, a key sign of death is when the gill flaps or operculum stop moving. The gills are what keep the fish alive by providing oxygen and removing carbon dioxide from its system, so many hobbyists turn to the gills to observe for signs of life.
Why is my fish not moving?
Listlessness: If your fish seem tired and lethargic, it can be as a result of many factors. One common cause is improper water temperature. If your fish’s water is too hot or too cold, they will be very inactive. Check your heater and verify that your aquarium is at the right level.

Why is my fish immobile?
Poor water quality, including excess nutrients, ammonia, or a fluctuating pH, can cause koi to become sluggish and immobile. What is this? One of the leading causes of koi immobility is poor water quality. High concentrations of nutrients can stimulate pathogenic growth in your pond and reduce oxygen levels.
Why is my fish laying down but still alive?
It’s perfectly normal for fish to rest and sleep while lying at the bottom of the tank. Healthy fish will do this between sessions of active and energetic sessions of swimming. You should keep the lights on your aquarium on a diurnal schedule (8-10 hours of light per day) to encourage your pet fish to rest.
Why is my fish floating but still alive?
Positive buoyancy disorder, where the fish floats at the surface or on its side, is the most commonly presented form of swim bladder disease, especially in goldfish. Most likely, the cause is overinflation of the swim bladder.

It’s pretty easy to tell when fish are sleeping: they lie motionless, often at the bottom or near the surface of the water. They are slow to respond to things going on around them, or may not respond at all (see some sleeping catfish here). If you watch their gills, you’ll notice they’re breathing very slowly.

The size of your fish tank determines how fast its water will get polluted if a dead fish is left in there to rot. A small fish decomposing in a 30-gallon aquarium will likely take a whole day before the water becomes foul. However, a fish that has died in a 5-gallon tank could pollute its water almost immediately.
