If your koi starts floating on it’s side, and stops moving it’s gills (or if jumps out and you found it on the ground), you can revive them. Gently move them back and forth in the water to get the water flowing over their gills, and hold them in a water current.
What causes koi to die suddenly?
Most of the time, death in koi carp is caused by poor water quality. Making sure you have proper filtration, regular testing and maintenance will all contribute to the quality of your pond water, and therefore the health of your fish.
How do I know if my koi is dying?
Changes in behavior, such as erratic swimming, koi swimming upside down, abnormal feeding patterns or isolating themselves from others can indicate that your koi fish is sick. Physical symptoms like red gills, cloudy or popped eyes, and swollen abdomen are used to correctly diagnose koi fish diseases.
Do koi fish float when they die?
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 long after dying do fish float?
After the fish dies there is no more DO being ingested and the air in the bladder starts to dissipate, causing the fish to sink to the bottom. After a few days, the internal organs of the dead fish decompose and a gas is formed. This gas causes the fish to once again float.
Do dead fish float to surface?
When a fish dies, does it’s body float or sink? Depends on its swim bladder. If it has a gas filled air bladder that’s not popped, floats, until the body rots enough for the bladder to degas. No swim bladder, sinks.
How long does it take for a koi to die out of water?
Typical pond fish species, such as koi carp and goldfish, are not equipped with special mechanisms for surviving outside of water. They will quickly deteriorate within a few seconds of gill exposure to air, and will seldom survive past the 3- to 5-minute mark without access to water.
Do fish drown when they die?
When the water doesn’t have oxygen, they suffocate, just like humans suffocate when we don’t breathe enough oxygen. So, while a fish can’t die from drowning in water, it can die from suffocating in water due to a lack of oxygen.

The differences in acidity and dissolved oxygen, not to mention all of the fat, proteins, carbohydrates, and other minerals in the milk that might clog the creature’s gills, would quickly spell trouble. The animal would likely die within minutes, if not sooner.
How do fish look when they die?
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.
Can a fish be dead and not float?
It should also be noted that fish don’t necessarily always float when they die. For example, if a fish dies with little to no air in its swim bladder, the act of dying doesn’t magically make this bladder expand to increase buoyancy. In these cases, the fish will often sink, at which point decomposition will begin.
Why is my fish not moving but still alive?
If fish are experiencing acute stress (i.e., gasping up at the surface, lying on the bottom and not moving, or darting around the aquarium), you can be pretty sure that the water has been poisoned in some way. Maybe cleaning sprays got into the aquarium, or something released toxins into the water.
Can dead fish still move?
Very fresh fish still have their neurons fully intact, even though they’re dead. As soon as you add a bit of salt to the exposed muscles, the neurons are triggered and the muscles contract. So very dead fish will continue to move about until they use up all their energy stores.
Why is my fish upside down but still alive?
