If the eyes appear sunken or cloudy, your fish is likely dead or dying. On the other hand, if the eyes look bright and clear, it is probably still alive. If your fish has jumped out of the tank, don’t panic—if you catch it and put it back in the water soon enough, it may recover.
How can you tell if a fish is in shock?
If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress. Talk to your veterinarian about treatment and look into what may be causing the stress and alleviating it.
How do fish act when they are dying?
Your fish will not be acting like they normally do. They may seem distressed, have no appetite, hide, have nicked fins or sores. If your fish is near the surface gasping for breath, this means it’s probably not getting enough oxygen. This can happen due to poor water circulation, gill damage, or toxins in the water.
Does fish die from shock?
When you perform a water change with colder water, the fish in your aquarium go into a thermal shock, which leaves them extremely vulnerable to disease. A fish that goes through thermal shock will not move a lot, lose its color quickly, and may die almost immediately after a water change.
Do fish float if they are dead?
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 revive a fish for shock?
Place the goldfish in a container filled with cool water from his tank. The cool water contains oxygen and will help to revive your fish. Some experts also suggest placing your goldfish right back into the water in his tank, even if he appears dried out.
Why is my fish not moving but still breathing?
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.
Is it possible to save a dying fish?
Most dying fish can be easily revived with changes to the water. Maintaining water quality is essential to keeping your fish happy and healthy—and alive. You can buy a fish tank water testing kit at most pet stores. These tests can help you identify any problems with the water, such as high ammonia.
How do you comfort a dying fish?
Clove oil is a sedative which at high doses, can be used to euthanase small fish. Unlike veterinary anaesthetics, clove oil is readily available from most chemists. Around 0.4ml of clove oil per litre of aquarium water is sufficient to cause death in exposed fish.
How long does it take for a dead fish to 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 fish recover from stress?
Once the panic has passed, the fish must also regain its natural balance. This can take hours or days, even after only a short period of stress. Long-term changes, such as a poor or unsuitable environment, are handled with the same initial response – an alarm message to escape.
How do you destress a fish after water change?
Saving Dying Fish After Water Change

- Aerate the Water.
- Use Chemicals.
- Use Aquarium Salt.
- Use a Carbon Filter.
- Avoid Huge Water Changes.
- Use a Dechlorinator.
- Check Water Temperature.
How do you destress a fish?
Ways to Reduce Fish Stress
- Change water frequently to keep nitrate and ammonia levels low.
- Check water temperature for consistency regularly to prevent stressful fluctuations.
- Provide an optimal filtration system like the Fluval Underwater Filter that captures debris and bacteria while ensuring proper oxygenation.
Can a fish play dead?
Some species play dead to fool other fish, often targeting scavengers as a food source. The Central American cichlid is a perfect example. In other species, though, this behavior might hint at a health issue.
How long can a dead fish stay in tank?
It depends on what the cause of death was. If the water quality was perfect and all other fish, including members of its own species, appear OK and look free of disease you could restock within a week. Leaving it for a full seven days is best, as if others die within that time you’ll know there’s an underlying problem.
Why is my fish dead at the bottom of the tank?
Poor water conditions
Whenever the tank has bad water or water not suitable for the fish’s health, it leads to their death. Poor water condition is a big reason why most of the fish die in a fish tank. Therefore, if you are an aquarist, the priority should always be to maintain the water quality.
What to do after fish dies?
5 steps to take when a fish dies in your aquarium
- Remove the corpse of the fish from the tank.
- Test the aquarium water for raised Ammonia levels.
- Change a portion of the contaminated water.
- Pour in a beneficial bacteria starter in the tank.
- Investigate the cause of death.
Why are my fish acting weird after water change?
Osmotic shock happens when the fish is unable to regulate its uptake of ionic compounds, which leads to too much absorption or too much release of fluid. Impaired osmoregulation then causes a condition known as dropsy, which leads to fish swimming erratically after water change.
Can fish recover from thermal shock?
Set the water parameters to ideal conditions, including temperature, and keep it close in case your fish displays symptoms of temperature shock. Placing the goldfish into the treatment tank immediately will allow it to stabilize and recover.
How do you tell if a fish is asleep or dead?
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.
Why do fish just stay still?
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. Other possible causes are overfeeding and improper water quality.
