Decapitation - cutting off the head
A heavy, sharp object such as a knife breaks the spinal cord in a second and the fish instantly die without unnecessary torment. This method of euthanizing fish is found by many fish owners as the best, fastest and, therefore, the most humane. It can be used for all species.
When Disease occurs: The most appropriate time to consider euthanasia, is when a disease occurs. In cases when diseases are highly contagious, or very hard to treat or even untreatable, then the old adage of one bad apple in the barrel, can be synonymous with one sick fish in the tank.
Humane killing requires that the fish is stunned (rendered instantaneously insensible) before being bled out. Fish should remain in water until immediately prior to stunning. There are two methods that can be used to stun fish caught by hand: percussive stunning and spiking (also known as pithing or iki-jime).
If your fish has been suffering from a severe illness and none of the treatment methods have been working, euthanasia might be the best choice. It may seem harsh to end your fish's life, but it might actually be the kindest thing you can do – especially if the fish is stressed and in pain.
There is nothing strange or wrong with mourning the passing of a living being that was important to you, indeed it is a natural reaction.

As experts were quick to point out following the movie's release, flushed fish typically die long before they reach the ocean, going into shock upon immersion in the toilet's cold water, succumbing to the noxious chemicals found in the sewage system, or—if they make it this far—finding themselves eliminated at a water ...
Once the gills don't move for 10 minutes, the fish has been successfully put down. If you still see gill movement after 30 minutes, add more mixture. It may take some time, but many aquatic life experts find this the most comfortable method of euthanizing a sick or injured fish and in accordance to ethical standards.
At present, Sodium Pentobarbital is administered intravenously. This is the most humane way to euthanize and should cause no pain or discomfort. The pet falls asleep into an anesthetic state never to wake up.
In case you have a bigger fish, more species, or do not have enough clove oil, then adding Alka Seltzer tablets to the unconscious fish is a humane way to put them down. This is a great option for euthanizing the fish at home since both clove oil and Alka Seltzer are readily available.
Around 0.4ml of clove oil per litre of aquarium water is sufficient to cause death in exposed fish. The clove oil should be mixed with a little warm water first before slowly adding it to the aquarium water containing the fish. Do not add all at once as fish get excited – add the clove oil mix over a 5 minute period.

Fish become frustrated and unhappy when kept in cramped bowls or tanks. House fish in a large filtered tank. All tanks should have a pump to keep water flowing continuously.
As with humans, the only time animal euthanasia is justified is if the animal is suffering as the result of a debilitating disease with little hope of full recovery.
Why Is My Fish Swimming Upside Down? If your fish is swimming upside down, it has a problem with its swim bladder. Your fish has stopped being able to control its swim bladder and has got stuck with too much air inside it. The reason for this could be constipation, a poor diet, eating habits, or an infection.
Aquarium or pond salt is the safest choice for fish systems. And make sure it is SODIUM chloride “salt.” POTASSIUM chloride is toxic to fish and will kill them. Do not use marine or coral salts in freshwater fish systems.
