Diseases of aquarium fish-treatment

Aquarium fish disease is a very bad moment in the life of an aquarist. Even skilled aquarists with great experience are not insured against this trouble.

However, most diseases are well treated. If you are extremely attentive to the inhabitants of your aquarium, ready to look for information in special literature and online resources, you can successfully cope with it with a bang.

Ichthyopathology – the science that studies fish diseases – subdivides them into infectious and non-infectious. Infectious diseases are divided into infectious and invasive. Infectious diseases are caused by bacteria, viruses and fungi.

Invasive – parasites of animal origin.

The parasites, in turn, can be divided into two groups – unicellular (protozoa) – flagellates, sporozoans, ciliates and multicellular – helminths and crustaceans. Non-contagious diseases occur when optimal conditions for fish are disturbed and mistreated.

Refers to chemical factors. The first symptom of aquarium fish disease is difficulty breathing in fish. The gills, as a result of prolonged exposure to chlorine in water, brighten and become covered with mucus.

Fish rushing around the aquarium, possibly trying to jump out of it. Then, become lethargic and do not react to anything.

Death can come suddenly and quickly.

To avoid such consequences, chlorine disinfection should be carried out. Each time, changing the water in the aquarium, you need to check it for the level of chlorination.

In the case of the first signs of poisoning, you must immediately pull the fish into another container with clean water.


Nitrates are relatively harmless to fish, but sensitive species are sensitive to nitrates. When poisoning with nitrates pale gills, suffocation occurs, the fish become lethargic.

In case of poisoning, it is recommended to change the water more often and add 1-0.5 tsp to 100l of water to the water.

Remember: Anyone can get sick, even goldfish. Aquarium diseases can occur for many reasons. To establish the diagnosis correctly, answer the following questions: How has the behavior of the fish changed?

What has changed in the habitat before infection, perhaps the source of infection has become the new “neighbors” or algae?

Has the water temperature changed in the aquarium? Was there a release of harmful substances near the aquarium? Pay attention to the feed, especially if you have not used feed of this brand before.

Has the pH changed? May be triggered by an acid or alkaline disease.

And this still does not list all the factors that could harm aquarium fish.

The maintenance of aquarium fish directly affects their health and appearance. After the source of the disease is detected, determine whether it is infectious or not.

If the symptoms say that the disease is non-infectious and does not threaten other inhabitants, then you treat only the sick fish. Otherwise, all aquarium animals are treated.

THIS PROCESS is carried out in a separate quarantine aquarium, and the main one is thoroughly washed and disinfected. Obesity. If the fish for a long time to overfeed, give them a monotonous food, then they may happen obesity.

This seemingly harmless disease can cause a number of acute problems related to the health of your pets.

The kidneys and liver are the first to suffer, then the rest of the organs, the fish may even become infertile. What is obesity in fish? The answer is simple: watch the fish, if it is observed apathy, lethargy, the sides become much rounder, it began to move less – these are signs of obesity.

For the prevention of overweight, it is recommended to feed the fish in small portions several times a day, at about the same time, including high-quality food in the fish ration, alternating between them.

It is advisable sometimes to give the fish live food and periodically arrange fasting days for them. You can reduce the number of feeds from 2-3 to 1 per day, and it’s better not to feed fish at all, 1-2 times a month.

Hypothermia. Reason: too cold water in the aquarium. In fish, the activity of the swim bladder is disrupted, and they fall to the bottom.

If time does not take action, the fish will die.

Treatment: it is necessary to raise the temperature in the aquarium to the optimum. But not abruptly, but gradually – no more than 3 degrees per hour

Injuries. Fish can get hurt about the interior of the aquarium, during transportation, as a result of a fight with other fish.

Treatment: In principle, as such, treatment of injury is not required: the fins and the skin will eventually recover on their own. But infection can penetrate through the wounds. Therefore, the injured fish for 10 minutes should be put in a bath with 5% salt solution.

The procedure is repeated 3 times a day for 2-3 days. All this time, the fish should be in a quarantine aquarium.



Is it difficult to keep aquarium fish? Such a question is often asked by novice aquarist lovers. They are afraid that they will not cope with the care, feeding, settlement of pets.

Like any living creature, aquarium fish requires attention and care, but how to create comfortable living conditions for it, if you don’t know enough about the aquarium business? In this case, your pets can become unpretentious aquarium fish. They are easy to maintain, unpretentious fish are considered very hardy, tenacious, get used to the person.

If you are very busy, and you do not have enough free time to care for animals, then the most unpretentious aquarium fish will significantly reduce the time for employment of the aquarium.
