Can there be an allergy to fish in the aquarium?

Allergies to aquarium fish are rare. The most susceptible to the development of the disease are people who have direct contact with fish food. The fish themselves living in the aquarium, as a rule, rarely cause allergic manifestations. This is due to the fact that their waste products do not enter the air and do not have direct contact with human skin.

Therefore, food is the strongest allergen, especially if it is made with violations of the technological process. The nutritional formula contains protein components, which are the strongest provocateurs of an allergic reaction.

In addition, the water in the aquarium and the installed filters accumulate the remains of protein food, therefore, an allergy to fish even to the aquarium water automatically becomes possible.

Causes of allergies

There are very few reasons for the development of an allergy to fish.

  1. The leading role belongs to protein structures, as a rule, of animal origin. These include dry food for fish feeding, which can be rubbed in the fingers. As a result, a large amount of dust is released in the air, causing allergic symptoms in humans.
  2. The second factor in the development of the disease is the aquarium water into which these proteins enter. When in contact with the skin, they cause negative manifestations.

General allergic symptoms

There are a number of indicators, the presence of which can be an indicator of the development of allergies. The main symptoms appear:

  • cough and sore throat;
  • irritation of the mucous membranes of the oral cavity;
  • the development of allergic rhinitis and conjunctivitis;
  • sore nose and frequent sneezing;
  • hyperemic rash all over the body;
  • gasping for breath;
  • wheezing in the lungs is possible;
  • a sharp rise in body temperature.

With the development of an allergy to food for aquarium fish, this can be expressed by someone symptom or be completely asymptomatic. In addition, one should not neglect the difference in the course of allergic symptoms among age groups and especially among children.

In babies aged 4-6 years, the development of allergies can be complicated, and in adult patients it can develop latently.

The course of allergies in children

All parents are worried if a child has complaints of poor health, coughing fits, redness and swelling. Some allergens can cause an asthma attack, in which an urgent need to hospitalize the child.

Very often, parents do not suspect that this symptomatology occurs in children with regular food for aquarium fish. The most common provocateur is a dry mixture of daphnia and gammarus.

Sometimes, in order to avoid allergic symptoms, it is enough to simply replace this food by switching to live or granular. The room in which the aquarium is located should be cleaned more often.

And, of course, you should consult with an allergist, who will give recommendations on keeping fish, so as not to risk the health of the child.

Rules for feeding fish with allergies

Allergy to Aquarium Fish

To prevent allergy to fish, it is important to know what kind of feed you need to purchase, and what its composition is. It is necessary to exclude such varieties as Daphnia and Gammarus, despite their affordability and ease of use.

  • There are many substitutes that are not inferior in terms of nutrient content and vitamin complex. After opening the package, the nutrient substance should be stored in an airtight bag, without access to air;
  • it is preferable to use live and frozen food (brine shrimp, plankton, coretra and bloodworms). Such food is considered to be the safest for people prone to allergies. In addition, this is also of great benefit to fish;
  • some manufacturers produce food for fish in special blisters for minimal contact with human skin. Even a frozen product with increased sensitivity of a person may contain a certain amount of allergens;
  • there are also dry types of food that practically do not provoke the appearance of allergies, for example, granular;
  • in addition, food in tablet form and flakes is widespread. They are almost identical in composition, but feeding with flakes deteriorates the quality of the aquarium water. The tablets practically do not change the structure of the liquid, moreover, they are eaten with pleasure by the fish living at the bottom.

To limit contact with possible allergens during feeding, it is necessary to give food only if the rules of self-protection are observed. Gloves and a respirator should be worn. If necessary, it is recommended to limit contact with fish waste products. Especially children should be protected, since their allergic symptoms develop very quickly due to the immaturity of the immune system.

Aquarium care rules for allergies

When an aquarium allergy occurs, special care is required. As a rule, with high humidity, fungal spores and mold are present, including on the walls of the aquarium. This negatively affects human health and especially children.

  1. It is recommended to place small stones instead of sand at the bottom of the aquarium, which can be easily removed and processed by boiling. This treatment will remove pathogenic microorganisms present on them.
  2. In addition, there may be deposits on the bottom of the container that rise during aeration. To neutralize this process, it is recommended to wash the aquarium and clean its filters at least once every 10 days. Only in this case will the water remain clean. There are special preparations available to make the cleaning process easier and at the same time to be the safest, especially for babies.
  3. Most commonly, a disinfected solution is used to rinse out aquarium care items. As an aid, a special magnetic scraper is used, which makes the cleaning procedure effective.

After following all the recommendations for cleaning and replacing the food for the fish, the allergy to fish will most likely disappear on its own. In the event that the symptoms of the disease do not disappear for a long time, causing discomfort, it is necessary to contact a medical institution for drug therapy.

Allergic disease treatment

First of all, it is necessary to identify the allergen and stop contact with it.

  • Further, antihistamines are prescribed, which effectively relieve allergic manifestations. Recently, drugs of the second and third generation, which have minimal side effects, have been increasingly used. These include Claritin, Zyrtec, Erius, Tsetrin, Telfast, etc.
  • in case of a complicated course, the use of hormonal drugs for external use is shown (Elokom, Advantan, Fenkarol). It is important to take into account that these drugs have a strong effect, therefore, their use in children is not desirable;
  • enterosorbents (Polysorb, Enterosgel) have a positive effect. They actively remove allergens from the body, ensuring the efficient functioning of the gastrointestinal tract;
  • very often the doctor prescribes a course of hyposensitization to reduce the threshold of sensitivity to the allergen. Small doses of allergens are administered to the patient, causing the body to produce antibodies. This procedure can be performed at the clinic. The duration of the course depends on the severity of the patient’s condition;
  • it is recommended to visit an immunologist who will assess the state of the immune system and, if necessary, prescribe immunomodulators;
  • in addition, it is important to regularly perform vitamin prophylaxis. Especially in the autumn and spring, since at this time the body is most weakened and prone to the development of infectious diseases and allergies.


An allergic reaction to aquarium fish is a common type of allergy that involves limiting contact with food and water from the aquarium.

  1. In the event that the patient suffers from bronchial diseases, you should protect your body as much as possible from the penetration of harmful substances. A peak flow meter has a good effect. This device is intended for individual use and is capable of measuring the peak expiratory flow rate. This allows you to control the state of the body.
  2. It is necessary to use different types of feed. In this case, the allergen is detected faster, which allows it to be neutralized. It is safest to feed pets with mosquito larvae, they rarely provoke an allergic attack. Only hypoallergenic fish food should be purchased.
  3. In no case should you put the aquarium in the room where the child sleeps. Especially if the baby is genetically predisposed to allergic diseases. It is best to set up the aquarium in a spacious, well-ventilated, light room to avoid mold and mildew. In addition, timely cleaning of the aquarium is recommended.

However, you should not permanently abandon the maintenance of fish with a mild degree of illness. Subject to all conditions of detention, you can avoid negative manifestations and enjoy your beloved pets, watching their life.
