Fish living in the confined space of a home aquarium are unfortunately often prone to diseases, including infectious ones. This is due to:
- large accumulation of individuals per unit volume;
- insufficient amount of oxygen in the water;
- high, not physiological, indicators of acidity of water and its hardness;
- non-observance of elementary rules of sanitary and hygienic nature.
An example of diseases with such risk factors is fin rot – a disease that is bacterial in nature and is characterized by a high indicator of contagiousness.
Not to notice such a disease is impossible. From the earliest terms, practically from the moment of infection, changes in the condition of the skin, fins, color and transparency of the eyes are observed. In addition, the behavior of fish is changing, they become drooping, moving slowly and doomed.
Sometimes refuse to eat.
At the ends of the fins (especially the chest) and the tail, the blue and white band at first becomes noticeable, which gradually collapses. This visually changes the shape of the fin base, making them look like bitten or wounded.
Such fins, especially in fish with their considerable size, lose their protruding characteristics, fall down, look glued and prevent the fish from making swimming movements.
Gradually, the fins may collapse to the very base. In this case, their recovery becomes impossible.
In addition to the fins, the total upper trunk of the trunk is subject to change. The scales can be protruded to the sides, in some places to collapse, forming a semblance of ulcerative lesions, often even with bloody discharges.
All skin may be covered with mucus with a cloudy shade and uneven distribution over the surface. Often in parallel develops gill rot, which subsequently does not fully absorb oxygen from water.
The fastest signs of the disease develop in young individuals. Considering that their own immunity forces are not enough for them, the probability of death is high.
Older fish, in case of timely start of treatment, have a chance of recovery.

In order to determine how to treat fin rot and diseases of both gills, it is necessary to know the risk factors of its development and the main sources of infection.
Etiological factors are bacteria from the genus of aeromonads (gram-negative microorganisms living in warm dirty water), vibrios (curved in the form of a comma bacteria with one or two flagella to increase their mobility) and pseudomonads (pathogenic organisms that cause rotten processes of all living things).
The pathogens of these groups can get into the aquarium in different ways:
- when moving sick fish;
- use of water or plants from polluted natural reservoirs;
- use of natural feeds for feeding fish that do not guarantee their quality.
The factors contributing to the development of the process are non-compliance with water standards for one individual, poor aeration and filtration, untimely cleaning of the aquarium and water replacement, accumulation of uneaten food and its rotting, inconsistency of water parameters with the requirements of the plants used, violation of the recommended temperature.
Fin rot is considered a treatable disease, as well as gill rot. However, in order to cure it is necessary to carry out activities in parallel on the fish and the aquatic environment.
The ideal option is to treat living beings in a separate aquarium. The main place to stay at this time you need to wash as much as possible, disinfect, treat with antiseptic and plant healthy plants.
Soil and design elements should be boiled and washed away in any hard-to-reach places.
Fin rot in fish is well treated with solutions of any antibiotic. You can use chloramphenicol, erythromycin, tetracycline, ampicillin. Tablets purchased at any pharmacy must be crushed into powder and diluted thoroughly in a liter of water (0.5 g per 10 l of water).
Pour into the aquarium and stand for 8-10 hours. It is recommended that after the expiration of the exposure, change one-third of the water to fresh and repeat this sequence 5-6 times.
Today, it is possible to purchase broad-spectrum antibiotics that have a bactericidal effect on virtually any causative agent of putrefactive processes (bicillin, biseptol, amoxicillin, meropine and others). The choice between them is in price and availability.
The calculation of the amount of the drug is based on their content of active units in the filling volume.
If it is not possible to plant fish or there is no desire to resort to the use of antibiotics, you can try to remove the fin rot after treatment with brilliant green (green) or methylene blue (blue). For the treatment of fish, it is necessary to prepare a solution of 1-2 drops per 5 liters of water.
To sustain the sick individual in such a composition for 10-15 minutes. Repeat the procedure 5-6 times.
There is also a method of treating fish with streptocide. This method is more gentle for fish, but the amount of the drug for the same effect is needed much more.
The recommended concentration is 1.5 g per 5 liters of water.
The most successful way to cure the disease is in neons, mollies, swordtails, labyrinth rocks, petsillium, barbs.
Replant fish in a common aquarium is possible only with full treatment. Sick fish, in order to avoid subsequent re-infections, should be kept separately until the clinical manifestations disappear completely and the lifestyle is normalized.
During treatment should be approached differentially to nutrition. During this period, you need to feed less and use nutrient-enriched feed.
Leftovers need to be collected immediately and not allowed to accumulate at the bottom.
Any disease is easier to prevent than to treat it. Therefore, prevention measures should be high priority. To prevent the spread of infection in the aquarium can be one of three ways:
- completely exclude the ingress of infectious onset (only high-quality water, algae and healthy living creatures);
- eliminate the factors of transmission (observance of sanitary and hygienic rules of care for the aquarium, optimum settlement, necessary additional water treatment);
- strengthen the fish’s own immunity (balanced diet, healthy living conditions).
Being engaged in the aquarium business, it is worth remembering: only a water house with vigorous and healthy inhabitants can have a beautiful appearance. Therefore, timely recognition of trouble – the key to success and a guaranteed result.
