Branchomycosis: symptoms, pictures, and treatment in an aquarium

Hello dear readers! We continue to study the aquarium ailments that may appear in our aquariums.

The hero of our article today is a fish disease called Branchomycosis, or gill rot. The causative agent of this sore are fungi that affect the gill apparatus.

Even considering that Branchomycosis is a rare disease and it occurs only in dirty aquariums in which the ecological environment is disturbed, these factors do not make it less infectious.

The most common reason for gill rot entering the aquarium is live food, namely daphnia and cyclop. The fungus successfully develops when the temperature of the water environment is 25-32 degrees, pH about 5.5-6.0.

Infection of fish with fungal disease occurs during respiration. Hyphae of the fungus enter the gills of the fish and are fixed there, and then germinate.

Freshwater aquarium fish, which are contained in unsatisfactory conditions, are most susceptible.

You should know that high temperature of water and excess organic compounds become a good incentive for the development of the disease. As the fungus grows in the gills of fish, they clog large and small blood vessels in the gills, which leads to the death of the affected gill areas.

In the future, these affected areas rot and decay due to exposure to pathogenic bacteria.

The symptoms of branhomikoza are similar to other diseases, such as fish tuberculosis, sanguineoses, dactylogyrosis and ichthyosporidiosis. But here there is one important nuance, gill rot can ruin 80% of the population of your aquarium during a week.

A clear symptom of gill rot is the appearance on the gills of fish dark red stripes and places of destruction on the gills. In the later stages of the disease, mosaic bright color and necrosis appear on the gill lobes.

This further leads to breathing difficulties and suffocation.

A sick fish stops eating and does not react to an external irritant, its reaction slows down significantly. In addition, you can see how infected fish are kept near the surface of the water or near the filter.

In some cases, diseased fish may hold near the ground or in the dark corners of the aquarium in an absolutely upright position. Also, the fish appear itchy, which they try to eliminate by scratching the elements of the aquarium decoration.

What can lead to occlusion of gill blood vessels? This leads to stagnation of blood and the gills become dark blue with a light touch. Gill lobes are also significantly reduced in size.

With a strong fungal infection, the fish can swim on their side and in this position they often die. If you still managed to cure your pets from this terrible disease, then the restoration of the gills after a lesion can take up to a year.

And even in case of successful treatment, the gill lobes are not fully restored and you can see damaged areas on them.

In the treatment of branhomikoza themselves well recommended therapeutic baths with fungicides. After establishing an accurate diagnosis, the aquarist must remove as much organic residue as possible from his aquarium: the waste of the inhabitants and all the uneaten food. After this, carefully wipe the soil and replace about 50% of the water with fresh.

Next turn on the intensive aeration of aquarium water.

In view of the fact that gill rot spreads very quickly through the aquarium, it is better to use medicinal solutions in a special quarantine. At this time, the aquarist must thoroughly process the main aquarium and all its accessories and equipment.

Therapeutic drugs used in the treatment of Branhomikoza:

  • Sera mycopur;
  • Phenoxyethanol;
  • Collargol;
  • Nystatin;
  • sea ​​salt;
  • Methylene Blue;
  • Acrimet;
  • Sera Omnipur;
  • Sera ectopur.
