HOME AQUARIUM

THE REBATTER
Fungi Achilla, Aphanomyces, Saprolegnia. Depending on the conditions, the color of the fungus can be white and slightly yellow. They have branching and unbranched filamentary hyphae, lacking partitions, the thickness of which reaches 75 microns. The hyphae are surrounded by a shell and are filled with protoplasm, which contains a large number of nuclei. The terminal part of the hypha is broad and forms shells with zoospores. When the spores mature, the shell is broken, and zoospores are ejected into the external environment. These fungi can reproduce and sexually.

SYMPTOMS AND PATHOGENESIS
The disease develops when the content of fish in too cold water. There is a defeat of the skin, fins, gills, caviar (primarily unfertilized). As a rule, fungi act together with pathogens of other infectious and invasive diseases. They are constantly present in the aquarium water, and as soon as the fish is weakened or get mechanical damage, they parasitize on it. Initially, the fungal mycelium kills epithelial cells, and then penetrates deeper into the connective tissue, muscles and even internal organs, which the fungus gradually necrosis. On the skin, fins, eyes and gills of the diseased fish, thin dirty white threads appear which, rapidly growing, form a cotton-like plaque in a few days. Fins are shortened, glued and destroyed, can fall off. The fish refuses to feed, becomes sluggish and sedentary. Severe infection leads to the destruction of tissues and muscles. If you do not take measures, the fish dies. Often the fungus falls on the spawned eggs, and the development of the fungus begins with dead, unfertilized eggs, but with a significant development of the mycelium, it also passes to the developing caviar, causing its death.

DIAGNOSIS
The disease is diagnosed on the basis of clinical and pathoanatomical signs of the disease.

PATHOLOGYANATOMIC CHANGES
Hyphae fungus, growing, form a cotton-like plaque on the body, gills, in the mouth and even in the nose, and they penetrate into the body and destroy its muscles and internal organs.

TREATMENT
The aquarium with sick fish is disinfected with 3 - 5% solution of potassium permanganate. Sick fish are transplanted into clean "old" water, after removing the plaque on the body and treating the ulcers with cotton wool soaked in a solution of penicillin (500,000 units per 1 cubic centimeter of novocaine).
Preparations for entering into aquarium water:

• 500,000 units of ED of bicillin-5 per 100 liters of water, apply at night 6 - 7 days in a row at a water temperature of 24-26 degrees;
• 200 - 250 mg of sulfonomethoxin per 1 liter of water.

• 1 mg of collargol for 10 liters of water, aging for 20 minutes;
• 500 g of table salt per 10 liters of water, aging for 5 minutes;
• 500 mg of methylene blue per 10 liters of water, aging for 12 hours;
• 50 mg of malachite green per 10 liters of water, soak for 1 hour.

You can also carry out ozonization of the aquarium (with a volume of 50 liters - 25 - 30 minutes, 100 liters - 40 - 50 minutes).
Preparations for the treatment of caviar:

• 0.1 g of atebrine per 15 liters of water;
• 500,000 units of sperm per 100 liters of water.

PREVENTION AND RECOMMENDATIONS
It is necessary to constantly observe the optimum temperature regime, cleanliness, and density of planting. Pisces should be fed a variety and full-value feed. Producers are not recommended to feed a pipeman. It is recommended that 1 drop per 10 liters of water of a 5% iodine solution be introduced into spawning grounds. This prevents the defeat of fertilized eggs with fungi.
