The causative agent of chylodonellosis is a parasite (ciliator Chilodonella cyprinis). The disease occurs most often in cool water, you can also bring it into the aquarium along with food - a tubule and bloodworm. Chylodonella rapidly multiply in water, the temperature of which is below 23 ° C. To infect all the fish in the aquarium, one to two days is enough. Despite the fact that the disease develops in cold water, increasing its temperature, after detecting the disease, is not an effective treatment.
Symptoms of the disease
The onset of chylodonellosis can be determined by several symptoms. The first thing you should pay attention to is the amount of feed eaten. A significant decrease in appetite is a sign of the onset of the disease. In addition, one can observe the contraction of the caudal fin, but it does not look disheveled. During the disease, areas of the skin are affected in the fish. Turbid whitish patches appear on the back or sides, closer to the fish’s head. Often this plaque can be seen only at a certain angle of incidence of light. The area of these spots may increase in size over time. It is also necessary to pay attention to the behavior of fish, which is characterized by lethargy. Fish swim in the aquarium at the very surface of the water. If the water in the aquarium begins to cloudy slightly (this is caused by the rapid multiplication of chylodonella), and there are no other reasons for this, this may also indicate the onset of chylodonellosis.
Salt baths are used to effectively treat chylodonellosis. To do this, fill a separate container with 2-3% saline. For its preparation, ordinary coarse salt and settled tap water (or water directly from the aquarium) are suitable. If the house does not have accurate weights, then approximately two teaspoons of salt per liter of water are used. In this solution you need to buy fish. The duration of bathing fish in saline should not exceed 15 minutes. It is necessary to carefully monitor the behavior of the fish. If they cannot go to the bottom of the tank and begin to be pushed to the surface of the water, the salt bath should be stopped immediately. If the disease of the fish is started, you can not use a strong solution. The salt content in the water in this case should not exceed more than 2%, otherwise the fish may not be able to withstand such bathing. For the full recovery of the fish, it is necessary to carry out 2-3 such procedures with an interval of several days. It should be noted that the temperature of the water for bathing fish should not be colder or warmer than the aquarium by more than 2 ° C. If the fish did not bathe in saline, treatment of chylodonellosis can be carried out using an antibiotic - levomycetin. To do this, add it to the aquarium water at the rate of 3.5 - 4 g per 100 liters of water. Repeat the procedure up to 2-3 times, add the antibiotic to the water every three days. During the treatment of fish, the water in the aquarium should be warm, not lower than 26-27 ° C.
