Hello dear readers! We continue our excursion into the section “Diseases of aquarium fish” and today on the agenda we have one of the most common diseases called Fin rot.
The main reasons for the appearance in the aquarium of this infectious disease are fish aggression, constant stress and dirty aquarium water.
Another aquarium fish sore transmitted through normal contact between healthy and sick fish. Such fish as labyrinths (gourami, lyalius, macropods), viviparids (patsilias, swordtails, mollies, guppies), scalars, barbs (cherry, denison, shubert, sharks), red and blue neons are most susceptible to fin rot disease.
As a rule, mass death can occur only in young animals, in adult fish there is a great chance to recover, but on condition that the aquarist makes a correct diagnosis and starts treating the pet in time.
Very often, fin rot becomes a secondary infection that accompanies systemic bacterial disease. And in this case, it is often accompanied by symptoms such as: ulcers on the body and abdominal distention.
The aquarist must know the difference between fin rot from a little-known alkaline disease. With alkaline disease, due to the high pH level, the fins of the fish “melt” along the edges and decrease in size.
If your fish have had decay, they can grow their fins, but the rate of recovery after the disease depends on the age of the fish, its maintenance conditions, the degree of damage and diet. Those fish whose fins have been completely destroyed, unfortunately cannot be treated.
In this case, they need to be rejected. If you caught the development of the disease at an early stage, then 90% that you cure your pets.
The causative agent of fin rot is the bacteria of the Vibrio group, Pseudomonas and Aeromonas. The disease quickly spreads around the aquarium and settles on the fins of the fish. The above pathogens are found in large quantities in natural waters, from where they enter our aquariums, along with poorly processed stones, snags and plants.
They are contained in large quantities in feed, aquatic plants and soil from a river or lake. In addition, pathogens can be transferred by aquarium fish that have not been quarantined and prevented.
Therefore, I would like to warn you once again – when you buy new fish, do not plant them immediately in the general aquarium, let them sit in quarantine for several weeks.
- Fin rot is a progressive infection in which the fins of fishes are destroyed extremely quickly;
- In young individuals, this is due to the disintegration of the pectoral and caudal fins. In older fish, this trend is not observed. The main difference between rot and alkaline sores – in the first case, the fins begin to break down from the edges and gradually move to the base. And at the crack, only the edges are destroyed and the fins are reduced in size;
- The first and most obvious symptom is the appearance of a bluish-white opacification on the fins, which is especially clearly visible at the edges. Infected fish on fins appear white-blue border, which will expand to cover the entire area fins. In young fish, this is especially noticeable, because the color of their fins is almost transparent;
- The appearance of spots and red stripes on fins is also another symptom. The appearance of such symptoms is due to clogging of blood vessels, which leads to the decomposition of the rays from the edges;
- The affected areas of the rays can become inflamed and separate from the base. If in adult fish this process is not so terrible, then in young animals the tail fins dissolve completely;
- At the base of the fried areas, white-colored ulcers appear, from which purulent fluid is released. If the fish is not treated, the infection will spill over to other areas of the body and then death occurs.
If the aquarist proceeded to the treatment of infection at an early stage, then problems should arise. First you have to make a 30 percent replacement of water for fresh. Next you need to increase the temperature of the water in the aquarium to the maximum possible value for your fish.
This is a very important step, because how far from all the fish will be able to survive the temperature increase. If you have such fish in your aquarium, fin rot rot is best treated in a special aquarium.
If the above actions have not improved the condition of the infected fish, then it is time to start the drug treatment.
The methods of drug treatment are as follows:
- Very well proven levomycetin. For 20 liters of water should be one tablet. To start, grind the medicine into a powder, pour it into a small container with water and dissolve it there. Then the mixture was poured into akvas. Since chloramphenicol is poorly soluble, you will have to be patient. Then every 3 days you replace about 30% of the water in the aquarium with fresh water and fill in the next portion of the treatment solution. This procedure must be repeated until your fish feel better;
- If you are treating sick fish in the general aquarium, then try streptotsid. The proportion is as follows: for every 10 liters of water, 1.5 grams of streptocide is necessary. Just as with chloramphenicol, the medicine needs to be dissolved in a small container, and then the resulting mixture is added to the aquarium. Unfortunately, streptocid also poorly soluble in water. It is possible to treat fin rot both in the general aquarium and in a separate container. Take a streptocide tablet and dissolve it in a 6 liter jar. The temperature of the therapeutic mixture should be 28 degrees. Hold the sick fish in this tank for half an hour and then send it to the general aquarium;
- Another good drug that does an excellent job with fin rot treatment is bicillin-5. As a rule, there are 1,500,000 bottles sold. To treat the fish you have to spend only 1/6 of a bottle, dissolving in 10 liters of water. The therapeutic mixture is poured into the tub, where sick fish are transplanted for half an hour. For treatment of rot you have to repeat this procedure for six days. For 6 days you just use up the entire bottle of medication;
- Another drug that can be used to cure fin rot is Biseptol-480. It can be bought at the pharmacy. Since the drug is sold in tablets, you have to grind it into powder. For 5 liters of water should be 1/8 pill. Lise Biseptol for a week and for each procedure you need to prepare a new solution. A prerequisite – the fish must always be in the drug mixture and it must be aerated;
- You will probably be surprised, but fin rot can be cured with common salt. Take 3 teaspoons of table salt and dissolve them in a five-liter container with water. Then put in a medical mixture of sick fish. Only you should take into account that such a concentration is not suitable for all fish, because all fish react differently to salt water. While the fish are treated in a separate container, the aquarium and decorations with the equipment are disinfected and boiled. Aquarium plants must be processed in a solution of bicillin-5.
Those fish that have a weaker immune system are most susceptible to the disease. Also negative conditions include poor conditions of detention. It is possible that the reasons may be combined.
Suppose a fish has damaged a fin in an aquarium, and the water in the jar is of poor quality. But do not think that because of the trivial damage to the fin, the fish will surely get rotten.
To reduce the likelihood of infection of fish with this infectious disease, you must properly feed your fish and provide them with good housing conditions.
