Fin Rot In Fish (fin Rot)

Fin rot (fin rot) is a very common disease among aquarium fish, caused by the bacillus Pseudomonas. The primary cause of this disease is poor water conditions, stress due to aggression from other fish or any activities in the aquarium, which weakens the fish's immune system and it cannot fight disease-causing bacteria. Sometimes the bites of other fish lead to rotting of the fins.

Signs: the surface of the fins of the fish begins to decrease, their edge becomes uneven, torn, the edges become semi-transparent or white. If you notice any of these signs, check the condition of the aquarium water.

Reason: Fin rot is caused by bacteria that live in any aquarium. They are usually harmless, but if the fish has a weakened immune system, then it cannot resist the disease.

Treatment: Fin rot sometimes heals on its own if water quality improves. So, there are cases when rotting plants in the aquarium have led to the disease of fish. Removing the plants, changing the water three times at 20% and rinsing the filter thoroughly helped improve the water quality, causing the fish to heal themselves and their fins to regain their shape. Fin rot can be easily cured by removing the stressor. Salt baths also give good results.

For those fish that like salt water, 1 tablespoon of salt is enough for 5 liters of water, for most fish 3 teaspoons per 5 liters, and for sensitive fish - 2 teaspoons per 5 liters. Bath time - 30 minutes. For especially advanced cases, almost all types of antibiotics are effective.

Please note that you cannot run this like any other disease. If the rot of the fins reaches the body of the fish, it will be fatal for it.
