Freshwater Fish Columnaris is a serious problem. Columnaris is a common disease affecting freshwater fish. It’s caused by the bacteria Flavobacterium columnare and can have serious consequences if left untreated. Symptoms include white cottony patches on the skin and fins, frayed fins, red streaks along the body, open sores, loss of appetite, lethargy, and even death in extreme cases. Columnaris is highly contagious and can spread quickly among fish in a tank.
The best way to prevent Columnaris is to keep your tank water clean and properly maintained. Regular water changes and filtration are important, as well as maintaining a consistent pH, temperature, and nitrate levels. It’s important to quarantine any new fish before introducing them to the tank, because they could be carrying Columnaris or other diseases. If Columnaris does occur, you must act quickly to treat it and prevent it from spreading to other fish in the tank. Antibiotics such as Maracyn and Maracyn Two are commonly used to treat Columnaris, as well as salt baths or potassium permanganate dips.
