Your fish will need to be sedated, and a small scraping of the lesion will need to be obtained for a biopsy. The most reliable way to accurately diagnose cotton wool disease is to pay a visit to your local veterinarian. Diagnosis Of Cotton Wool Disease In Freshwater Fish We know you’re excited to introduce your new fish to its home, but be patient! Quarantining new fish can save you a lot of heartache down the line. Fish from pet stores are typically kept in large groups, where the risk of cross-infection is likely. Given the risk of a widespread infection, the best thing to do is to isolate all sick fish to protect the other occupants of the tank.Īnother common mistake is adding new arrivals to your main tank without quarantining them prior. Certain strains are more infectious and deadly than others.
Contact With Infected FishĬolumnaris disease is highly infectious and can spread between fish. To lower the concentration of organic waste in your tank, perform frequent water changes and remove solid organic waste, such as fish droppings or uneaten food. Fish that are kept in poorly maintained tanks are more likely to contract illnesses, which in turn increases the odds of a secondary columnaris infection.įurthermore, columnaris bacteria can be found in areas with a high density of organic waste. Subpar water quality creates conditions that allow columnaris bacteria to thrive while putting the health of your fish at risk. Fish that have been selectively bred for multiple generations, such as neon tetras also tend to have immune systems that are lacking. An existing illness causes the fish’s immune system to be compromised, increasing the likelihood of secondary infections such as those caused by the columnaris bacteria.įish that are malnourished, or kept in less-than-ideal water conditions may also lack the strength and immunity to fend off cotton wool disease. However, a few factors may cause these bacteria to infect a host fish with columnaris disease.įish that are already weakened by another illness or infection are more likely to get cotton wool disease. Here’s one thing that needs to be made clear about cotton wool disease – it is caused by a type of bacteria that already exists in every tank! Under most circumstances, these bacteria are harmless. Causes Of Cotton Wool Disease In Freshwater Fish However, these are symptoms that are common in many aquarium diseases and should be assessed against other indicators of the illness. Other behavioral changes one might observe include lethargy, loss of appetite, and difficulty in swimming. Scratching is yet another indicator – fish may swim against objects to alleviate the itching caused by columnaris. Some fish may move their gills quicker or gasp for air at the surface of the tank in an attempt to breathe. The key sign to look out for is breathing difficulties.
This causes several behavioral changes as the disease progresses. However, slow-acting strains kill fish by gradually affecting their gill tissues. Quick-acting strains of columnaris disease typically kill their victims in 48 hours, meaning that fish owners might not get a chance to observe behavioral changes.
