My fish has cotton fungus & swollen belly. Should I use epsom salt?

Updated On September 23rd, 2025

Pet's info: Fish | Unknown - Fish | Female

Hi! Two days ago I adopted an injured blue gourami fish. It was injured 10 days ago. Some of the minor wounds healed before I got it, but one has a fungal infection (like white cotton). I have started to treat that with something called Furamor-p. This is supposed to also treat swollen abdomen, which I also see. Should I remove the fungus physically, or should I just let the meds work and hope for best? I have heard that epsom salt helps a swollen abdomen. Is this something you would recomend?

Physically removing the fungus may cause more stress. Allow the medication to work. Read the package directions carefully and remove the carbon insert from your filter, if necessary, during treatment. Epsom salt can help with fluid retention if that is the cause of the swollen abdomen. Other causes include swim bladder issues, intestinal parasites or constipation. An epsom salt bath would be preferred over treating the entire tank. Dissolve 1 tablespoon of epsom salt in one gallon of tank water. Remove the fish from the main tank and allow it to swim in the salt bath for 15-20 minutes before returning it to the main tank. Do this once daily.
