Hello! I treated my fish 3 months ago for parasite infection. After treatment, poor fishy developed rectum prolapse. I treated with Epsom salt for 5 days / 15 mins. It worked well.
However, recently my fish underwent another round of parasite treatment and became sick again. There is an abnormal bulge on one side of belly, it is always sitting at the bottom of the tank and have a weird gait.
I've started epsom salt treatment level 2, 1tbsp per 2 gallons of water. Fish is swimming better and more reactive and does not stay at the bottom of the tank but the bulge is not going away.
Is there anything else I need to do? Should I be concerned?
