So my little platy, Bob got fin rot a couple weeks back. I put her in a quarantine tank and treated her with Jungle LifeGuard. After about a week, she was all cleared up, so I put her back in the main tank. She was fine for about a week, and all today, but all of a sudden there are white blotches on her fins again after about an hour or so of me being gone today! What do I do? I put her in quarantine again and put in another dose of LifeGuard, but I'm at my wit's end on how to treat this thing. it keeps coming back!
The tank is a 10 gallon and tankmates include a male and female platy and 2 white skirt Tetras. There is a heater and filter also. Tank temp is about 76 degrees F. All the other fish are fine. What to do???
