I have just lost 2 male lyretail mollies, and now my female American flagfish has a strange whiteish lump under its scales/skin. Also, it’s eyes seem to be bulging a bit.
You can see the whiteish lump thing just above and slightly to the right of the black spot on her side in pictures 1 and 3. Right now it is about the size of 2 or 3 of her scales.
Water stuff: Ammonia and nitrite: 0 ppm, nitrate: 10 ppm, pH: 7.5, temp: 77 degrees Fahrenheit, tank size: 20 gallon long
I know this isn’t the right thread for this, but yesterday when I posted this in the fish disease thread only one person answered, but they didn’t know what it was.
