So I have been dealing with this now for a few weeks. My guppies keep getting these lumps on their mouths, sides and near the tail. They look like round sacs that protrude from the fish but they are also in the fish near the tail. What am I dealing with? I have been treating them in my hospital tank for about 8 days now with Paraclense and Maracyn but nothing seems to be working. I haven't lost any due to this but really want to know what I'm dealing with so I can get them better.
