This is about to happen for the third time in the last three to four weeks to one of my fish. I forgot what kind, I have had him for two years, Silver elongated body with orange fins, black near the tail, about 3 inches long.
This fish developed swelling on one side, as if something was growing under his skin, you could see it bulging; it literally burst on that side, some grayish matter fell out to the bottom of the tank. The gap was almost 1/2 an inch in diameter. By the next day it was nearly healed over. I thought maybe it was a cancer. It is about to happen again same spot in the next day or two. I added melafix to the water. I have no idea what this is and no one at my fish shop is familiar with it.
The fish remains active, and eats well.
