Goldfish Disease Identification Possible Tumors



I did something exceedingly rare today because we had some rare weather. The sun was actually out today!  Finally.

My original intent was just to replace the netting over the top of my pond. That turned into, well why not clean the pond. Five hours later I called it a day.

Someone asked about an old post I did on Goldfish Diseases and if the disease was ever identified (it wasn’t). I responded to one of the comments saying this happens every year to a couple of my fancy goldfish. They do eventually die from whatever this is.

Below is my pond with most of the water drained.

These next 2 pictures are of one of the fancy goldfish that I captured to take a picture of. Those lumps on its body are consistent with what every sick goldfish has.  I’m not sure how many goldfish I have at this point, but I’m talking about perhaps 2 fish per year have this problem, always goldfish, never koi.

Does anyone have any idea what this disease is? I saw references to a fungal infection, but I don’t think that’s it. I’m suspecting tumors, and according to this site  this is exactly what it appears to be.  There is no known treatment for tumors, and although it does suggest you can cut off the growths, with my luck I’d try that and have a dead fish in my hand.

Maybe species of goldfish and not disease?January 17, 2015 – 7:34 am

inlikeflint - I’m having the same problem with my fan tails. I am removing them and euthanizing them to solve the problem… but I keep having goldfish with tumors pop up.May 31, 2016 – 8:18 pm

texdr - I had them each and every year and I have no idea why. Only the goldfish, never the koi. The numbers would actually balance out as a couple would die, then I’d find two new ones the following year. I have no idea how to get rid of it or prevent itMay 31, 2016 – 8:51 pm
