My pearl scale goldfish has a growth on its head. I believe it is a growth rather than a fungus or "ick" because it is not white and cottony, but is flesh-colored, and because it is concentrated in only one area. I think it began last October. It's getting steadily bigger and seems to be curving around and will soon start to poke my fish's eye. My fish is twelve years old. I have some pictures but I'm not sure how to post them, of if I can.
Can people perform surgery on goldfish to remove growths like this? I'd be very grateful for any advice you can give. Thank you so much
