Not sure what’s wrong with my fish. Got this fish about 3 years ago. Always been fine, in a small tank. Moved him in to a 50 gallon tank, and randomly( few months in ) grows a big ball on his head looks weird looks like 50 small little bubbles. Not sure what’s wrong I feed him pebbles and used to feed him flakes I change/clean tank every few ( 2-3 ) months ( water always looks good ) can anyone help me out? Not sure if he’s in danger or pain. ( I tried to link a picture but didn’t let me)

@trondhansen honestly. I’m not even sure. I had just used water from my house. Maybe that’s the issue he used to have clean water like those water things that fill up ur gallons, clean water. Then I randomly switched him to water from well water, but the well water is in good condition, maybe he wasn’t used to it. I was using a filter for about a month but it randomly stopped working so I never cared to fix it or get a new one. I’m not the best owner cause I’m not that informed on sertian things. But I always make sure to my fishes water is clean and feed him– SpliqbtwFeb 4 at 6:32

Your fish is inbred
From the description you're giving, I suspect your fish is a Ranchu goldfish, a breed of goldfish known for it's bumpy head produced by extensive selective breeding.
I believe the specific term is lymphosystist, a genetic disorder characterized by an extremely lumpy head, present in Ranchu breeds.
How do you get lymphosystist? your family tree must be a straight line, or, in other words, inbred as hell.
It may affect your fish's ability to breathe and may make him more susceptible to infections

only vague memory, but from YouTuber AVNJ, an Ichthyologist from New jersey + random fish website rabbit holes, I'm sorry if this information is not valid enough Feb 7 at 19:54
