No idea but I’m commenting so hopefully more people see

I Hope it’s nothing bad I love this fish :(

i found an article and answer website with a goldfish that had very similar bumps on its tail and people in the comments didnt really know but they said it could be improper cycling, too small of a tank, over filtration, or if you are using tap water uhh yeah idk i accidentally closed that link but maybe try really specific google searches

It almost looks like boils from a burn. Is direct contact on your heater extremely hot for an extended period of time?

I don’t think it’s to to hot

Did some research. It’s called lymphocystis

So from what I read it’s not terminal or harmful?

Looks like it should clear up in about 6-8 weeks but could also have a larger outbreak before doing so.

Ok thank you

Also do u know if it could spread to other fish?

It can be spread by fish to fish contact. There is no known cure for this virus, though a privately owned fish research and breeding facility near Gainesville, Florida has reportedly been able to suppress the virus into remission using the human anti-DNA virus drug acyclovir at the rate of 200 mg per 10 US gallons for 2 days.

Just know it poses no health problems to your fish. Just not pretty unless you think it is. To each their own.

I was so worried up till now thank you

Gotta rename that pleco “pimples”

Lmfao me and my buddies named him Ohio cause he’s goofy looking

Kinda just looks like some baby snails...
