My goldfish has a growth on it's side?

Question

I was feeding the fish this morning and I noticed that one of them has a growth on it's side. It looks like a tumor and it's kind of round, but doesn't seem to be affecting the fish at all.

It looks like it's been growing for a while and like I only just discovered it today as it can't get that big over night.

What could this be and how to I treat it?

Thanks.

Answer 1

go to your oet shop and get some stuff for growths

all you need to know is how much water is in the tank and you just add this soloution to the water

the growth should then clear up in no time
