Hi
A few days ago a lump started developing on my goldfish's side and he was scratching against the glass. I added aquarium salt to his tank and he stopped scratching but the lump developed into a white spot. It's the only white spot on his body and it's bigger than a sugar grain so I don't think it's white spot.
My goldfish is the only fish the tank. He's in an 80 litre tank and there are no plants in the tank. He's around 8cm long and he's 1.5 years old. The filter is a carbon sponge filter and the tank is 72×36×36cm. Last time I did a water change was 4 days ago. There's no gravel in his tank. The tank was set up a year ago. I haven't added anything new to the tank recently.
I really need to figure out what this lump/spot is before it really starts to do some damage.
