The most famous disease I heard of that goldfish get in the swim bladder infection. I am not so sure how people cure it, and the symptoms are when the goldfish is lying on the ground. Sometimes goldfish get parasites (worm thingys too) in their bodies, and it makes it harder for them to swim. One of my fish has constipation, and you can know this by noticing long strands of poo sticking out from their butts. and not falling off. The insides of boiled frozen peas help cure this.
Well the most common pathogenic threats to goldfish are probably bacterial infections and Ichthyophthirius multifiliis or more commonly referred to as freshwater "Ich" or "Ick". However the most common contributing cause for disease is probably poor water quality or insufficient housing / maintenance of goldfish.

The third most common pond goldfish would be the Shubunkin, the third for the common goldfish varieties would be the black moor(although this technically counts as "fancy"), and the third for the fancy goldfish would probably be the Celestial and the Ranchu.To make this data more clear I've organized it into a list:1.
