Ammonia burn is the most common reason for black spots on goldfish, especially those that have been in a tank for about 2-3 weeks but can occur in setups longer than that due to poor water quality and/or lack of regular weekly water changes (about 1/3 each week for a tank 20g or over - any container less than 20gal should have 1/3 changed every 4 days) or if more fish are added. Goldfish are messy eaters meaning they don't always consume everything you feed and they excrete a high amount of ammonia wastes - the combination of uneaten food and high ammonia will cause such high concentrations that is poisonous and will literally burn the gills and skin of the fish. regular water changes (of similar temperature) and a water conditioner such as Prime will heal the fish and maintain optimal water quality.
Fungal/parasitic black spots is not as common but not unheard of, esp from carps, minnows and other cold water fish that were housed or raised in ponds and/or with a large snail population.
Black spots on gold fishIf the black spots are standing up it is fungal. You need to treat for a fungal infection right away. Usually black spots are just an indicator your fish is recovering from an infection and they are signs of healing. Continue with your weekly 1/4 water change outs and don't forget to add aquarium salt. One heaping tablespoon per five gallons.If it appears fungal increase salinity to 0.3%.
