My fish have white and red spots on them and they are only active when I feed them. They are black moor goldfish and I don't know what's wrong. I think they are sick. What should I do???

It sounds like your fish have Protozoa (Skin Parasites). Quarantine any fish that show signs of the disease. Treat water with Formalin, Malachite Green, Acriflavine or copper sulfate.

Test water quality frequently; conduct periodic water changes; ensure good aeration and filtration of the aquarium water.

Water quality is very important to all fish, but particularly goldfish as they are very messy fish. You should also make sure that your aquarium is large enough, goldfish should have 10 but preferably 20 gal for the first fish and 10 gal for each additional fish. Smaller tanks are more difficult to keep clean due to the amount of waste that goldies produce. For my goldies I always do a 50% water change weekly preceeded by a water test so that I can keep tabs on their water quality. Clean fresh water is very important, particularly for a sick fish.
