I'm not sure what kind of white spots you mean, since there are a few different parasites and infections that have these symptoms. But what I would do is to test the water, first of all. If there's anything wrong with your fish, it's 99% certain to be because of the water quality. So test the pH, ammonia, nitrite and nitrate and post the results, if you don't have a test kit for these parameters, you can either buy one, or bring a small cup of pond water to your pet shop and ask them to test it there. It's most important to deal with the reason why the fish are sick rather than simply treat the problem at hand, that way it's easier to prevent future disease.
After this is done, you should do a large water change, around 50-70% should be good! Now you should add some medical aquarium salt to your pond, take a small bucket with pond water and dissolve the proper dose salt there first. Otherwise the fish may be burned by the salt. Try keeping the salt solution constant for a week or two, meaning that you add a proper dosage for every water change. The salt should be dealing with most of the parasites and health issues of goldfish, so it's usually a good way to go You also have to test the water every day during the treatment to be sure that the water quality is as near perfect as it can be (pH=7-8, ammonia+nitrite=0, nitrates=<40ppm), and change the water anytime either of the parameters are off. Feed your fish nutritious food! A full belly is usually not a sick one when it comes to fish But don't overfeed! Give them lots of live foods, vegetables and some pellets or flakes to boot

I'm sure your fish will be just fine

thankyou, for your advice. I will do as you advised. I have been feeding the tetra gold fish food its the one with different pellets in, water shrimp ect. says its high in protein. also been feeding live food once per week.

hahahaha Nossie, not only in Goldfishies life, in ours too....

Hanna: Lol, meant to write it more like this: "...in goldfishes' lives too"

linda: Sounds alright there Can you test the other parameters too? Ammonia, nitrite and nitrate are important because these are downright toxic to fish in higher concentrations and will have an impact on their immune system. That's why it's very important to know whether it's dangerous to them or not. So please, test it as soon as possible I mentioned in my first post which levels are accepted!

Sounds really good! I bet your fish will be perfectly alright So glad that you care this much for them

Yes! Be sure to treat the fish until all signs of disease are gone, please That way you can be absolutely sure that they've recovered fully I'm so happy for you

Done them tests.  PH today was 7.5
Nitrite was 0.1
Nitrate was around 100

My pond is only about 2 months old and I do have plants. Thankyou for your help and advice again

Nitrate 100 ppm This is far too much. Do as Nossie said. Test again to make sure and do a huge waterchange with conditioned water though.

Nitrates ideally should be below 40, better 20 ppm

If the white spots are just on the gills, don't worry.  It means you have a healthy, virile boy.
