Goldfish Bumps

[LordOfTheFish]

In our outdoor pond we have two goldfish. Lately we have been noticing a few bumps on not one but both of our goldfish. What should we do? These are really pretty goldfish, and we definitely don't want to let them die. Thanks!

Do you have a picture of them?
What are your water stats?
Are the bumps white?
