What causes, and what is the white spot on my Oranda Goldfish hood?

I set my tank up on Saturday evening, I added two Oranda Goldfish on Monday evening, On Wednesday morning one of them had a white spot on its hood about the diameter of its eye, and on Wednesday evening the white spot as fallen off and there is a slight depression where it was, but no other white spot or visible distress in either fish. Both swim fine and eat normally. Ammonia is well below alarm levels, Ph level is around 8.0 to 8.5. anyone have any clue what it was and what i can do if i see another white spot?

Update:

i have two filters on my 55 gal. a fluval 405 canister and a penguin biowheel 350, and i added a bottle(per instructions) of safe start with biospira. so should have started my bacteria near imediatley plus i added some ammonia on night one to feed the bac and quick start the cycle, i'm pretty sure my bio wheels changed color from near white to light gray by 32 hrs after i added the safe start. i did a 5% water change on Tuesday night(and added the proper amount of de-chlorinator). I know thats not a proper best case scenario cycle but should've been better than a strait fish add. i'm super proud of my filtration and i plan on adding one fish a week till i have 5 fish. then maybe a few months later i may add 2 more 1 week apart from each other. with the amount of filtration i have and bacteria that will be present to rid my tank of ammonia and waste.

    you didn't cycle your tank... be prepared for extra water changes. the only ammonia below "alarm levels" is ZERO, but try to keep it below 0.25ppm while cycling, same with nitrite.

    I find that goldies with wens randomly get these. I've never had one so large though, usually what I've seen is a tiny white dot.

    I'd just keep an eye on it to make sure it doesn't become infected.

    --------

    you should NEVER add pure ammonia to a tank unless you're fully cycling it.

    most bacteria products are dead and useless so they rarely work.

    I would highly recommend NOT adding anymore fish for at least a month until your cycle is completed and the tank is stable. also, any more than 4-5 would be overstocking. yes you have good filtration, but these fish grow 6" to 10" and more than 4-5 would be way too much.

    the amount filtration you have will rid your tank of ammonia, and even nitrite... but it will NOT remove nitrate. I certainly hope you realize your tank will require weekly 25% water changes just like any other tank.
