Alright, so here's what the site says about black spots:

Black Spots


Black spots in goldfish, koi , and other coldwater fish often occur as a result of ammonia surges in the water. The black spots can appear on the side or back of your fish. Frequent partial water changes will help to correct this condition and the color on the goldfish should return to normal within a few weeks
 
I strongly suggest you go to your local petstore and buy a pH kit, a ammonia kit, and a nitrate/nitrite kit, or a master kit containing all of these. the master kit, from what ive heard, runs for about 20$.

If you do not correct this, your fish will die. But, as of right now, if you act quickly, you can save him. Smiley

Just change the water to keep the ammonia down, which is the reason. And do as Katarine said and get yourself a test kit. You'll need that now as your tank is cycling. And no, it won't come back once your tank has cycled. Or as long as you keep the ammonia levels low by the small and frequent water changes (around 10% several times a week.) It'll be fine (:

I guess... so change the water every second day at the very least. But if the spots are getting worse, I think you might have to change it every day instead. And remember, not too much! That would disturb the cycle and it would take longer.
It could also help feeding them a bit less during this time.

What would you use the salt for? And no, it won't hurt any fish as long as you don't overdose it.

Salt can be used for treating various diseases (: Like parasites and some bacterial and fungal infections. It can also be used in really weak concentration for preventive treatment. It's also quite useful in case you'd happen to get high nitrite levels (will come after the ammonia) a bit paradoxal since it slows down the working process of the bacteria that break it down.
It's actually a little bit stressful for the fish with any changes in their water, so unless you really need to use the salt, you should rather leave it be. And especially if your fish aren't showing any raised scales or wounds by those black spots, you don't need to use any salt (:

Oh nononononononono I'm not so smart sometimes when it comes to fish!!!! Smiley Please don't assume I'm a fish expert or something (truth be told i've only just started learning about fish myself!!!) ANYWAY ick is (I THINK) a parasite, but i may be wrong. It could be a bacterial infection. I'm not sure. Actually it might be a bacterial infection. Easily treated with meds and water changes. theres also white spots that appear during spawning.

Ich or "white spot" (Ichthyophthirius, lol, I found the latin name for you too! Cheesy) is a parasite indeed. It's a kind of worm that attaches itself under the skin of the fish, and gets the nutrition out of the fish's body. The white spots you see is actually the fish's skin that stretches over the bug. It's a kind of reaction of the immune system C: But sometimes, depending on temperature in the water the white spots may not be visible, but you could still find lots of these parasites if you'd look at a microscope! So other symptoms of this disease may be lethargy, clamped fins, isolation behavior, difficulties with breathing, and a reddish hue in the skin.

The best treatment option to this is to add salt at a 0.3% solution to the water to make sure you kill all the free swimming organisms. Keep the salt in the system for at least 14 days to be sure you eliminate every last one of 'em! It's also important that the water parameters are as perfect as possible. Sometimes increasing the temperature of the tank might speed up the process (:
It's also good to feed your fish with medicated food containing malachite green (there's one by Tetra Products) as long as your fish will eat, because this should take care of the parasites that are already attached to the fish (:

Hope that helped! Cheesy

a few years ago i won three goldfish from the fair,  i noticed they had black patches on them. soon after one  died. i started worrying about the other two, too. what i did to prevent the death of the other two was switch thier food to wardleys fish flakes. imedeately after i did i noticed a dramatic change in ntheir behavior, and their black patches whent away. ive had the other two for two, almost three years now. recently i got three more goldfish, one of which had black patches on it, also. now that i have introduced that other one to my tank, its black spots disappeared.

Black marks showing up on a goldfish may indicate a water quality problem.  Check your parameters first.
How big is your tank by the way?  Bullying can come from too many fish in too small living quarters.
Your fish need at least 10 gallons per 1 fish!

hi i had a quick question i got one of my fish at the fair and i got a starter tank which was under 5 galons. well i got a new fish while i was running my new tank which is 10 gallons through the 24 hour process. i started hearing thuds coming from the tank and i think it was becasue there were 2 fish in a small tank well when i finally put them in the new tank they dont fight any more but my common goldfish now has black patches only around its head and i thought first it was ammonia burns so i got my water tested and it was fine and everything was fine. while i was reading all the previous post i saw someone mention mella-somthing migration(sorry i couldnt remember the name) and i was reading about that the spots are similar to brusies on people and that the fish is healing. my questions are will the spots eventually go away, coould the food i am feeding them cause it, cause i just started a new brand its the tetra gold fish flakes. the info for the whole fish setup is i have a 10 gallon tank with a common goldfish and a ryukin goldfish with bubble stone and a filter. also what exactly is the 6 week cycle process i kept on reading what exactly does that do with the ammonia nitrate and nitrite??? Huh

AJ:: Melanophore migration it was (: And it's a process where the goldfish's skin changes color due to disease or healing of wounds, like you said, a kind of bruise! It can also happen because of water quality problems or simply stress.

Now, 10 gallons is the minimum for one goldfish, so as soon as these fellas grow you should really think about getting a 20-30 gallon for them to share. Another thing is that a common goldfish is much more boisterous than the egg shaped ryukin, which might lead to the common fish bullying the ryukin. So it's rather advisable to keep egg shaped, fancy goldfish only with fish of the same body shape.
I don't think the food would be causing the "bruises" to stay, but it might be that there is still a problem with these two fish together meaning that one of them doesn't get the time it needs to heal. And I don't think that they will be able to get along in the future either.
If you're certain that the water quality is good, then the spots are probably there as a healing process. If this is the case you need to observe the fish in question, if he's swimming alright, eating well, if he's active and whether the fins are clear and erect.
In case the black areas are raised or depressed your fish might have a bacterial infection, skin tumors or parasites.
So just keep an eye on your fish and see how he's doing! (: But he might just need some time alone in peace.

The cycling process means the time it takes for the beneficial bacteria in the filter and gravel to establish. They do so gradually, as the bacteria that break down ammonia and turn it into nitrites are the ones to appear first. Next are bacteria that change nitrites into nitrates and finally the cycle should be finished. You keep the parameters under control by changing the water often but in small amounts until the final bacteria are established. Then you can keep the nitrates on low levels by doing weekly water changes and by avoiding overfeeding or overstocking the tank.

He's not supposed  to be black on the fins and gills? If they recently appeared you should test the water for ammonia at least, and for nitrite, nitrates and possibly pH.
If the water quality is good, you should look closely at your fish for a few days, if he's acting healthy, if he's eating well and if any scales happen to raise or if he developes wounds on the skin.
About the white spots on the fins, I think you'll find the problem if you test the water. But I would only advice you to do the same here, observe your fish and see if the spots spread or if they disappear.

In both cases, if the water quality is bad, you should change the water immediately and add water conditioner that gets rid of chlorine and chloramines, and you could also add some bio filter booster. If the problem was ammonia, your tank is probably not cycled, so you should test for ammonia regularly and change the water everytime it's on dangerous levels. About 10% every other day.

Hello,
our goldfish is 3 years old and so far she has never been suffering any illness. Only lately she developed some black and white spots on the top of her head. First, the white spot appeared on her head, then after few days, it became dark, actually black. It has been growing bigger, but only on the top of head, nowhere else on the body. The body looks good.
At the beginning when it started, she was swimming sometimes very nervous and fast, sometimes scraching herself or suddenly jumping.
Last few days she calmed down and looks very tired and is swimming rather slowly.
We are worryng about our fishy. Please can anyone help.
Just need to add, we put some sea salt last week and it seemed to help for few days, but only few days, and then she started getting worse again.

Hi Fishka,

most times black spots indicate spikes of ammonia. They are burns.

Did you check the water parameters? Ammonia, Nitrite, Nitrate? pH?
Do regular waterchanges, feed fish less, provide best filtration and aeration ( airstone or airhose )
Keep track of your water chemistry with regular testing.

Can you post some pics?

All the best for your fishie

If there is Ammonia present in your tank water you should get Ammolock or zeolithe. And keep doing daily waterchanges, about 15-20%.

Do you have real or fake plants?

I would treat for a bacterial infection asap!
You can try Melafix but I would also treat with an oral antibiotic fish food.  Feed only the medicated food and nothing else for 5-7 days at least!
It could be that he bumped himself on something and the wound became infected.
Can you post any pictures for us to see?

Dear All,
Thank you for your reply and advice, yes, i have a picture, which was taken about 10 days ago. The black spot developed since then. It is bigger and actually it looks like there are more spots on the head, not just one anymore.
The aquarium is really big and we had only 2 fish in it, so they had really comfortable conditions. Suddenly one of them died about 3 weeks ago! The other one since then started getting ill. Since then we cleaned the aquarium very well and removed everything from there (we used to keep there small stones from the beginning). Now the aquarium is empty, so no plants, nothing, only the fish.
Here is the picture. As you can see on the picture, her mouth was also black, but it recovered since adding sea salt into the aquarium. Unfortunately, only the mouth recovered, and the spots on the head are growing rapidly.
thank you for your help.
