Goldfish with black spots
« on: May 01, 2008, 10:56:44 AM »

I have a tank with two small goldfish in it.  I just noticed recently  that one of the goldfish has two black patches on it.  It sometimes swim with its face down.  Is the goldfish ok?

How do i get rid of the dark patches?

The goldfish probably  has ammonia burns as a result of  too  much ammonia in your tank. You should try checking the ammonia and nitrate level with a testing kit.

You should do this first.
Perform a 50 percent water change first off,then 10 percent every day for a week,keep testing the ammonia in the tank every two days with a test kit to see if the levels are coming down.
You could be over feeding your goldfish or not doing enough water changes. Goldfish tends to  produce a lot of waste which turns into ammonia in your tank in your case your fish have ammonia burns you must do a water change before your fish die.

It could possibly be something called melanophore migration.

I'm not sure if this sounds like your fish- if you don't do regular water changes, a high ammonia level, pH problem, or secondary infection could have brought this on if that's what it is. Goldfish tend to produce a lot of waste. Also make sure you are not overfeeding your goldfish.

The only way to reduce the ammonia is to dilute with a partial water change as a temporary fix. You will need to upgrade to a  larger container or tank to "fix" the problem long term.


Hope that helps! Good luck!

Hi lynn,

Sounds like your goldfish prob. has Ich or white spot disease.

"Ich is the name for the parasite Ichthyophthirius multifiliis and the disease which results from the parasitic infection. The parasite is able to kill large numbers of fish in a very short period of time, thus early treatment and diagnosis are necessary to help reduce fish losses and control Ich. As always , preventing the parasite from infecting the goldfish in the first place is, of course, the best method of avoiding goldfish mortalities."

Antibiotics, such tetracycline or chloramphenicol, and Malachite can be used to effectively to treat Ich.
You can find these drugs at stores Petco , petsmart , walmart , etc..  I know for sure Petco sells tetracycline and other antibiotics using the brand  Gel-Tek since i bought them there only a few weeks ago.


You can read more about Ich here: (Link is not visible to guests. Please register to view.)

The black spots could be bruises caused by rough handling but it could also be ammonia burn. You probably shouldn't of got the fish from a fair because it's very cruel and unhumane to do that to them, also, with the white spots, that's probably ich and you should get some good ich medicine and follow the instructions carefully.

No no no no!!!! If a goldfish has black patches and it freacken moves then its the parasite called Argulus or fish lice. The best way to get rid of them is by getting a tweaser and slowly without hurting the goldfish you grab the parasite and you throw him out. Theres medicine that takes care of these parasite but it takes too long t kill them and in the mean time your goldfish will get they're blood sucked out. Also, siphon the gravel cause these parasites lay they're eggs on them.

 If you take a close look on the patches on the goldfish you can actually see the Argulus moving its little legs swiming with the current, that guaranties the diagnosis. Good luck!! Hope I'm not too late...

The safest way to sterilize any aquarium items without using chemicals is to just put them in boiling water for several minutes and then let the items air dry. This will kill any kind of parasites or viruses that could be on those items.  Just use common sense and don't put items like your thermometer or live plants in boiling water  Grin ;other than that most items than be sterilized this way.

I have got three fish. Two of them have this weird white stuff on their back fins. So the pet store told mr to use a wide variety antibiotic. I started that yesterday. I noticed on my large goldfish that he is getting black spots. Today he has several more than he did yesterday. I took the water in to be tested and it is fine. What did I do to my fish?HuhHuh

Where to start. Do you have an aquarium that is sized properly? Do you have filtration? If not, you'll have to obtain ASAP.

Do you know that the tank will have to be cycled?

Your friend was right about the water change, but did he or she tell you to use water treatment that eliminates chlorine, chloramines, ammonia and nitrite? Goldfish waste first turns to ammonia, then nitrite, and finally after your tank is cycled (about 6 weeks) nitrates. This process is called the nitrogen cycle. Once your tank has cycled your fish will be safe from ammonia and nitrites; you'll have to perform weekly water changes of 20 to 30% to remove the nitrates. Filtering systems only remove debris from the water and provide a place for friendly bugs to build. These friendly bugs are the end result of the nitrogen cycle.

The black marks are burns from ammonia or nitrites.

Goldfish lives longer than most cats and dogs; they keep growing for as long as they live, so be prepared to invest in larger and larger tanks. They require quite a bit of space; my standard is 2.5 gallons per inch of goldfish


You should be performing daily water changes of 20% using enough water treatment for the entire tank size until the tank has cycled.

I'm sure this site has articles instructing on the care of goldfish; research and learn everything you can.

Goldfish are complicated creatures.


Best of luck, Venus

 Grin Thank You Venus... I think It also has to do that I put in a lil toys plastic in there wich is made of petrolium oil "I think" Well I took them out and I put them in another tank the sucker fish turned it normal color it seem to look  black and white now its all blck.. So i cleaned the holly tart of the fish tank jst in case it was something else leaving 20% of the old water in the tank that they are in so I dnt know if it makes a diffrence when I put them back in the tank gain. When I went to walmart I asked about my tank its not even a gallon so maybe you are right about the size I am going to get a new tank. I didnt know that goldfish could live that long usually they die on me when I was younger so I just thought it wont last long. Another question there is a total of 3 gold fish how often do I feed them? I was doing it 2x a day cuz they looked hungry and it says on the food to feed them 3x a day so I thought lets go for 2 but my black gold fish dies so i assume i was feeding them to much and this was before I changed the water for the first time so how often do I feed them? and I give them flakes they move there mouths a lot like if there tasting the water what does that mean? lol.... thank you I really appriciate it

Feed more often in less amounts. Feed a variety of foods including frozen de-shelled peas; nuke em till they're soft, not mushy. I feed peas every day and the fish love em. Peas are nutritious too. Feed blanched green leaf lettuce. Flakes are fine too, but hold them beneath the surface so they sink. This keeps the fish from gulping air.

Here's a good gel food recipe that is popular with goldfish keepers

Gel Food Recipe

Feed occasionally, or daily
Blend the following;
2 packet's of unflavored gelatin
1 cup of boiled water

Add the following to the mixture;
can of sardines, salmon, or shrimp
1/8 cup of cooked carrots
1/8 cup of (blanched) frozen and (de-shelled) peas

Once mixture has cooled to room temperature add the following;
1 capsule; all natural multivitamin
2 capsule of flaxseed or fish oil
1 ounce liquid  chlorophyll

Add 1 teaspoon of wheat germ for digestion issues

    *
      How to make goldfish gel food recipe

Pour mixture onto small cookie sheet and refrigerate until set: Freeze excess divided into small portions (plastic bags) until needed. Serve at room temperature.

Your goldfish may not at first like the new flavor of gel food and may require time to become accustom to the taste and the texture.  Have fun experimenting with your own recipes.



I feed my fish 3 times a day.

In the wild, goldfish feed constantly, throughout the day. They have tummies the size of their eyes. Food travels through their digestive system in just a few hours.

Keep a thin layer of gravel in your tank for the fish to peck through; gives em a more natural environment.

Good catch on the decoration. Only place aquarium safe objects in your tank. No drift wood or metal or plastics unless marked safe. Until you upgrade your tank size, it would be wise to leave the tank bare so the fish have more space.

Although ammonia and nitrite poisoning is dangerous; once you start using water treatment and perform daily changes; they are quick to recover.

Don't get a filter with carbon; carbon and the nitrogen cycle don't mix very well.

My oldest fish (comet) is 12 yrs now and 10" long from head to tail. My biggest fish (fantail) is 12" long and 10 yrs old. I've had them since they were small fries. Kept them in an antique fish bowl that held one quart of water. Now they are housed (along with some other goldfish) in a 120 gallon stock tank. I've got approximately 36" of fish.

Time for a bigger tank.

The only way to heal sick fish is clean water and salt... Read on to find out more.....
If you see ANY unusual things in your fish - black/white spots, fluffy growth, small insects etc... Simply do a 50% water change and replace with same temperature, treated water (add dechlorinator).

BUT before you put the water back into the tank, add 2 heaped tablespoons of salt (no anti-caking agents or iodine) per 10 gallons of tank water that your fish are in.

Dissolve the salt and slowly pour back into the tank.

Repeat 10% water changes and replaced with bottled water. At the end of a seven-day course, give your filter a quick rinse in used tank water (NOT TAPWATER).

GOOD LUCK AND HAPPY FISHKEEPING, FROM SANSA

Respond to Ian question:   

Salt if often added to the water to help cure goldfish of different diseases.  This is often the cheapest and most effective way to help a sick goldfish recover.

Re Salt added to water.

Thanks for the answer. I was just confused in terms of adding salt to a freshwater tank (but I know it is only a touch of salt that is added).

Does it still need to be added if you are using other tank chemicals? I have replaced the airstone and filter and am continuing with partial water changes. I have added some new plants also just to see if it helps!  Undecided
