We completely understand.
In actual fact, “why is my goldfish turning black” is among the top frequent concerns we get from owners (of any level of experience). Don’t fret that you’re not the only one!
This guide is sure to help you understand the issue. Learn why this happens and what you can do to discover the reason, and if there’s something you can (or ought to) do.
Should You Be Worried?
Watching your goldfish turn black can be frightening. However, it’s not always an immediate sign of danger.
Goldfish can be described as the quintessential “easy” fish to manage. They are readily available in most pet stores, and they can adapt perfectly to your aquarium.
The most famous characteristic of the goldfish is the shimmering gold color. This stunning appearance is the result of hundreds of generations of breeding selectively.
Contrary to what many believe, goldfish are a variety of fish that aren’t naturally gold-colored when they are in their natural habitat. They’re among the first fish species to be domesticated in the past and selective breeding has helped create the species that we see today.
In the end, color changes are more frequent than you imagine. In reality, among the more popular colors for fish is for it to turn black!
If a pristine goldfish suddenly starts to turn black, it’s easy to think that something’s not right. Changes in color to white are much more prevalent than those that change to black. When your fish starts getting darkened up, it’s important to be proactive about the issue!
The change in color of black could be an indication the fish may be experiencing internal issues. There could be an illness that you must address to allow your goldfish to remain healthy.
However, not all instances of changing color in blacks can be life-threatening, or even hazardous. Sometimes, color changes are totally normal for fish.
So how can you tell whether your fish’s color-changing could be a sign of trouble?
You must understand what’s causing this change. It is important to recognize the signs that could be serious and take proactive steps to provide treatment when it is needed.
It is important to take into consideration the possible causes and keep an eye on your fish. Then, you’ll be able to decide if it is necessary to do something about it.
Why Is My Goldfish Turning Black? (Potential Causes)
There are several reasons why goldfish could begin to change color.
As we’ve mentioned before, black color changes are very rare in all kinds of goldfish. So, you’ll have to think about all possible reasons to decide on the most effective course of action.
It is an extremely unstable color for goldfish. The majority of pure black goldfish are prone to losing their color and turning yellow or white. The sight of a good fish darkening up is incredibly rare.
In the end, many think there’s a serious health problem to blame. This could be true however, there are certain causes that are relatively harmless, too.
The causes that could cause the goldfish to turn black can vary in a wide range. Certain causes are simple enough that they don’t require actions, whereas others can be resolved with some minor changes to the way you handle your fish.
There’s an opportunity that this could be an unrelated health issue.
But wait! Before you go into the tizzy wondering why your goldfish has turned black, think about some possible reasons to help you understand more about the reason why a color change is occurring.
Here are the most frequent reasons behind a color change, and the steps are the best way to give some attention to your goldfish.
1. Ammonia In The Tank
Ammonia changes are by all accounts, the main reason behind why goldfish turn black.
The color change usually occurs at the fins. In time, it may become more severe and then extend into the body. It will appear as tiny black patches of skin that appear burnt.
Ammonia is a harmful chemical produced in the fish tank. It’s something that most people don’t know about yet, but taking care of the fish that are kept in captivity can be a continuous fight to prevent ammonia accumulation within the fish tank!
This is the entire purpose of the filtering as well as the cycling system!
Fish create ammonia by releasing waste. The decomposition of plant matter and uneaten food could trigger ammonia surges too. Most aquarists can keep ammonia levels low by keeping the tank clean regularly.
Water changes are extremely effective in eliminating the chemical. A powerful filtering system will aid in this process as well. If the tank isn’t properly cleaned the levels of ammonia can climb very quickly.
This chemical could be used to cause death to fish. And to make matters worse the tank doesn’t need an excessive amount of it to cause death. Even a tiny amount at 2 parts of a million would be sufficient to kill fish that are small, like the goldfish. The ideal ammonia levels should be at 0 PPM.
What is the reason why ammonia causes the color of black to change?
It’s in essence burning the skin of your goldfish. Ammonia is the reason why it kills fish. The higher concentrations of ammonia can cause gill damage.
The good news is that when you see that your goldfish turn black could actually be an indication it is doing well.
It’s difficult to detect ammonia in water. It’s impossible to tell how the chemical is burning your fish’s body, either. The black spots on your goldfish are a sign that your organism is recovering.
It could mean that levels have dropped to a more secure level. But, don’t take any of this as a guarantee! Get your test kit and examine the water. Anything over 0 PPM should be a concern.
You’ll then want to examine all the aquarium fish. There could be strange swimming patterns or slow breathing. These are signs that indicate ammonia poisoning. If you’ve got sick fish, transfer them to an area that is a quarantine tank.
Stressed and sick fish release tons of ammonia. However, the high levels of ammonia can only worsen the issue.
Verify the conditions of the water and take out decaying plants or leftover food. It is possible to think about changing the way you feed your fish, too.
As a general guideline, you should give enough food to ensure that your fish will be consumed in just a few minutes (this will vary dependent on the species, of course). Then, you can remove all excess food to ensure ammonia levels do not rise and then drop again.
Then we can look at a more innocent reason. Goldfish can be genetically predisposed to color changes. While the possibility of a fish turning black is not common, it’s possible!
“Mixed breed” goldfish are the most likely to experience certain changes in their lives. These are generally the less expensive goldfish that you can find at the market. They could have odd color patterns.
The fish can change color as they move from the young stage into the adult stage. The transition occurs in the first one or two years. The changes are gradual and you may not even be aware of them initially.
Goldfish can form darker black patches on its body. It may also result in certain areas becoming lighter.
“Purebred” goldfish that comes from a reliable breeder may be a bit black too. But, the transformation tends to be less noticeable. It is possible to see black streaks from around the fins or even tiny dark-colored dots.
Whatever the reason, the possibility of a goldfish turning black due to genetics is nothing to be concerned about. It’s perfectly normal and does not cause any health problems or a shorter lifespan.
Goldfish that turn black due to disease is not common however, it’s still possible to consider it. The condition in question is known as the black spot.
This is much more common for goldfish that are kept in ponds, rather than in aquariums with enclosed enclosures. It is also a problem for fish caught in the wild. Many fishermen come across fish who suffer from this disease all the time.
So, what exactly is the black spot disorder? It’s a virus that causes a parasitic infection. Fish are able to catch it from water snails that are infected. Goldfish living in ponds may get the disease when the bird’s droppings get to the water.
If a fish is suffering from Black Spot Disease, the fish create spots that are literal on the body. The symptoms can vary quite a lot too. In the case of mild instances, you may spot a few spots here and there.
However, serious infections can substantially cover the goldfish black.
If you think that a disease is a reason, take an examination of the behavior of your goldfish. The spots are typically itchy, which is why fish move their bodies around and attempt to rub on objects in order to ease the pain.
To treat this illness, you must eliminate snails from your environment. This could end the cycle of life of the parasite. It will take some time, but the fish will be able to recover.
Although it sounds like a horrible disease it’s believed to be less risky than I.C.
Also, black spot disease is rare. If you don’t keep your goldfish in a pond that is outdoors fish, your odds of catching it are slim.
Is It Possible For Them to Reclaim Their Original Colour?
The issue is the source. If your goldfish became black because of something harmless like diet or lighting it’s possible. Certain fish may be refreshed and display their gold-colored shine again!
There are, however, no assurances. Sometimes, the problem is persistent. This is particularly true for genetic changes or old age diseases.
So long as you take care to address any issues with your health or comfort such as a lack of coloration, it is not an issue. Your fish will still be able to be healthy despite being dark! Take it as a fresh physical flaw!

The sight of these gorgeous fish becoming darker over time is a sad sight initially. It’s often an inevitable thing to happen.
Follow our guidelines. Make sure you take the required tests and follow the recommended procedure. The majority of the time, the answer is quite simple.
