Have you recently started noticing that your precious goldfish is turning white? Are you wondering what could be the cause? Should you be worried or not?
Today, we will answer all of your questions and help you understand why your little friend is suddenly changing colors.
There are several reasons why your goldfish might be turning white. Some of the reasons can be worrisome, while others can be completely harmless.
Hence, it is crucial to understand why your goldfish might suddenly lose its vibrant colors.
Why Is My Goldfish Turning White?
For better understanding, let’s divide the reasons why your goldfish may be turning white into three major categories.
- Firstly, consider the possibility that your goldfish may be turning white due to natural or inherent causes.
- Secondly, rule out any external environmental factors that may have a direct impact on the color of your goldfish.
- Lastly, your goldfish may be trying to tell you that it’s not well when it starts turning white. The color change could indicate an underlying health problem.
Now let’s get right into discussing all these reasons in detail ahead.
1) Natural Causes
Let’s first look at some of the natural causes that can make your Goldfish turn white. Since these are natural, you don’t need to worry about them.
Your Goldfish is Getting Older (Aging)
As nature’s rule, all species exhibit some form of physical attributes indicating their biological age.
Similarly, a goldfish may display a change in its color to estimate its age.
Aging is one of the most common reasons your goldfish turns white. It is also a benign cause and a fact that can be compared to your hair turning gray as your age.
However, aging may not always be why your goldfish turned white in the absence of sickness.
Some goldfish species are naturally supposed to be all white or have specs of white on their body surface.
All goldfish are expected to morph as they age. Yet, you can tell whether your fish changed color due to aging or was genetically supposed to look white only.
A simple way to crack this mystery would be to have a look at your goldfish parents.
If your goldfish had parents that were white, the chances of your fish being white due to genes are highly likely.
However, the information regarding your goldfish parents or gene pool may not always be available.
In such a case, your best bet would be to know the age of your goldfish when you buy it. This will allow you to expect when your goldfish will change its color naturally.
Furthermore, knowing the pace at which your goldfish turns white is also an essential factor. If your goldfish changes color at a slower rate, aging is most likely the cause.
Your Goldfish is White Genetically
As previously discussed, genetics have a huge role in turning your goldfish white.
It may come as a surprise to some, but goldfish are not gold in the wild. Goldfish are supposed to be olive green in color.
Selective breeding is the main reason why most goldfish look gold and why there are so many goldfish in different vibrant colors.
However, it must be taken into account that such colors given to goldfish are more likely to fade out than their natural color.
Hence, genetic interference in goldfish breeding is also a common reason your fish is prone to turning white.
Although selective breeding results in such a drastic change in your goldfish’s appearance, it leaves no impact on its health or the environment.
Therefore, it is yet another innocent reason your goldfish is turning white.
2) External Factors
Now let’s look at some external factors that can lead to your goldfish losing color and turning white
Lack of Sunlight Exposure
The natural habitats of goldfish are open water bodies with ample exposure to sunlight.
Hence, it is not unusual for your goldfish to turn white in the absence of adequate exposure to sunlight.
Goldfish kept in aquariums far from natural light sources are more likely to go pale.
It is true that aquariums are preferred to be kept away from sunlight. However, UV rays in the sunlight are essential to impart their vibrant gold color.
UV rays are responsible for activating color pigments present in the goldfish.
The more exposure your goldfish gets to sunlight, the brighter it will become. The opposite is also true.
Hence, one of the main reasons your goldfish is turning white is that it is not receiving enough sunlight.
The effects of lack of sunlight can be reversed if picked early on. Your goldfish will first turn gray from the bottom.
If you notice this, it’s time to let your goldfish have some direct sunlight.
You can shift your goldfish from your aquarium into a small fishbowl. Place this bowl in open sunlight for a few hours every day.
It is crucial to bear in mind that overexposure to sunlight can also be harmful to the goldfish. Hence, sunlight exposure must be regulated.
Alternatively, full-spectrum LED lights can be fixed near the aquarium, and they work just as well as sunlight in helping your fish restore its vibrant colors.
Sudden Change in the External Environment
Goldfish are pretty sensitive to sudden changes in their external environment. Such changes, at times, are not even very conspicuous to the owner.
Even a slight fluctuation in pH levels, water hardness, or temperature can result in your goldfish losing its lustrousness.
Sometimes, it takes some time for the owners to figure out what works for their goldfish. Keeping the aquarium temperature between 69 to 73 degrees Fahrenheit is advisable.
The pH levels best suited for your goldfish are primarily neutral. The water hardness depends on the minerals present in the tank water.
Dirt and fecal matter must also be regularly removed from the aquarium. Subsequently, your goldfish will have a clean and consistent environment to strive in.
It may be expected for such changes in physical parameters to impact the appearance of your goldfish.
What comes as a surprise is that placing decorations can also cause your goldfish to lose its color.
A new mate must also be introduced with caution into the aquarium. It is apparent now that any environmental change can make your goldfish react by turning pale.
If your goldfish is turning white in reaction to such changes, timely help can make your fish revert to its original beautiful colors.
Oxygen Deprivation in the Water
Another critical physical factor that results in your goldfish turning white is a lack of oxygen.
Goldfish are very susceptible to low oxygen levels.
Goldfish are naturally found in freshwater bodies with abundant dissolved oxygen.
If oxygen levels start to drop below 5.0 ppm, it indicates sudden water change. Desired levels of oxygen in tank water are around 8.3 PPM.
In addition to regularly testing the oxygen concentration in the water, notice the paleness of your goldfish.
Almost all causes of your goldfish turning white will make the goldfish appear opaque.
However, a goldfish turning white and translucent is a clear indication of oxygen deprivation.
Low oxygen levels will make your goldfish turn white and make it weak. Your goldfish will start to show signs of lethargy.
Oxygen deprivation must be fixed immediately by replacing more than half of the tank water with fresh water.
Aeration devices can also be placed in the tank for maintenance.
3) Health Issues
And finally, health issues is a major reason why your goldfish may fade in color and look white.
Your Goldfish is Not Getting Enough Food
A goldfish must have a nutrient-rich diet to show its brightest color. The paucity of nutrients in the diet is a significant cause of goldfish losing its lustrousness.
A balanced diet for your goldfish must contain all the vitamins and minerals. A fish that eats healthy will indeed look healthy and bright.
This is a widespread problem that can quickly be addressed.
Suppose you think your fish is going pale due to a lack of nutrients. Start by switching their food.
You can change their regular food with any commercial food brand that will meet your goldfish’s nutritional requirements.
If switching food solves the problem, you will know that a lack of nutrients causes paleness.
You can also opt to supplement your goldfish food with other things like Spirulina algae. Spirulina algae and Bentonite clay have been shown to make goldfish appear brighter.
Your Goldfish is Sick
If your goldfish is turning white rapidly, it can be alarming. Color changes due to benign conditions usually take place slowly in white.
A rapid change may indicate a severe health condition.
Albeit your goldfish turning white is not a disease, it indicates an underlying illness. A sick goldfish will also show other signs of illness like lethargy.
A sick goldfish may not swim as well as it would. Hence, immediate action must be taken to diagnose and treat any disease your goldfish may be suffering from.
A fish that has been recently moved may also go under stress. A stressed goldfish can also result in fading of colors.
Parasite infestations can also be a cause, and thus all fish in the tank must be checked immediately.
