Why Are Angelfish Eggs Turning White? 5 Best Ways To Avoid

Angelfish are beautiful fish, and I would understand if you would want to breed them. There is nothing better than keeping a healthy number of angelfish in your aquarium so that you want to have more angelfish.

You shouldn’t have much difficulty accomplishing this goal if you understand the basics of breeding fish well enough. The female angelfish will lay eggs, which the male angelfish will then fertilize.

However, you will notice that not all things are going according to plan. If you see that the angelfish eggs are turning white, this may cause you to be unsure of what is occurring.

Why Are Angelfish Eggs Turning White? 

Fungous growth is one of the reasons why the eggs of angelfish may turn white. There is a chance that a female fish will lay eggs that are non-fertilized by a male fish.

If this is the case, the eggs will begin to be compromised by bacteria that exist inside the fish tank. A few days later, the eggs will start to grow fungi spores.

Eventually, this will lead to the eggs turning white in color. If you see white eggs in your fish tank, then they are unfertilized eggs.

If unfertilized eggs are exposed to this, there is not much you can do to prevent them from turning white. Rather than saving that eggs, you should focus on why they can’t be fertilized. If you know that there are male fish in your aquarium, you should expect the male fish to fertilize the eggs.

Eggs that have been fertilized do not turn white. There must be something going on to make the male angelfish neglect their eggs. 

Why Would Male Angelfish Neglect the Eggs?

Now you’re wondering why the male fish neglects the eggs. Male fish would fertilize eggs under normal conditions, and everything would be fine.

I believe that there is something happening that is causing the fish to lose interest in the eggs or that they are becoming distracted somehow.

In fact, this is a more common problem than you might think. A large number of angelfish owners run into this issue when they first get their angelfish.

Male angelfish tend to avoid fertilizing their eggs when stressed, which is quite common. Occasionally, angelfish may neglect the eggs when they’re in an area with a high degree of stress or danger. In this case, even if we had the ideal conditions, it is highly unlikely that their eggs would be viable. There are several different reasons why the fish could become stressed in the tank.

The angelfish might be unhappy with the current condition of the aquarium, which could explain their behavior.

There could be issues if you do not place the fish in an optimized tank for angelfish. If you aren’t doing that, then there could be issues that need to be addressed. As much as possible, you should make sure that you provide your fish with a comfortable environment where they feel comfortable enough to fertilize their eggs and look after their young.

There could be a possibility that the males are too distracted to fertilize the eggs.

In addition, it is important to note that angelfish needs to feel comfortable to fertilize the eggs. In fact, if they were concerned about the safety of their eggs, they wouldn’t do it. Female angelfish will lay eggs when they are ready no matter what, but male angelfish will not fertilize the eggs if they don’t feel that it’s safe. 

How Do You Prevent Angelfish Eggs From Turning White?

Consider Moving Your Tank

When the angelfish seem stressed or distracted, it may be because the tank is not located in an ideal location, which might explain their behavior. There is a tendency for people to keep their fish tanks in areas where they can easily observe them, but this isn’t the best for the fish.

In order to be able to look after the eggs and fertilize them, the males need to feel comfortable, so it is not surprising that they would have problems if placed in an area with high traffic. A busy and crowded section of your home is not the best place to keep them because the fish won’t feel safe there.

Consider moving the fish tank to another location that will provide them with privacy. By making this change, you will likely notice fewer issues with unfertilized eggs.

Your fish should be kept in a place where they won’t be disturbed too much. Also, you may want to keep the fish tank up and out of children’s reach. Kids may sometimes tap on aquariums and look at the fish too closely. In a situation like this, the fish are scared, and as a result, the male fish may not feel comfortable fertilizing the eggs.

It is also important to determine if you have other pets that could scare the fish. It is sometimes forgotten how frightening cats and dogs can be for fish.

Avoid The Presence Of Other Fish And Use A Breeding Tank

There are times when the presence of other fish can prevent the male angelfish from getting the job done. Many people don’t take the time to keep the eggs safe by putting their fish in breeding tanks.

I believe that placing a male and a female angelfish in a breeding tank is a smart idea if you are really committed to breeding angelfish. Consequently, this provides a good chance that the fish will be able to fertilize eggs and take care of them until the eggs can hatch.

There are many types of fish that can be paired with angelfish in a standard tank. It’s pretty common for people to keep several different fish species together in the same tank. When the time is right, angelfish might lay eggs. However, other types of fish might try to eat the eggs.

As a result, the angelfish may not be able to fertilize their eggs properly. I think that it is due to the stress associated with worrying about other fish eating the eggs.

This can be avoided by using breeding tanks properly. As long as you have the space for a breeding tank, you won’t have any trouble setting things up.

Be Sure The Eggs Are Not Laid In Fast-moving Waters

The first thing you need to do before you blame your angelfish for not completing his role is to make sure his breeding site is not in the vicinity of water with fast currents.

When the female fish lays eggs near fast-moving water, although the male has sprayed the eggs with his sperm, they will simply be washed away by the water. 

The female angelfish should deposit the eggs in places with still waters.

 Not Feeding The Angelfish Excessively

The decay of waste might also be one of the reasons for the growth of fungi. The food that you feed your fish has a tendency to decay over time while it is floating in the aquarium. 

For this reason, I highly recommend not overfeeding the angelfish. We may normally assume they need more energy to breed, but it is important to note that the accumulation of waste will eventually accelerate the growth of bacteria and fungi.

Strive For Ph Balance

It is also important to note that fungus tends to grow on fish eggs in alkaline water, in which the pH level is relatively high. In an acidic environment, it appears that the fungus is unable to thrive.

You should therefore strive for balance. You should change the water frequently, but not too often. In order to lower the pH levels, do not add more companion fish since they might stress the angelfish. You could try a few chemicals you can easily purchase at a pet store as an alternative.

Should you remove white Angelfish eggs?

Obviously, it isn’t of any use to you if the eggs turn white. They will not produce any new fish since they have reached a point where they are no longer viable.
However, it might not be necessary for you to remove the eggs from the tank manually. In many cases, when the angelfish realize that the eggs are not viable, they will decide to eat the eggs.
This way, the angelfish in your tank might be able to take care of the problem. When the fish do not eat the eggs promptly, then it is time to remove the eggs and dispose of them from the aquarium. Unless you do so, there will be a lot of mess in the aquarium. 

What color should Angelfish eggs be?

The color of fertilized angelfish eggs can range from translucent amber to brown. When you see that your angelfish eggs have any slight variations in color within this range, you can be assured that they are healthy, fertilized, and are likely to hatch successfully.

Will fish eggs hatch with fungus?

When fungus attaches to the angelfish eggs, it will kill the eggs before they hatch.


The question of turning white eggs bothers most fish breeders, including myself. There are several things to consider when you notice fish eggs turning white. If the fish eggs turn white, it indicates that they have fungus growing on them. Moreover, it also suggests that the eggs are not fertilized.

Hopefully, with some adjustments you can make, the fish will start doing what they need to do to make viable eggs. If you’re willing to put in the effort, turning things around shouldn’t be too difficult.
