How To Tell If Angelfish Eggs Are Fertilized

Many people keep angelfish as pets in their home aquariums.

But not all of them know how to determine if their angelfish eggs are fertilized.

If you’re one of those people and looking for some tips, you are in the right place.

In this article, we’ll go over a few ways that you can tell if your angelfish eggs are fertile or not.

Also, we will provide you with some tips to care for the eggs if they are fertilized.

What is The Right Color For Angelfish Eggs?

The right color for Angelfish eggs is brownish amber. If they are white and opaque, the eggs are not fertilized.

Unfertilized Angelfish Eggs

  • If the egg is white or has a pale color, it indicates that the eggs are unfertilized.
  • The eggs are see-through; they’re just not translucent.
  • You can’t detect any movement within it.
  • The worst type of white egg is the fuzzy white one. This implies that the eggs are afflicted with mold and are most likely dead.
  • Unfertilized eggs are also less sticky than fertilized ones. As a result, these unfertilized eggs do not adhere to the spawning site and float in the aquarium.

Fertilized Angelfish Eggs

  • The color varies from yellow to orange.
  • Oil droplets, yolk sacs, and angelfish larvae may be viewed through the shell.
  • The eggs will adhere to the spawning site, which could be a leaf, slate, any vertical surface, or even the tank wall if fertilized.

How Do Parents Angelfish Behave If The Eggs Are Fertilized?

Do you know that Angelfish parents display a specific behavior when they’re sure they’ll receive fry soon?

Yes, Angelfish parents can determine if their eggs are fertilized. When this happens, you’ll notice Angelfish parents using this behavior:

  • Cleaning the area surrounding the spawning site
  • Nipping at any fish that passes by their eggs
  • Fanning the eggs to provide aeration

You should not be shocked if you see an Angelfish parent swallowing their young only to spit them onto a secure vertical surface.

This is because angelfish parents, especially experienced parents, fiercely protect their young.

Also, if you observe an angelfish becoming aggressive and battling with other tank mates, there’s a good chance the eggs have been fertilized.

How Long Does It Take For An Angelfish Eggs To Hatch?

In ideal situations, eggs will hatch approximately 60 hours after being laid.

To be honest, the following factors also have a role in early hatch:

Stages of A Fertilized Angelfish Eggs

The following are the three developmental stages of a fertilized Angelfish egg:

Pre-hatching Stage

The male Angelfish fertilizes the eggs within hours of laying. At this stage, eggs are generally brown or golden after 30 hours of fertilization. As the eggs get more translucent, you may see some movement within them.

Wriggler Stage

At this stage, the eggs are broken, and the yolk is injected into the wrigglers. The larvae of angelfish and other fish species are tiny. They resemble worms, but they’re not. This larval phase lasts around 2-3 days after hatching. 

Fry Stage

The fry transform into independent fry after 6-7 days of hatching.

Some of the fry do not rely on their parents and swim a few distances.

On the other hand, some cling to their parents for a few days.

During this stage, the fry does not have egg yolk (like the wriggler phase) to keep itself nourished, so you should give it a balanced diet.

How Can You Help to Fertilize and Save the Fertilized Angelfish Eggs?

Sexing Angelfish Properly

The sexing stage is perhaps the most frequent mistake when breeding Angelfish.

And the reason is that it’s difficult to determine the gender of an Angelfish.

But if you do it successfully, you’ll be able to solve 25% of the problem.

Male angelfish are larger and have a round body. Their breeding tube is similar to those of a pencil tip. They have forked ventral fins and develop faster than female angelfish, and their forehead bump is quite distinct.

On the other hand, a female angelfish has a sloping facial profile with no forehead bumps. The ventral fins are rounded and smooth, and the breeding tube is wide and blunt.

Get a Separate Tank

If you’re not willing to have eggs and fry in your main tank, you should get a separate tank to breed Angelfish.

This will ensure that the eggs and fry have a better chance of hatching and growing without being eaten.

Provide a Platform Like Slate for Laying Eggs

Angelfish lay their eggs (spawn) on a platform above the water, such as leaves or vegetation. So, providing your Angelfish with a place to lay their eggs will soothe them.

You can also give your fish any artificial or natural green leafy plant. This will help the female lay her eggs on it.

Prevent Fungus Development

You’ve probably heard about the fungus issue in Angelfish eggs.

1-3 drops of Methylene Blue solution can help you avoid (and even reverse) this problem. Use the remedy without a filter and watch your sickened eggs recover.

Methylene blue, on the other hand, should be used in moderation. Excess methylene blue may be harmful to live fries and eggs, so you should be careful.

Maintain Water Flow

You should also ensure a good water flow in the tank. This will help to oxygenate the water and keep the eggs healthy.

Set Up an Active Filter to Keep the Eggs Clean

To ensure the best chances of developing, angelfish eggs need clean water free of waste and toxins.

Therefore, you should use an aquarium filter to maintain water quality and to prevent the eggs from getting dirty and infected.

Keep Friendly Tank Mates

If you aren’t going to keep the eggs in a separate tank, at least maintain peaceful tankmates.

Some good tankmates for Angelfish are:

  • Larger tetras and rasboras.
  • Gouramis.
  • Peaceful barbs.
  • Rainbowfish.
  • Corydoras.
  • Other medium-sized catfish.

Take Care While Separating Eggs

If you’re going to move the eggs, do so with a gentle touch as they are quite delicate.

Use a soft cup or spoon to move them and then place them in the breeding tank.

If you’re not going to move them, then be sure to keep an eye on them so that any fungus doesn’t develop.

Reasons Why the Angelfish Eggs Aren’t Fertilized and Die-off

When you notice white Angelfish egg clusters, you’ll have no idea what happened. Here are the causes of your Angelfish eggs failing.

Wrong Sexing and Fertility Issue

Female angelfish can produce eggs without a male angelfish present, but the eggs will not be fertile.

If you think you have a male and female, but you always find unfertilized eggs, you likely misidentified the sex of one or both of your angelfish.

Immature Or Inexperienced Angelfish

Many seasoned Angelfish owners have claimed that a first-time breeding Angelfish isn’t concerned about their youngsters.

Angelfish are only produced by inexperienced Angelfish who have had two or three breeding experiences.

So, if you’re breeding your Angelfish for the first time, prepare to lose some eggs.


Fungal infections are prevalent among Angelfish eggs!

The fungus can grow on the eggs if they are placed in filthy water, the tank contains algae, or poor water conditions. The eggs turn white as a result.

This fungus grows gradually until all the eggs are destroyed.

Bad Water Parameters

When egg-laying Angelfish are hatched, they must be handled with extra care, especially since the eggs aren’t fish.

Will you believe me when I tell you that extreme water parameters, such as high or low pH, temperature, and unclean tanks, may kill an entire egg colony overnight?

That’s right, so believe me, you need to keep a close eye on water parameters when your angelfish are spawning.

Bad Place to Lay Eggs

The eggs may simply perish if you don’t provide some additional layers and plants in your tank.

Angelfish, for example, lay their eggs in the substrate if there are no platforms or leaves available.

There isn’t enough oxygen in the substrate. As a result, all of the eggs die off.

Also, some eggs are laid in the heater, which solidifies the eggs. This process causes angelfish eggs to transform into omelets.

Harsh Water Flow

Strong water movement might dislodge the eggs from their vertical surfaces and float away, causing them to die or to be food for other fish in the tank.

Additionally, harsh water flow can wash the sperm off the eggs preventing fertilization from taking place.


This is a sad story to hear. Angelfish have been known to consume their own eggs due to stress.

So, if you keep them in a colony tank with other fish, they may eat their eggs.

Here is a youtube guide answers Why do my angelfish eggs keep turning white?

How Do You Get the Fertilized Eggs Out of the Unfertilized Ones?

These tiny eggs are quite delicate, therefore you must use tweezers to separate the fertile ones from the rest.

Remove the breeding slate from the old tank and gently remove the fertile eggs with a pair of tweezers, placing them on any suitable surface. After that, it’s all about creating the correct environment for hatching.


Can Angelfish Lay Eggs Without a Mate?

Angelfish can lay eggs without a mate. However, the eggs won’t hatch since there’s no male to fertilize them.

What Does It Mean When Angelfish Eggs Turn White?

Many factors can cause an angelfish to get white, including a fungal infection or the eggs being unfertilized.

How Many Eggs Do Angelfish Lay at Once?

On average, Angelfish lay anywhere from 100-1000 eggs at a time. The number of eggs an angelfish produces is directly related to its size and health.

How Often Do Angelfish Lay Eggs?

Pregnant angelfish can lay eggs every two weeks or even less if you remove the eggs immediately after fertilization. However, if you leave them in the tank, the parents won’t breed until you separate the eggs.

Where Do Angelfish Lay Their Eggs?

Female angelfish deposit their eggs in rows on vertical surfaces, whether it’s a removable leaf, the tank heater, breeding slate, or even the tank walls.

Male Angelfish Eating Eggs, What to Do?

Stress and inexperience are the two most common reasons for a male angelfish to consume its own eggs.

Several variables can cause stress, including a crowded tank, rapid water movement, commotion, or water-quality changes. Also, lack of nutrition can result in the male eating its own eggs.

Angelfish Keep Laying Eggs on the Filter, Glass, and Heater. What Should I Do?

Angelfish lay their eggs on vertical surfaces, thus you’ll need to provide them with an alternative. Provide your angelfish with a breeding slate or the Amazon sword, which has vertical leaves that are ideal for egg laying.

My Angelfish Is Laying Eggs But They Keep Vanishing. Why?

If your angelfish are laying their eggs in the open, it’s likely that other fish in the tank are eating them.

Another possibility is that the eggs are infertile and are being eaten by the parents. This usually happens when the male and female are not properly conditioned or if there’s something wrong with the water quality.

Do Angelfish Eat Their Own Fry?

Angelfish might eat their own fry, but this is usually only a problem if the tank is overcrowded or if the parents are starving.

Are Angelfish Hard to Breed?

Angelfish are not difficult to breed if you have a pair of healthy, well-conditioned fish. However, there are many factors that can affect the success of breeding, such as water temperature, tank size, pH level, and water quality.

What Does Angelfish Fry Eat?

Angelfish fry eats small foods, such as baby brine shrimp or infusoria. The fry will need to be fed several times a day until they’re big enough to eat regular food.

Last Words

Now that you know what can happen to your Angelfish eggs, it’s time for you to take the necessary precautions!

Remember to keep a close eye on your water parameters and provide a safe place for the eggs to be laid.
