How Often Do Angelfish Lay Eggs? & Eggs Stages

Sharing is caring!

Angelfish are popular aquarium fish. These tropical fish are available in various colors and sizes, which contributes to their widespread popularity among aquarium keepers. They live2-15 years and breed quickly. Furthermore, these fish are resilient and easy to care for.

If you choose to breed these species, you might have to handle a large number of eggs. But the issue that has to be answered is, how often do angelfish lay eggs?

How Often Do Angelfish Lay Eggs

Angelfish may lay anywhere from 150 to 1000 eggs in a single laying; however, the exact number depends on the Angelfish sub-type and size. Additionally, Angelfish adult pairs can produce eggs every two weeks.

Let’s discuss more about angelfish breeding along with everything about Angelfish eggs.

Do Angelfish Breed Easily?

Angelfish are easier to breed than much other fish. If the proper conditions are provided, angelfish can be bred easily without any stress. Additionally, seeing them as they reproduce, hatch, and mature into adult angelfish may be entertaining.

Here is how you properly breed Angelfish:

1. Prepare the Tank

In order to successfully breed angelfish, you need to prepare the tank in which they will be placed. If you want to easily and conveniently mate your fish, you should look for a tank that is larger than 20-25 gallons.

Angelfish will not reproduce if they are kept in close quarters. As a result, you have to make certain that you choose a spacious tank to keep them.

2. Set up A Good Filtering System

To make it easy for your angelfish to breed, you also need a good filtering system in the tank. Angelfish are an excellent choice for areas with strong currents.

You should avoid using a high-flow filter for the tank since it will wear them out quickly. You may use a gravel filter, sponge filter, or both to give your fish adequate energy and avoid fry-sucking.

3. Adjust the Water Temperature

Another important step in creating a tank for your Angelfish is to adjust the temperature of the water in the tank.

Angelfish are robust and can reproduce in various temperatures, although they grow best in warm water. The water temperature should be in the range of 78 to 86 degrees Fahrenheit.

4. Adjust Water pH

In order for your angelfish to reproduce successfully, the water’s pH has to be adjusted appropriately. Angelfish are unable to reproduce successfully in environments with pH levels that are too high.

Ensure the aquarium’s pH is between 6.0 and 8.0 since they enjoy slightly acidic or basic water.

5. Provide an Appropriate Diet

This is also essential. It is because an angelfish that is not given the necessary diet will not produce healthy eggs. They don’t have many food preferences, so you won’t have to worry too much about what they will eat. Make sure they are fed at least twice or three times a day at the very least.

How to Know if Angelfish Eggs are Fertilized?

The color of the angelfish eggs is the best way to tell if they have been fertilized. In most cases, it ranges from amber to brown, which provides a strong indication of their general state of health.

If your Angelfish eggs have been fertilized, you will notice the following additional signs:

  • Fertilized eggs have more stability than unfertilized eggs; thus, they float for a short period of time in the water before sinking. The oil globule, which can only be found in an egg that has been fertilized, is the source of this egg’s buoyancy.
  • Fertilized eggs have a glue-like consistency, which allows them to attach to the breeding site, which can be a leaf, slate, or any other vertical surface; in certain cases, it can even be the wall of the tank.
  • Furthermore, healthy eggs are clear and clean. You can observe oil globules, a yolk sac, and Angelfish larvae through the eggshell.

Angelfish Eggs Stages

Angelfish have a quick yet complex breeding process from egg laying through hatching. So, let’s discuss all the stages from which the angelfish egg must pass.

1. Cleaning Up The Breeding Location

Angelfish will start cleaning the tank in preparation for reproduction when they reach sexual maturity. Mating angelfish clean the spawning place so the female can lay eggs.

During this process, they are very careful, and it may take them an entire day to do it. However, that doesn’t mean the breeding area won’t change in the future.

Many people put a special slate in the tank just for breeding, which the angelfish can find helpful when it comes time to lay their eggs. If this is the case, you can transfer the eggs to another tank without risking their safety before they hatch.

2. Laying The Eggs

After the spawning place has been cleaned up thoroughly, the female fish will go to work and will lay all of her eggs in a vertical orientation. The male swiftly follows suit and fertilizes the eggs by brushing them, acting as if he were a well-oiled machine in the process.

Several clear eggs, each smaller than the eye of a needle, will be stuck to the hatching area.

The time between laying eggs and when they hatch is very important; this is when you, as the caretaker, can help. You have to remember that angelfish will only reproduce if the conditions in their aquarium are absolutely correct.

Because of this, it is best to avoid making any unexpected movements or alterations to the conditions of the tank around them. They are easily startled.

For reasons that are easy to understand, some Angelfish species move the fertilized eggs to a more compact aquarium. After that, you must perform a water change equal to one-fourth of the capacity of the tank each day.

In addition, continual monitoring is essential, and you need to eliminate the eggs that have not been fertilized in order to safeguard the healthy ones.

3. Pre-hatching Stage

Within a few short hours of the female laying her eggs, the male Angelfish will have fertilized them. In most cases, the color of the egg changes to a shade of brown or amber after it has been fertilized over a period of thirty hours.

As the egg starts to get clear, you can also see some movement inside. Through the lens of a microscope, one can plainly observe both the beating of the heart and blood flow.

4. Larval Stage

During this stage, the eggs begin to move around on their own and become autonomous. After an average of two to three days from hatching, the larval stage has begun.

Larvas look like worms and tadpoles. In addition, these larvas are held in place at the mating site by a filament that runs from the egg yolk to the spawning site. Larvas receive their nourishment from the egg yolk at this stage of development.

5. Fry Stage

The larva will eventually develop into independent fry after an incubation period of one week. Fry is no longer reliant on their parents and is able to swim for some distance. But some of them still hold on to their parents for a few days.

During this stage, the fry doesn’t have egg yolk to eat as it did in the larval stage, so you should feed it well.

6. Final Stage

Some day after the Fry stage, these little fries give the appearance of a little angelfish.

How Can Angelfish Eggs Change Color?

Angelfish eggs can change color due to numerous reasons, such as:


Infertility can be seen if the eggs never become amber but instead turn white or change their normal color. It indicates that the male fish is sterile, and the only way to fix the problem is to try to reproduce with a different pair of fish.

Water Issues

The state of the water is yet another component that has nothing to do with the fish but yet has an effect on the eggs or the fertilization process. An excessive amount of ammonia or nitrates is harmful to eggs. As a result, the eggs change their color.

Fungus Growth

An infection caused by fungi is the primary factor for the opaque white coloration of angelfish eggs. Because of all of these potential contributing elements, the fungus may attempt to infect the eggs; thus, you must be vigilant. Additionally, ensure that the water is clean, and wash both tanks before moving the eggs between them.

Tip: Add methylene blue if there are more white eggs than healthy eggs. There is no assurance; however, there is a possibility that you could rescue some of the eggs.

How Long Does It Take For Angelfish Eggs To Hatch?

The incubation period for your angelfish eggs is rather short once they have been delivered. Once the female has laid the egg and the male has fertilized it, it might take anywhere from thirty-six to forty-eight hours for the eggs to hatch, which is roughly equivalent to one or two days. After a period of 24 hours, you will begin to see a difference in the look of the egg.

These will only work if the water and environment are right for the eggs to hatch. If the conditions for hatching are too severe and unfavorable, the eggs could not hatch at all, or even worse, the embryo may die. In order for the eggs to develop normally and hatch successfully, you will need to fulfill all of the necessary conditions.

Do Angelfish Eat the Eggs That They Laid?

Yes. Sometimes Angelfish eat their own eggs, especially those pairs who are producing eggs for the first time. Additionally, Angelfish can eat their eggs if the environment is not favorable, such as not being given adequate feed or being stressed for any reason.

Angelfish may also sometimes consume their own dead eggs because the dead eggs may become infected with fungus, which would then spread to the healthy eggs and harm them as well. So, to protect the healthy eggs, Angelfish may consume the dead ones.

What to Do When Angelfish Lay Eggs?

After your angelfish has finished laying its eggs, it is your responsibility to care for them. Your angelfish may not be able to guard and care for the eggs if they are a new parent or if they are in a community tank. You are responsible for providing care for the eggs and shielding them from harm from all of the other inhabitants of the tank, including the parents.

Ideally, the eggs should be removed from the tank as soon as possible to ensure the best care. You must care for them until they hatch after removing them from the aquarium. This method ensures the eggs’ continued safety.

How Many Eggs Do Angelfish Lay?

Depending on Angelfish specie, length and size, an angelfish can lay anywhere from 150 to 1000 eggs simultaneously (as discussed above). If you leave the eggs with the pair, they won’t lay again until either eggs or hatchlings are removed.

If you quickly separate the eggs, the couple will be able to continue producing eggs around once every two weeks.

Why Do Angelfish Eggs Turn White?

Infertility or fungal diseases usually cause white eggs; however, there may be other causes too. The key is to keep a close eye on the eggs for signs that they are not fertile.
