How Long For Angelfish Eggs To Hatch

Angelfish are a beautiful and popular aquarium fish, but they can also be quite difficult to breed in captivity. A successful breeding cycle requires a lot of patience and attention to detail. One of the most important steps is waiting for angelfish eggs to hatch. In this article, we’ll explore the hatching process for angelfish eggs, including how long it takes for them to hatch, what conditions need to be met for hatching to occur, and other tips for successful breeding. With this knowledge in hand, you’ll be better equipped to start your own angelfish breeding program!

What Are Angelfish Eggs?

Angelfish eggs are small, round eggs that are laid by female angelfish in an aquarium. The female will lay the eggs on a flat surface, such as a piece of driftwood or the side of the tank. The eggs are semi-opaque and light yellow in color.

How Long Does It Take For Angelfish Eggs To Hatch?

The incubation period for angelfish eggs is between 7-10 days depending on the temperature of the water. If the water is too cold, it may take longer for the eggs to hatch. On average, it takes 8-9 days for angelfish eggs to hatch.

Tips For Speeding Up Hatching Time:

  • Keep the temperature at 78-82°F (25-28°C) – This will help speed up hatching time.
  • Maintain good water quality – Ammonia and nitrites should be at 0 ppm and nitrates below 40 ppm.
  • Provide plenty of oxygen – An air stone or filter with an airstone can help increase oxygen levels.

What Happens When Angelfish Eggs Hatch?

When angelfish eggs hatch, they form small fry with yolk sacs attached to their bellies. These yolk sacs provide nutrition to the fry until they can begin feeding on their own. After several days, the fry will become more active and start swimming around in search of food. At this point, it’s important to start feeding them a high quality baby fish food or brine shrimp nauplii.

How Can You Tell If Angelfish Eggs Are Fertilized?

One way to tell if angelfish eggs are fertilized is by observing them for a few days after they’re laid. Fertilized eggs will usually become opaque within 24-48 hours, while unfertilized eggs will remain clear and eventually become fungus-ridden. This method is effective, but it can be difficult to distinguish between the two types of eggs at first glance.

Another way to determine if angelfish eggs have been fertilized is by gently squeezing them with tweezers or your fingers. Fertilized eggs are typically firm and slightly squishy, while unfertilized ones tend to feel hard and dry. Be sure not to squeeze too hard, as this could damage the eggshell and prevent the embryo from developing properly. Additionally, you should avoid touching the eggs too much as this could introduce bacteria that could potentially harm the embryos.

Should I Remove Angelfish Eggs?

No, you should not remove angelfish eggs. Removing the eggs can cause a lot of stress to the angelfish, which can lead to health problems and an increased risk of disease. Angelfish are also relatively sensitive when it comes to their environment and removing the eggs may cause them to become more stressed than usual.

Furthermore, removing the eggs could negatively affect the angelfish’s reproductive cycle. The female angelfish may become less likely to lay eggs in the future if her current clutch is removed. Additionally, if there is any fry present in the tank, they could be injured or killed by being disturbed during egg removal.

For these reasons, it is best to leave angelfish eggs in place until they hatch or are unviable. Doing so will ensure that your angelfish remain healthy and that their reproductive cycle is not interrupted.

How Many Angelfish Fry Survive?

The survival rate of angelfish fry largely depends on environmental factors, such as the quality of water, the temperature and the amount of food available. Generally, angelfish fry have a high mortality rate due to their small size and fragility. In an ideal environment with proper care and nutrition, about 50% of angelfish fry may survive to adulthood.

However, in most cases this number is much lower due to a lack of awareness and proper care from aquarists. The most common causes of mortality include poor water quality, insufficient oxygen levels, overcrowding and poor nutrition. Unfortunately, many aquarists simply add too many fish to their tank without considering the needs of each species. This can lead to overcrowding in the aquarium which can cause stress and result in a higher mortality rate for angelfish fry. Additionally, inadequate filtration systems can also lead to poor water quality which can cause illness or death in the fish.

In addition to these environmental factors, it is important that aquarists provide appropriate foods for their angelfish fry at regular intervals in order to ensure they receive adequate nutrition. Appropriate foods include live foods such as brine shrimp or daphnia as well as commercial flake or pellet foods designed specifically for young fish. Without proper nutrition it is difficult for an angelfish fry to grow and develop into a healthy adult fish.

In conclusion, while there is no exact answer as to how many angelfish fry will survive given each unique situation, it is important that aquarists are aware of the potential risks associated with raising these delicate creatures so they can provide them with the best possible environment for success. With proper care and attention, it is possible for up to 50% of angelfish fry to survive until adulthood under ideal conditions.

What Do You Do After Angelfish Lay Eggs?

After angelfish lay eggs, there are several steps to take in order to ensure the health of both the eggs and the fish.

First, remove any adult angelfish from the tank. This is because adult angelfish will eat the eggs and can become aggressive when guarding them. It’s best to move them to another tank, as leaving them in the same tank may still result in their eating the eggs.

Next, check on the eggs regularly. Angelfish eggs tend to hatch after about four days, so it is important to keep an eye on them during this time and make sure they do not dry out or suffer any other damage while they are hatching. You can also use a sponge filter or an air stone to help oxygenate the water around the eggs and keep them healthy by providing a current of fresh water that helps aerate them and keeps fungus away.

Once your angelfish have hatched, you should move them into a separate tank with plenty of space for swimming. The young fry will need small live food such as baby brine shrimp or microworms so that they can get enough nutrition in order to grow and develop properly. You should also monitor water conditions in the new tank carefully – too little oxygen or too much ammonia can be harmful for young fry and cause health problems later on down the line.

By taking these steps after angelfish lay eggs, you can give your new fish a good start and hopefully get a successful outcome!

Can I Move Angelfish Eggs?

Yes, angelfish eggs can safely be moved. This is typically done when you want to hatch the eggs in a different tank than where they were laid. Before moving the eggs, it is important to understand what environment they need to thrive in and how to properly handle them.

When transferring angelfish eggs, make sure you are using clean water. The temperature should be consistent with the original tank and ideally there should be no more than a 5-degree difference between tanks. When removing the eggs from their original location, use an instrument like a pipette or spoon and avoid touching them directly as this could damage their delicate shells. Place the eggs gently into a plastic container and fill it with clean water from the new tank before transferring them over.

After the transfer, keep an eye on the eggs for any signs of distress or discoloration as this could indicate that something went wrong during transport. Additionally, make sure to provide good aeration and filtration for the new tank so that your angelfish fry have everything they need for successful development.


Overall, angelfish eggs take approximately 5-8 days to hatch. While the hatching process can be unpredictable, understanding the unique conditions and needs of angelfish eggs is necessary to ensure successful hatching. The biggest factors influencing egg hatching are water temperature and oxygen levels, so providing an adequate environment for angelfish eggs is essential for a successful hatch rate. With proper care and attention, you will soon enjoy watching your angel fish fry swim around in the tank!
