In this article, I’ll cover everything you need to know about Marble Angelfish. Whether you’re a seasoned fish owner or a beginner, you’ll find valuable information to help you care for these stunning fish. So, let’s dive in and learn more about these fascinating creatures.

Marble Angelfish

Species Summary


The Marble Angelfish, also known as Pterophyllum scalare, is a freshwater fish that is native to the Amazon River Basin in South America.

It was first discovered in the early 1900s and has since become a popular choice for aquarium enthusiasts around the world.


The Marble Angelfish has a lifespan of around 10-15 years when kept in ideal conditions.

However, their lifespan can be shortened if they are not properly cared for or if they are kept in unsuitable environments.


The Marble Angelfish is a beautiful fish with a unique marbled pattern on its body. They have elongated triangular bodies and long vertical fins that make them look elegant in the water.

The marbled pattern on their body can vary in color from light gray to dark brown, and they have a distinctive black stripe that runs through their eyes.


The Marble Angelfish can grow up to 6 inches in length, making them a medium-sized fish. However, their size can be influenced by factors such as water quality, diet, and tank size.

Growth Rate

The growth rate of Marble Angelfish can vary depending on their environment and diet. In ideal conditions, they can grow up to an inch in length in just a few months.

Behavior & Temperament

The Marble Angelfish is a peaceful fish that gets along well with other non-aggressive species.

They are known to be shy and can take some time to adjust to their new environment. Once they are comfortable, they will become more active and curious.

Male vs Female

It can be difficult to distinguish between male and female Marble Angelfish, as they look very similar. However, females tend to have a rounder and fuller body, while males have a more pointed anal fin.

Personally, I have always been fascinated by the Marble Angelfish. Their unique marbled pattern and elegant appearance make them a beautiful addition to any aquarium.

I remember the first time I saw one in a pet store and was immediately drawn to their beauty. Since then, I have kept several in my own aquarium and have enjoyed watching them grow and thrive.

Tank Setup

Setting up a suitable tank for your Marble Angelfish is crucial for their health and happiness. Here are some important factors to consider:

Tank Size

The minimum recommended tank size for a pair of Marble Angelfish is 30 gallons.

However, a larger tank is always better as it provides more swimming space and allows for a greater variety of plants and decorations.

I personally keep my Marble Angelfish in a 55-gallon tank, and they seem to love it.


Marble Angelfish prefer subdued lighting, so it’s best to use low to moderate lighting in their tank. This will also help prevent algae growth, which can be an issue in brightly lit tanks.

Filtration & Aeration

A good quality filter is essential for maintaining water quality in the tank. A canister filter or a hang-on-back filter is recommended.

Additionally, aeration is important to ensure sufficient oxygen levels in the tank. I use an air stone to provide additional aeration in my tank.


Marble Angelfish are tropical fish and require a consistent water temperature between 76-82°F. A reliable heater is essential to maintain the correct temperature in the tank.


A fine-grained substrate, such as sand or gravel, is recommended for Marble Angelfish. Avoid using sharp or coarse substrates, as they can damage the delicate fins of the fish.


Marble Angelfish prefer a heavily planted tank with plenty of hiding places.

Rocks, caves, and driftwood can also provide hiding places and add visual interest to the tank. I like to include a few clay pots in my tank, which provide great hiding places for my Marble Angelfish.


Live plants are a great addition to a Marble Angelfish tank. They provide oxygen, help maintain water quality, and provide hiding places for the fish.

Some good plant choices for a Marble Angelfish tank include Java fern, Amazon sword, and Anubias.

By taking the time to set up a suitable tank for your Marble Angelfish, you can provide them with a comfortable and healthy environment to thrive in.

Remember to monitor water parameters regularly and perform regular water changes to maintain optimal water quality.

When I first set up my Marble Angelfish tank, I made the mistake of using a bright light and sharp gravel substrate. My fish were stressed and unhappy, and I quickly realized my mistake.

After making some changes to the tank setup, my Marble Angelfish are now thriving and happy. Trust me, it’s worth taking the time to set up the perfect tank for your fish!

Water Quality

As a proud owner of Marble Angelfish, I know how important it is to maintain proper water quality in their tank. Here are a few things you need to know about water quality:

Water Temperature

The ideal water temperature for Marble Angelfish is between 75-82°F (24-28°C).

It is important to maintain a consistent temperature, as sudden changes can stress the fish and make them more susceptible to diseases. I always use a reliable heater to ensure that the water temperature is stable.

Water pH

Marble Angelfish prefer a slightly acidic water with a pH level between 6.0-7.5. It is important to test the water regularly to ensure that the pH level is within the acceptable range.

If the pH level is too high or too low, it can cause stress to the fish and affect their overall health.

Water Hardness

Marble Angelfish prefer soft to moderately hard water with a hardness level between 3-10 dKH. Hard water can cause health problems for the fish and affect their ability to breed.

I always use a water conditioner to ensure that the water hardness is within the acceptable range.

Water Changes

Regular water changes are essential to maintain good water quality for Marble Angelfish. I recommend changing 20-30% of the water every week.

This helps to remove any accumulated waste and toxins in the water, and also replenishes essential minerals and nutrients that the fish need to thrive.

By maintaining proper water quality, you can ensure that your Marble Angelfish live a healthy and happy life in their tank.

Remember to test the water regularly, use a reliable heater and water conditioner, and perform regular water changes to keep the water quality in check.

Tank Maintenance

Keeping a clean and healthy environment for your Marble Angelfish is essential for their well-being. As an aquarium owner, I have found that regular maintenance is the key to keeping my fish happy and healthy.

One of the most important aspects of tank maintenance is water quality. I test my water regularly to make sure that the levels of ammonia, nitrite, and nitrate are within the safe range for my fish.

I also perform weekly water changes of 20-25% to remove any excess waste and debris.

In addition to water quality, it’s important to keep the tank clean. I use a gravel vacuum to remove any uneaten food and waste from the substrate. I also clean the glass and decorations with a soft sponge to prevent algae buildup.

Another important aspect of tank maintenance is monitoring the temperature and pH levels. Marble Angelfish thrive in water that is kept between 75-82°F and a pH level of 6.5-7.5.

I use a thermometer and pH testing kit to ensure that the water is within the optimal range for my fish.

Lastly, it’s important to keep an eye on the overall health of your fish. I observe my Marble Angelfish daily to make sure that they are swimming and eating normally.

If I notice any signs of illness or stress, I take immediate action to address the issue.

In conclusion, tank maintenance is crucial for the health and well-being of your Marble Angelfish. By maintaining water quality, cleanliness, and monitoring temperature and pH levels, you can ensure that your fish live a happy and healthy life.

Tank Mates

Compatible Fish Species

I have found that Marble Angelfish are generally peaceful and get along well with other non-aggressive fish species. Some good tank mates for Marble Angelfish include:

  • Tetras
  • Gouramis
  • Corydoras Catfish
  • Otocinclus Catfish
  • Platies

It’s important to note that even with compatible species, it’s always a good idea to monitor their behavior and ensure that there is enough space in the tank for all the fish to live comfortably.

Incompatible Fish Species

While Marble Angelfish are generally peaceful, there are some fish species that they may not get along with. Some incompatible species include:

  • Aggressive Cichlids
  • Large Catfish
  • Sharks
  • Some types of Barbs

If you’re unsure whether a certain species will be compatible with your Marble Angelfish, it’s always a good idea to do some research or consult with a knowledgeable aquarium specialist.

How Many Marble Angelfish Should Be Together

In my experience, Marble Angelfish do well in groups of 3-5 individuals. This allows them to establish a hierarchy and reduces the chances of aggression between fish.

However, it’s important to ensure that there is enough space in the tank for all the fish to live comfortably.

One time, I made the mistake of adding a large aggressive cichlid to my Marble Angelfish tank. Within a few days, the cichlid had killed several of my Angelfish.

I learned the hard way that it’s important to research and carefully choose compatible tank mates for your Marble Angelfish.


As an aquarist, I have learned that feeding your Marble Angelfish a balanced diet is crucial to their overall health and well-being.

In this section, I will cover what to feed your Marble Angelfish, how often to feed them, and some tips to keep in mind.

What To Feed

When it comes to feeding your Marble Angelfish, a varied diet is key. They are omnivores, which means they eat both plant and animal matter. Some great options for their diet include:

  • High-quality flakes or pellets
  • Frozen or live brine shrimp
  • Frozen or live bloodworms
  • Frozen or live daphnia
  • Frozen or live krill

It’s important to note that Marble Angelfish are prone to bloat, so avoid overfeeding or feeding them foods that are high in fat.


When it comes to how often to feed your Marble Angelfish, it’s recommended to feed them small amounts 2-3 times a day. This will prevent overfeeding and ensure they are getting the nutrients they need.


Here are some additional tips to keep in mind when it comes to feeding your Marble Angelfish:

  • Remove any uneaten food after 5-10 minutes to prevent it from polluting the water.
  • Consider adding some live plants to their aquarium, as they will nibble on them and help with their digestion.
  • Make sure to provide them with a balanced diet, as a lack of nutrition can lead to health problems.

Overall, feeding your Marble Angelfish a balanced diet is crucial to their health and well-being.

By providing them with a varied diet, feeding them small amounts 2-3 times a day, and keeping these tips in mind, you can ensure they are getting the nutrients they need to thrive.

Personally, I have found that my Marble Angelfish love frozen bloodworms and daphnia.

Whenever I feed them, they get so excited and swim up to the surface to greet me. It’s a small but rewarding moment that reminds me of the joy of being an aquarist.

Common Diseases


I have found that Marble Angelfish are generally hardy and disease-resistant if they are kept in a clean and well-maintained aquarium.

However, there are still some diseases that can affect them. One common disease that I have experienced is Ich, which is caused by a parasite that attaches itself to the fish’s skin and fins.

Another disease that can affect Marble Angelfish is Fin Rot, which is caused by bacteria that infect the fins and can spread to the rest of the body.


If your Marble Angelfish has Ich, you may notice white spots on its body and fins, along with scratching and rubbing against objects in the aquarium.

If it has Fin Rot, you may notice that its fins appear ragged and frayed, and may even start to rot away. Other symptoms of both diseases include lethargy, loss of appetite, and rapid breathing.


If you notice any of these symptoms, it is important to act quickly to treat the disease. For Ich, you can use medication that is specifically designed to kill the parasite.

For Fin Rot, you can use antibiotics to kill the bacteria. It is important to follow the instructions on the medication carefully and to continue treatment until the disease is completely gone.


The best way to prevent diseases in Marble Angelfish is to keep their aquarium clean and well-maintained.

This includes regular water changes, cleaning the filter, and removing any uneaten food or debris from the aquarium.

It is also important to quarantine any new fish before adding them to the aquarium, to prevent the spread of disease to your existing fish.

One personal anecdote I have is when I first started keeping Marble Angelfish, I didn’t realize the importance of keeping their aquarium clean.

I ended up losing a few fish to Fin Rot before I learned my lesson and started keeping their environment clean and well-maintained. Since then, I haven’t had any issues with disease in my Marble Angelfish.

Signs of a Healthy Marble Angelfish

As an aquarium enthusiast, I have come across my fair share of sick and unhealthy fish. It’s important to keep an eye on your marble angelfish to ensure they are healthy and thriving in their environment. Here are some signs to look out for:

  1. Active Behavior: A healthy marble angelfish will be active and swimming around their tank. They should be curious about their surroundings and eager to explore.
  2. Bright Colors: The colors of a healthy marble angelfish should be bright and vibrant. Dull or faded colors could be a sign of stress or illness.
  3. Clear Eyes: The eyes of a healthy fish should be clear and free of any cloudiness or discoloration. Cloudy eyes could be a sign of bacterial infection or poor water quality.
  4. Healthy Fins: The fins of a healthy marble angelfish should be fully extended and free of any tears or damage. Damaged fins could be a sign of aggression from other fish in the tank or poor water conditions.
  5. Good Appetite: A healthy marble angelfish should have a good appetite and be eager to eat. If your fish is not eating, it could be a sign of illness or stress.

Remember, prevention is key when it comes to keeping your fish healthy. Make sure to maintain proper water quality, provide a balanced diet, and keep an eye out for any signs of illness or stress. By doing so, you can ensure that your marble angelfish will live a long and healthy life in your aquarium.

Signs Your Marble Angelfish is Sick

If you’re a new fish owner, it may be hard to tell when your Marble Angelfish is sick. Here are some signs to look out for:

  1. Loss of appetite: If your Marble Angelfish is not interested in eating, it may be a sign of illness.
  2. Erratic swimming: If your Marble Angelfish is swimming erratically or struggling to swim, it could be a sign of a health problem.
  3. Change in color: If your Marble Angelfish’s color changes or becomes dull, it may be a sign of stress or illness.
  4. Visible signs of disease: Look for signs of disease such as white spots, redness, or inflammation on your Marble Angelfish’s body.

If you notice any of these signs, it’s important to take action quickly. A sick fish can quickly deteriorate and even die if not treated promptly.

Personal Anecdote: I once had a Marble Angelfish that stopped eating and became lethargic. I immediately contacted my local fish store and they recommended a medication to treat the illness. After a few days of treatment, my Marble Angelfish was back to its active and healthy self.

Breeding Setup

Before breeding Marble Angelfish, it is important to create the right environment for them. I recommend setting up a separate breeding tank that is at least 20 gallons in size.

The tank should be filled with soft, acidic water and have plenty of hiding places, like plants and rocks. The temperature of the water should be around 80°F.

You will also need to provide a flat surface for the fish to lay their eggs on. I usually use a large leaf or a piece of slate. Make sure the surface is clean and free of any debris before placing it in the tank.

How To Breed

To breed Marble Angelfish, you will need a male and a female. They will usually pair off on their own, but if they don’t, you can try introducing them to each other in the breeding tank.

Once the fish have paired off, they will begin to clean a flat surface in the tank and lay their eggs on it. The eggs will hatch in about 2-3 days, and the fry will become free-swimming after about a week.

It is important to remove the parents from the breeding tank once the eggs have been laid, as they may eat the eggs or fry.


After the fry become free-swimming, you will need to feed them small amounts of food several times a day. I recommend using a high-quality fry food or freshly hatched brine shrimp.

You will also need to keep the water in the breeding tank clean to prevent any infections or diseases from spreading. I suggest doing small water changes every day to keep the water quality high.

Overall, breeding Marble Angelfish can be a rewarding experience for any fish enthusiast. With the right setup and care, you can successfully breed these beautiful fish and watch their fry grow and thrive.

Personally, I have bred Marble Angelfish several times and have found it to be a fascinating process. It is amazing to watch the fish pair off and care for their eggs and fry. If you are considering breeding Marble Angelfish, I highly recommend giving it a try!
